How to Write Topic Sentences | 4 Steps, Examples & Purpose

Published on July 21, 2022 by Shona McCombes . Revised on June 5, 2023.

Every paragraph in your paper needs a topic sentence . The topic sentence expresses what the paragraph is about. It should include two key things:

The topic of the paragraph
The central point of the paragraph.

After the topic sentence, you expand on the point zwith evidence and examples.

To build a well-structured argument, you can also use your topic sentences to transition smoothly between paragraphs and show the connections between your points.

Writing strong topic sentences, topic sentences as transitions between paragraphs, topic sentences that introduce more than one paragraph, where does the topic sentence go, frequently asked questions about topic sentences.

Topic sentences aren’t the first or the last thing you write—you’ll develop them throughout the writing process. To make sure every topic sentence and paragraph serves your argument, follow these steps.

Step 1: Write a thesis statement

The first step to developing your topic sentences is to make sure you have a strong thesis statement . The thesis statement sums up the purpose and argument of the whole paper.

Thesis statement example

Food is an increasingly urgent environmental issue, and to reduce humans’ impact on the planet, it is necessary to change global patterns of food production and consumption.

Step 2: Make an essay outline and draft topic sentences

Next, you should make an outline of your essay’s structure , planning what you want to say in each paragraph and what evidence you’ll use.

At this stage, you can draft a topic sentence that sums up the main point you want to make in each paragraph. The topic sentences should be more specific than the thesis statement, but always clearly related to it.

Topic sentence example

Research has consistently shown that the meat industry has a significant environmental impact .

Step 3: Expand with evidence

The rest of the paragraph should flow logically from the topic sentence, expanding on the point with evidence, examples, or argumentation. This helps keep your paragraphs focused: everything you write should relate to the central idea expressed in the topic sentence.

In our example, you might mention specific research studies and statistics that support your point about the overall impact of the meat industry.

Step 4: Refine your topic sentences

Topic sentences usually start out as simple statements. But it’s important to revise them as you write, making sure they match the content of each paragraph.

A good topic sentence is specific enough to give a clear sense of what to expect from the paragraph, but general enough that it doesn’t give everything away. You can think of it like a signpost: it should tell the reader which direction your argument is going in.

To make your writing stronger and ensure the connections between your paragraphs are clear and logical, you can also use topic sentences to create smooth transitions. To improve sentence flow even more, you can also utilize the paraphrase tool .

As you write each topic sentence, ask yourself: how does this point relate to what you wrote in the preceding paragraph? It’s often helpful to use transition words in your topic sentences to show the connections between your ideas.

Emphasize and expand

If the paragraph goes into more detail or gives another example to make the same point, the topic sentence can use words that imply emphasis or similarity (for example, furthermore , indeed , in fact , also ).

Indeed , cattle farming alone is responsible for a large proportion of greenhouse gas emissions.

Summarize and anticipate

If the paragraph turns to a different aspect of the same subject, the topic sentence can briefly sum up the previous paragraph and anticipate the new information that will appear in this one.

While beef clearly has the most dramatic footprint, other animal products also have serious impacts in terms of emissions, water and land use.

Compare and contrast

If the paragraph makes a comparison or introduces contrasting information, the topic sentence can use words that highlight difference or conflict (for example, in contrast , however , yet , on the other hand ).

However , the environmental costs of dietary choices are not always clear-cut; in some cases, small-scale livestock farming is more sustainable than plant-based food production.

You can also imply contrast or complicate your argument by formulating the topic sentence as a question.

Is veganism the only solution, or are there more sustainable ways of producing meat and dairy?

Sometimes you can use a topic sentence to introduce several paragraphs at once.

All of the examples above address the environmental impact of meat-eating versus veganism. Together, they make up one coherent part of a larger argument, so the first paragraph could use a topic sentence to introduce the whole section.

In countries with high levels of meat consumption, a move towards plant-based diets is the most obvious route to making food more sustainable. Research has consistently shown that the meat industry has significant environmental impacts.

The topic sentence usually goes at the very start of a paragraph, but sometimes it can come later to indicate a change of direction in the paragraph’s argument.

Given this evidence of the meat industry’s impact on the planet, veganism seems like the only environmentally responsible option for consumers. However, the environmental costs of dietary choices are not always clear-cut; in some cases, small-scale livestock farming is more sustainable than plant-based food production.

In this example, the first sentence summarizes the main point that has been made so far. Then the topic sentence indicates that this paragraph will address evidence that complicates or contradicts that point.

In more advanced or creative forms of academic writing , you can play with the placement of topic sentences to build suspense and give your arguments more force. But if in doubt, to keep your research paper clear and focused, the easiest method is to place the topic sentence at the start of the paragraph.

A topic sentence is a sentence that expresses the main point of a paragraph . Everything else in the paragraph should relate to the topic sentence.

Topic sentences help keep your writing focused and guide the reader through your argument.

In an essay or paper , each paragraph should focus on a single idea. By stating the main idea in the topic sentence, you clarify what the paragraph is about for both yourself and your reader.

The topic sentence usually comes at the very start of the paragraph .

However, sometimes you might start with a transition sentence to summarize what was discussed in previous paragraphs, followed by the topic sentence that expresses the focus of the current paragraph.

Let’s say you’re writing a five-paragraph essay about the environmental impacts of dietary choices. Here are three examples of topic sentences you could use for each of the three body paragraphs :

Research has shown that the meat industry has severe environmental impacts.
However, many plant-based foods are also produced in environmentally damaging ways.
It’s important to consider not only what type of diet we eat, but where our food comes from and how it is produced.

Each of these sentences expresses one main idea – by listing them in order, we can see the overall structure of the essay at a glance. Each paragraph will expand on the topic sentence with relevant detail, evidence, and arguments.

Topic sentences and signposts make an essay's claims clear to a reader. Good essays contain both. Topic sentences reveal the main point of a paragraph. They show the relationship of each paragraph to the essay's thesis, telegraph the point of a paragraph, and tell your reader what to expect in the paragraph that follows. Topic sentences also establish their relevance right away, making clear why the points they're making are important to the essay's main ideas. They argue rather than report. Signposts , as their name suggests, prepare the reader for a change in the argument's direction. They show how far the essay's argument has progressed vis-ˆ-vis the claims of the thesis.

Topic sentences and signposts occupy a middle ground in the writing process. They are neither the first thing a writer needs to address (thesis and the broad strokes of an essay's structure are); nor are they the last (that's when you attend to sentence-level editing and polishing). Topic sentences and signposts deliver an essay's structure and meaning to a reader, so they are useful diagnostic tools to the writer—they let you know if your thesis is arguable—and essential guides to the reader

Forms of Topic Sentences

Sometimes topic sentences are actually two or even three sentences long. If the first makes a claim, the second might reflect on that claim, explaining it further. Think of these sentences as asking and answering two critical questions: How does the phenomenon you're discussing operate? Why does it operate as it does?

There's no set formula for writing a topic sentence. Rather, you should work to vary the form your topic sentences take. Repeated too often, any method grows wearisome. Here are a few approaches.

Complex sentences. Topic sentences at the beginning of a paragraph frequently combine with a transition from the previous paragraph. This might be done by writing a sentence that contains both subordinate and independent clauses, as in the example below.

Although Young Woman with a Water Pitcher depicts an unknown, middle-class woman at an ordinary task, the image is more than "realistic"; the painter [Vermeer] has imposed his own order upon it to strengthen it.

This sentence employs a useful principle of transitions: always move from old to new information. The subordinate clause (from "although" to "task") recaps information from previous paragraphs; the independent clauses (starting with "the image" and "the painter") introduce the new information—a claim about how the image works ("more than Ôrealistic'") and why it works as it does (Vermeer "strengthens" the image by "imposing order").

Questions. Questions, sometimes in pairs, also make good topic sentences (and signposts). Consider the following: "Does the promise of stability justify this unchanging hierarchy?" We may fairly assume that the paragraph or section that follows will answer the question. Questions are by definition a form of inquiry, and thus demand an answer. Good essays strive for this forward momentum.

Bridge sentences. Like questions, "bridge sentences" (the term is John Trimble's) make an excellent substitute for more formal topic sentences. Bridge sentences indicate both what came before and what comes next (they "bridge" paragraphs) without the formal trappings of multiple clauses: "But there is a clue to this puzzle."

Pivots. Topic sentences don't always appear at the beginning of a paragraph. When they come in the middle, they indicate that the paragraph will change direction, or "pivot." This strategy is particularly useful for dealing with counter-evidence: a paragraph starts out conceding a point or stating a fact ("Psychologist Sharon Hymer uses the term Ônarcissistic friendship' to describe the early stage of a friendship like the one between Celie and Shug"); after following up on this initial statement with evidence, it then reverses direction and establishes a claim ("Yet ... this narcissistic stage of Celie and Shug's relationship is merely a transitory one. Hymer herself concedes . . . "). The pivot always needs a signal, a word like "but," "yet," or "however," or a longer phrase or sentence that indicates an about-face. It often needs more than one sentence to make its point.

Signposts operate as topic sentences for whole sections in an essay. (In longer essays, sections often contain more than a single paragraph.) They inform a reader that the essay is taking a turn in its argument: delving into a related topic such as a counter-argument, stepping up its claims with a complication, or pausing to give essential historical or scholarly background. Because they reveal the architecture of the essay itself, signposts remind readers of what the essay's stakes are: what it's about, and why it's being written.

Signposting can be accomplished in a sentence or two at the beginning of a paragraph or in whole paragraphs that serve as transitions between one part of the argument and the next. The following example comes from an essay examining how a painting by Monet, The Gare Saint-Lazare: Arrival of a Train, challenges Zola's declarations about Impressionist art. The student writer wonders whether Monet's Impressionism is really as devoted to avoiding "ideas" in favor of direct sense impressions as Zola's claims would seem to suggest. This is the start of the essay's third section:

It is evident in this painting that Monet found his Gare Saint-Lazare motif fascinating at the most fundamental level of the play of light as well as the loftiest level of social relevance. Arrival of a Train explores both extremes of expression. At the fundamental extreme, Monet satisfies the Impressionist objective of capturing the full-spectrum effects of light on a scene.

The writer signposts this section in the first sentence, reminding readers of the stakes of the essay itself with the simultaneous references to sense impression ("play of light") and intellectual content ("social relevance"). The second sentence follows up on this idea, while the third serves as a topic sentence for the paragraph. The paragraph after that starts off with a topic sentence about the "cultural message" of the painting, something that the signposting sentence predicts by not only reminding readers of the essay's stakes but also, and quite clearly, indicating what the section itself will contain.

Types of Topic Sentences

There are several different types of topic sentences that can be used in writing to introduce the reader through a paragraph or essay.

Simple Statement Topic Sentence This is the most common type of topic sentence, which straightforwardly states the main point or idea of the paragraph or essay.

Example: The rise of social media has revolutionized the way people communicate with each other.

Complex Topic Sentence This type of topic sentence is more nuanced and may require some explanation or elaboration to fully understand.

Example: While the rise of social media has had many positive effects on communication, it has also led to concerns about privacy and online harassment.

Pivot Topic Sentence A pivot topic sentence begins by connecting the current paragraph or idea to the previous one, before pivoting to introduce a new point or idea.

Example: Building on the idea of social media's impact on communication, it is important to consider how it has also affected business and marketing strategies.

Question Topic Sentence A question topic sentence poses a question that the rest of the paragraph or essay will answer or explore.

Example: How has social media changed the way businesses interact with customers and advertise their products?

Command Topic Sentence This type of topic sentence gives a directive or instruction, often used in persuasive or argumentative essays.

Example: Support local businesses by shopping at independently owned stores instead of large chains.

How to Write a Topic Sentence?

Here are a few instructions to help you write a good topic sentence.

Step#1 Clearly State The Main Idea

A topic sentence is the first paragraph of the paragraph. It must clearly explain the particular subject that would be discussed in the paragraph. This should be stated in very clear language so that the reader can easily understand the idea.

Also, it should include a bit of your personal opinion and also the main idea.

Step#2 Hook Your Reader

Grab your reader's attention with an intriguing topic sentence. It would excite and make the reader curious about the content and convince them to read the particular part.

Look out for some amazing hook examples and see what fits your essay type.

Use a meaningful and relevant question or a fact as a topic sentence of the paragraph. Make sure that you have identified your audience and are developing everything accordingly.

Step#3 Keep It Short and Precise

The paragraph topic sentence must be expressive enough that a reader understands your point of view effortlessly. This is only possible if you keep everything to the point, short, and meaningful.

Choose the words in such a way that they help you express your idea in an ideal way. Avoid using complex sentences and use independent clauses.

A topic sentence acts as a link between a paragraph and the main thesis statement. It should be specific and connected to the overall essay. Keeping it short and precise helps maintain the paragraph's flow and its relevance to the rest of the writing.

Step#4 Give A Reasonable Opinion

The body paragraph explains a topic sentence. This is why it is important that you should write this sentence in such a way that it can be explained in the paragraph. If you are mentioning a fact in the topic statement, make sure that you have authentic evidence to support it.

While the topic sentence is an integral part of the paragraph, it should stand out and possess a distinctiveness that sets it apart from the other sentences. This can be achieved by employing transition words and establishing connections between sentences.

Step#5 Use The Topic Sentence As A Transition

The topic sentences that serve as transition sentences can be considered a guide for the readers. This way, they can help the reader to move through the essay in a flow.

Write this sentence in such a way that it creates a gateway between the previous paragraph and the rest of the essay. Moreover, it will also help keep the essay organized, and the reader understands the point of a paragraph.

Step#6 Look For Some Good Examples

Examples can help you learn a thing in a better way. If you are new to writing topic sentences, it can help to look at some examples. Find some great examples of topic sentences relevant to your essay topic.

Difference Between Topic Sentence and Thesis Sentence

Here's a table outlining the differences between a topic sentence and a thesis statement:

Good Topic Sentence Examples

Here are ten examples of good topic sentences:

"Despite the advancements in technology, traditional forms of communication are still essential in today's society."
"The theme of power is prevalent throughout Shakespeare's play, Macbeth."
"In recent years, there has been a growing concern over the impact of climate change on our planet."
"The legalization of marijuana has been a topic of debate for many years." "Education is the key to success in life."
"The rise of social media has greatly impacted the way we communicate with one another."
"The effects of childhood trauma can have a lasting impact on mental health."
"The concept of justice is explored in depth in Harper Lee's To Kill a Mockingbird."
"Eating a balanced diet is crucial for maintaining good health."
"The Industrial Revolution had a profound effect on the world as we know it today."

The Bottom Line!

An opening sentence is crucial to grab your reader's attention and set the tone for your piece of writing. The topic sentence introduces the controlling idea and acts as an important sentence in the essay outline.

Effective topic sentences are necessary for a well-structured and organized essay. It's an integral part of the writing process that should not be overlooked.

Common pitfalls to avoid.

Crafting the perfect essay takes time and dedication. There are so many elements you have to worry about, such as tone, purpose, and correct spelling and grammar. Writing a strong topic sentences is another critical part in writing a cohesive essay.

Without a strong topic sentence, you risk losing your reader and perhaps part of your grade. If it’s a college admissions essay, then you need it to be as strong as possible to back up your application. Learn about what steps you should take to write a strong topic sentence.

What Is a Topic Sentence?

People often confuse a topic sentence with a thesis statement. A thesis statement is typically at the end of your opening paragraph, that dictates the main argument you’ll be making in your essay.

Throughout your essay, you’ll have multiple topic sentences, as each paragraph should start off with one. This beginning sentence is used to direct the topic of the paragraph and outline the flow of the following sentences. It’s used to help guide your reader and to continue to keep them hooked on your overall essay. Without topic sentences, your essay will be unorganized, lack transitions, and sound very choppy. To write a good topic sentence, there are several steps to take.

Writing a Good Topic Sentence: 5 Steps

Step 1: decide what you’re going to write about..

When you see the essay prompt, you’ll have some time to think through what you want to say and why. You have to decide if it’s a persuasive essay, informative, narrative, or descriptive. Determine your purpose for writing the essay after reading through the prompt. Whether it’s an assignment for school or if it’s to get into college, you need to make sure you have that purpose clearly outlined.

Step 2: Create a thesis statement.

One of the first things you need to do is create a thesis statement. This is typically a sentence with three points that you’ll back up throughout your essay.

For example: The Office became a cultural phenomenon because it spurred the careers of many of today’s successful movie stars, it talked about situations that most American workers can relate to, and even 15 years later, offers funny, relevant content that helps to break down prejudices.

You then use that thesis statement to create an essay around the points you want to make.

Step 3: Make your essay outline.

Once you have the points you want to make within your thesis statement hammered out, make an outline for your essay. This is where you’ll start to create your topic sentence for each paragraph. You want to clearly state the main idea of that paragraph in the very first sentence. From there, you back up that main idea with facts and reputable sources. Make sure your topic sentence is clear, but does not just announce your topic.

For example, do not write something like: “In this paragraph, I will discuss why it’s bad that poachers are killing giraffes.”

Instead, write something that clearly states your idea with a reasonable opinion and that gives direction to the paragraph: “Giraffes are a key part of the African ecosystem, so it’s important to enforce regulations against the poachers who are killing them for their body parts.”

You’d then follow that up with reasons why giraffes are a key part of the African ecosystem and how poachers are destroying their population.

Step 4: Begin writing your essay.

Once you have your thesis statement and you’ve created an outline with supporting paragraphs and their topic sentences, you can begin writing your essay. It’s important to make that outline before just jumping in–a disorganized essay can spell disaster for you as you continue to write, and could result in a poor grade. Many times, teachers will even require you to turn in your outline as part of your overall essay grade.

Step 5: Proofread and check your resources.

After you’ve written the essay, go back through it with a fine tooth comb. Read through each topic sentence and the paragraphs that follow to ensure that you’ve written clear, solid topic sentences throughout and that the paragraphs with them make sense. During the proofreading phase, you also need to recheck the sources you’re using. Make sure each source is reputable. In other words, do not use sites like Wikipedia where anyone can go in and edit an article to add misinformation. Use sites that:

Are actual reputable news sources, such as the New York Times , CNN, CBS News
Have domain names that end in .edu or .gov
Come from an encyclopedia, such as Encyclopedia Britannica

Using sites that are not reputable could jeopardize the validity of your argument.

Now that you know the steps to set yourself up for success when writing a topic sentence, there are certain elements that go into a quality first sentence. Always make sure that your topic sentence is the first sentence of a paragraph. You don’t want to make your reader hunt for the point you’re trying to make. Check out some key elements of a good topic sentence:

Make sure your topic sentence isn’t too vague.

You need a topic sentence that has some specifics to it. It also needs to hook in your reader in some way with an opinion. A vague sentence makes it harder to write a paragraph that can clearly backs up your thoughts. For example:

DON’T: “In Pride and Prejudice, Mr. Bingley seems like a nice guy.”

DO: “When Mr. Bingley is first introduced, he comes across as a kind person because he speaks to everyone and doesn’t immediately pass judgment.”

Choose a reasonable opinion.

Your topic sentence should clearly outline whatever point you’re trying to make in the paragraph, but you want to pick a reasonable opinion that you can easily reinforce with facts and statistics. Here’s an example of what you should and should not do:

DON’T: “It’s obvious that Mr. Bingley was a total loser with no backbone.”

DO: “Mr. Bingley could have shown more confidence in his choices and stood up to Mr. Darcy when he found himself in love with Jane Bennet.”

You can then back that up with facts, saying that he was a wealthy Englishman and thus one of the key players in society at the time, which should have given him more confidence. If he’d been more confident, perhaps he would not have left and devastated Jane.

Use your topic sentence as a transition.

Along with telling the reader the point of your next paragraph, your topic sentence should also serve as a transition from the previous paragraph. Without a transition, the essay can feel like it’s choppy and disjointed. For example:

DON’T: “Mr. Bingley is a good man and here’s why.”

DO: “Although Mr. Bingley did break Jane’s heart by leaving, he ended up redeeming himself by returning to Netherfield Hall.”

Keep your topic sentence short.

A long, drawn-out topic sentence can risk losing your reader. Many times, it’s hard to determine the point of a sentence when it goes on for too long. You want a clear, concise sentence that draws in the reader but also leaves some room for you to expand on it in the following paragraph.

DON’T: “Throughout the novel of Pride and Prejudice, Mr. Bingley was often quite different from Mr. Darcy as he would treat all people in a friendly manner, considering them all his friends and acquaintances, even agreeing to throw a ball after Elizabeth’s sisters rudely demanded he do so and was gracious to Mr. and Mrs. Bennet as well despite their manners.”

DO: “Overall, Mr. Bingley served as a foil to Mr. Darcy throughout the story by treating everyone around him equally with dignity and grace.”

Writing an essay can be overwhelming at times, but so long as you avoid some of these common pitfalls, it can be easier to get it done on time.

Don’t wait until the last minute.

If your teacher assigns you an essay or tells you that you have an essay test coming up, don’t wait until the day before to do anything about it. You have to plan or study and you need to give yourself time to do that. If you know it takes you a while to write something, then start planning it as soon as you get the assignment.

Don’t forget to write an outline.

Along with planning, make sure you have that outline written up and planned out well. It will serve as your guideline for writing the essay. Without it, you’ll face the risk of a disorganized essay that does not clearly illustrate your point.

Ask for help if you need it.

This may be the most important pitfall to avoid. If you get in over your head while writing, don’t be afraid to ask for help. Ask a friend to review the essay or ask your teacher for guidance.

Academic Paragraphs: Examples of the MEAL Plan (video transcript)

The best way to understand the role of the topic sentence in paragraph development is to imagine that any given paragraph is a miniature essay that has its own thesis, support, and conclusion. The parts of a paragraph easily correspond to the parts of an essay:

Just as an effective essay starts off with an introduction that presents the paper's thesis statement and indicates the specific claim or argument that the essay will develop, each paragraph should begin with a topic sentence that indicates the focus of that paragraph, alerting the reader to the particular subtopic that the paragraph will provide evidence to support.

A strong topic sentence should be placed at or near the beginning of a paragraph. In addition, this sentence should focus on a specific issue, avoid the use of direct quotations, and leave room for support and analysis within the body of the paragraph. Read on to learn more about creating an effective topic sentence.

The topic sentence does not have to be the first sentence in the paragraph; however, it should come early in the paragraph in order to orient the reader to the paragraph's focus right away. Occasionally a writer may place a transition sentence before the topic sentence, to create continuity between topics.

Topic Sentence to begin paragraph:

In the novel Sula , Morrison uses the physical bonds of female friendship to propel her characters into self-awareness.

Transition Sentence + Topic Sentence to begin paragraph:

However, Morrison does not only use the emotional and spiritual bonds between her female characters to initiate their coming-of-age. In addition, the author uses the physical bonds of female friendship to propel her adolescent protagonists into self-awareness.

Specificity

Your topic sentence should be more narrowly focused than your thesis sentence, and you will want to make sure the claim you are making can be supported, argued, and analyzed within the body of your paragraph.

Example: In the novel Sula , Morrison uses the physical bonds of female friendship to propel her characters into self-awareness.

In this topic sentence, the essayist is arguing that physical bonds of friendship, specifically, make the female characters more self-aware. Because this idea can be refuted or supported by readers (based on how successfully the essayist persuades his or her readers with examples and analysis from the novel), and because the claim is narrow enough to address within a single paragraph, the above sentence is a successful topic sentence.

Direct Quotations (Are Best Avoided)

Although it might be tempting to begin a paragraph with a compelling quotation, as a general rule, topic sentences should state the main idea of the paragraph in your own words. Direct quotations have a place later in the paragraph, where they may be incorporated to support the topic sentence.

Needs Improvement: As Morrison (1982) conveyed, the girls' "friendship let them use each other to grow on…they found in each other's eyes the intimacy they were looking for" (p. 52).

Better: In the novel Sula , Morrison uses the physical bonds of female friendship to propel her characters into self-awareness. Pointing to the connection of eyes meeting and bodies growing together, Morrison makes coming-of-age an interactive physical process between the adolescent protagonists. Specifically, Morrison describes how Sula and Nel have used "each other to grow on…they found in each other's eyes the intimacy they were looking for" (p. 52).

In this second paragraph, the topic sentence appears first, immediately orienting readers to the main focus (or topic) of the paragraph. The quotation is used later in the paragraph as a form of evidence or support for the topic sentence.

If you are finding it challenging to create effective topic sentences, you might consider outlining before beginning to write a paper. The points and subpoints of an outline can then become the topic sentences for the paper's paragraphs.

Additionally, because the topic sentence functions similarly at the paragraph level to the thesis at the essay level, you may also find it helpful to check out our thesis statement construction information. Our resource on paragraphs has helpful information about the scope of a paragraph, as well.

Using Topic Sentences

What is a topic sentence?

A topic sentence states the main point of a paragraph: it serves as a mini-thesis for the paragraph. You might think of it as a signpost for your readers—or a headline—something that alerts them to the most important, interpretive points in your essay. When read in sequence, your essay’s topic sentences will provide a sketch of the essay’s argument. Thus topics sentences help protect your readers from confusion by guiding them through the argument. But topic sentences can also help you to improve your essay by making it easier for you to recognize gaps or weaknesses in your argument.

Where do topic sentences go?

Topic sentences usually appear at the very beginning of paragraphs. In the following example from Anatomy of Criticism , Northrop Frye establishes the figure of the tragic hero as someone more than human, but less than divine. He backs up his claim with examples of characters from literature, religion and mythology whose tragic stature is a function of their ability to mediate between their fellow human beings and a power that transcends the merely human:

The tragic hero is typically on top of the wheel of fortune, half-way between human society on the ground and the something greater in the sky. Prometheus, Adam, and Christ hang between heaven and earth, between a world of paradisal freedom and a world of bondage. Tragic heroes are so much the highest points in their human landscape that they seem the inevitable conductors of the power about them, great trees more likely to be struck by lightning than a clump of grass. Conductors may of course be instruments as well as victims of the divine lightning: Milton’s Samson destroys the Philistine temple with himself, and Hamlet nearly exterminates the Danish court in his own fall.

The structure of Frye’s paragraph is simple yet powerful: the topic sentence makes an abstract point, and the rest of the paragraph elaborates on that point using concrete examples as evidence.

Does a topic sentence have to be at the beginning of a paragraph?

No, though this is usually the most logical place for it. Sometimes a transitional sentence or two will come before a topic sentence:

We found in comedy that the term bomolochos or buffoon need not be restricted to farce, but could be extended to cover comic characters who are primarily entertainers, with the function of increasing or focusing the comic mood. The corresponding contrasting type is the suppliant, the character, often female, who presents a picture of unmitigated helplessness and destitution. Such a figure is pathetic, and pathos, though it seems a gentler and more relaxed mood than tragedy, is even more terrifying. Its basis is the exclusion of an individual from the group; hence it attacks the deepest fear in ourselves that we possess—a fear much deeper than the relatively cosy and sociable bogey of hell. In the suppliant pity and terror are brought to the highest possible pitch of intensity, and the awful consequences of rejecting the suppliant for all concerned is a central theme of Greek tragedy.

The context for this passage is an extended discussion of the characteristics of tragedy. In this paragraph, Frye begins by drawing a parallel between the figure of the buffoon in comedy and that of the suppliant in tragedy. His discussion of the buffoon occurred in a earlier section of the chapter, a section devoted to comedy. The first sentence of the current paragraph is transitional: it prepares the way for the topic sentence. The delayed topic sentence contributes to the coherence of Frye’s discussion by drawing an explicit connection between key ideas in the book. In essays, the connection is usually between the last paragraph and the current one.

Sometimes writers save a topic sentence for the end of a paragraph. You may, for example, occasionally find that giving away your point at the beginning of a paragraph does not allow you to build your argument toward an effective climax.

How do I come up with a topic sentence? And what makes a good one?

Ask yourself what’s going on in your paragraph. Why have you chosen to include the information you have? Why is the paragraph important in the context of your argument? What point are you trying to make?

Relating your topic sentences to your thesis can help strengthen the coherence of your essay. If you include a thesis statement in your introduction, then think of incorporating a keyword from that statement into the topic sentence. But you need not be overly explicit when you echo the thesis statement. Better to be subtle rather than heavy-handed. Do not forget that your topic sentence should do more than just establish a connection between your paragraph and your thesis. Use a topic sentence to show how your paragraph contributes to the development of your argument by moving it that one extra step forward. If your topic sentence merely restates your thesis, then either your paragraph is redundant or your topic sentence needs to be reformulated. If several of your topic sentences restate your thesis, even if they do so in different words, then your essay is probably repetitive.

Does every paragraph need one?

No, but most do. Sometimes a paragraph helps to develop the same point as in the previous paragraph, and so a new topic sentence would be redundant. And sometimes the evidence in your paragraph makes your point so effectively that your topic sentence can remain implicit. But if you are in doubt, it’s best to use one.

Writing Topic Sentences — Purpose, Structure, and Examples

What is a topic sentence?

A topic sentence in academic writing identifies how a body paragraph relates to the overall purpose of an essay stated in the thesis statement . Topic sentences are usually at the beginning of a paragraph and identify the paragraph’s controlling idea.

While an essay’s thesis statement identifies the point of the essay in its entirety, the topic sentence has a much narrower focus, as it relates only to the paragraph in which it is located.

What is the purpose of a topic sentence?

The purpose of a topic sentence is to inform the reader of the main idea of the paragraph and how it connects to the overall objective of the essay. An effective topic sentence accomplishes one or more of the following:

Makes a claim

Supports other claims made in the paper

Identifies the purpose of the rest of the paragraph

Relates the paragraph to the purpose of the paper

Precedes information that defends a claim

How to write a topic sentence

To write a topic sentence, incorporate the following guidelines:

Determine the thesis of the essay.

Identify the main supports that help prove the thesis.

Use each main support to structure a topic sentence for each paragraph.

Compose a sentence that answers the following questions:

What will the paragraph prove?

How does the paragraph connect to the thesis?

Where is the topic sentence in a paragraph?

Topic sentences can be placed at the beginning or end of a paragraph.

Although it does not need to be the first sentence, the topic sentence should be placed at the beginning of the paragraph so the reader can quickly identify the purpose of the paragraph.

While not a common placement for a topic sentence, some writers use topic sentences at the end of a paragraph. Writers who choose this method want the reader to deduce the main point of the paragraph by presenting the evidence first.

Topic sentence examples

The following list identifies topic sentences based on the provided thesis statements for five-paragraph essays:

Thesis Statement: Capital punishment should be banned because it is inhumane, unconstitutional, and ineffective at deterring crime.

Support Paragraph 1 Topic Sentence: The inhumane nature of the death penalty proves it should be abolished.

Support Paragraph 2 Topic Sentence: Capital punishment should be outlawed because it violates the Constitution.

Support Paragraph 3 Topic Sentence: Because the death penalty does not effectively deter criminal behavior, states should not continue to use it.

Thesis Statement: College athletes should be financially compensated because they sacrifice their minds and bodies, cannot hold an outside job, and increase the school’s revenue.

Support Paragraph 1 Topic Sentence: Student athletes should be paid for their performance because of sports’ impact on their minds and bodies.

Support Paragraph 2 Topic Sentence: Because most college athletes cannot play their sport and hold a job, colleges should give them a living wage.

Support Paragraph 3 Topic Sentence: Student-athletes’ ability to increase their college’s revenue proves they should be awarded financial compensation.

Thesis Statement: Using alternative energy sources can help lessen the impact of global climate change.

Support Paragraph 1 Topic Sentence: Through the widespread use of solar power, countries can limit the environmental impact of other energy sources.

Support Paragraph 2 Topic Sentence: Utilizing more wind turbines as a power source can help mitigate the effects of climate change.

Support Paragraph 3 Topic Sentence: Using geothermal power will effectively decrease the world's reliance on fossil fuels.

What is a Topic Sentence? (Definition, Examples, How to Use)

What is a topic sentence ? A topic sentence , the first sentence of a paragraph, presents the main concept discussed in the paragraph. It must contain sufficient information to support numerous examples and subtopics without being too broad to obscure the essay’s intended purpose. The remaining sentences in the paragraph will act as supporting statements, providing evidence and examples for the main idea.

Importance of topic sentences

In essays or articles , where subjects can shift from one paragraph to another, a topic phrase is particularly crucial. The topic sentences, superficially, may seem to serve the purpose of only acting like the initial or introductory sentence of a paragraph. But it has numerous other purposes that make it an important part of essays.

Topic sentences link paragraphs together to improve the sentence flow and make reading easier. When topic sentences are not used, switching between paragraphs can feel abrupt and jarring to the reader. Authors can maintain the rhythm of their writing using topic sentences and facilitate smooth transitions.
Topic sentences show the reader a sample of what to expect from the paragraph. The readers can determine from the topic sentence whether the paragraph will comprise a narrative, a list, anecdotal evidence, statistical data, persuasive opinions, or some other form of evidence.
If two conflicting viewpoints are presented in a single paragraph, authors can use more than one topic sentence to inform the readers about the changes in the main concept. For example, paragraphs that “compare and contrast” require more than one topic sentence. In these kinds of paragraphs, authors can start with a topic sentence introducing the first idea and follow it up with proof or evidence supporting the idea. Then they can introduce the second topic sentence conveying the opposing viewpoint, followed by proof or evidence supporting it.

Different types of topic sentences

The different types of topic sentences include:

Simple statement

This topic sentence is used by authors to make a general observation or statement and then elaborate on it in the body of the paragraph.

New studies are emerging indicating the link between climate change and the emergence of numerous new virus strains.

Interrogative or question

This is used by writers in less formal settings. Authors can start a paragraph using implicit or explicit questions related to the topic of discussion to engage the readers.

How many nations are ready to adapt to rising sea levels?

Complex topic sentences are used when the author is discussing a complicated concept that encompasses multiple ideas. Such topic sentences cover more than a single core idea.

Although many people believe that a mother bird will reject its chick if it is touched by humans, the truth is that birds do not abandon their babies after humans touch them.

Authors can use their topic sentences to make explicit demands or pleas to their readers. This will be helpful in breaking the monotony of the essay.

Let’s look at the data from the latest research.

Purely transitional

Though topic sentences are generally responsible for facilitating a smooth transition between paragraphs, occasionally they are purely transitional. These function best when the main topic shifts abruptly by highlighting the switch.

But not everybody agrees.

Pivot sentences are not found at the beginning of a paragraph but rather in the middle, indicating a change in the topic. Conjunctive adverbs like however, furthermore, and meanwhile are frequently used with them.

However, the undisputed king of tennis, Roger Federer, was dethroned in 2008 at Wimbledon.

How to create good topic sentences

A good topic sentence can be created using some simple steps:

1. Determine the key point of your essay

Writers should first form an understanding of the topic of the essay and then create topic sentences to attract the attention of readers. Constructing a good thesis statement can assist the writer in forming better topic sentences.

2. Have an outline for the essay

The author should form a plan or roadmap beforehand on the topics they want to discuss in a paragraph and the evidence they want to use as supporting statements.

3. Be coherent and clear

Writers should make their topic sentences clear and comprehensible so that the reader can form a clear understanding of what to expect in the paragraph.

4. Share opinions

It is advisable to share the opinion or viewpoint of the author in the topic sentence to attract the attention of the reader. Authors should also refrain from writing obvious facts in the topic sentences.

5. Use specific wordings

The topic sentences ought to be precise enough so that the authors can use a few sentences in the paragraph to support them.

6. Transitions should be added between paragraphs

To give the essay or paper a throughline, authors can create topic sentences that refer to the prior paragraph. A topic sentence can make a reference to the preceding paragraph while introducing the next part by using transitional words.

7. Use new, relevant information

Instead of using an obvious fact that everybody knows as the topic sentence, authors can give new information. It is also important to present them in an interesting way.

8. Create a compound or complex topic statement

Compound or complex topic statements feel advanced and stronger. Authors can create such topic statements to add a high level of sophistication to their text.

Many beginner writers and students confuse thesis statements with topic sentences. In essence, thesis statements establish the major idea discussed in the entire essay or paper, as opposed to topic sentences, which introduce the central concept of a paragraph.

Both of these sentences are responsible for giving the readers a sample of what to expect, but in entirely different capacities. Suppose a person is writing a thesis about the different compounds present in coffee and the health benefits it offers.

The thesis statement will be a generalized statement indicating that there are numerous compounds in coffee that benefit the health of humans. But the topic sentence of each paragraph will introduce any single health benefit or compound present in the coffee.

Topic sentences are typically found at the beginning of a paragraph. But this does not mean that they cannot be placed elsewhere in the paragraph. In some cases, when the details discussed can be summarized into a general statement, topic sentences can be included at the end.

Similarly, in some paragraphs where multiple concepts are discussed, topic sentences may be used in the middle of the paragraph. The placement depends on the number of topics being discussed and the way they are discussed.

Paragraphs & topic sentences.

A paragraph is a series of sentences that are organized and coherent, and are all related to a single topic. Almost every piece of writing you do that is longer than a few sentences should be organized into paragraphs. This is because paragraphs show a reader where the subdivisions of an essay begin and end, and thus help the reader see the organization of the essay and grasp its main points.

Paragraphs can contain many different kinds of information. A paragraph could contain a series of brief examples or a single long illustration of a general point. It might describe a place, character, or process; narrate a series of events; compare or contrast two or more things; classify items into categories; or describe causes and effects. Regardless of the kind of information they contain, all paragraphs share certain characteristics. One of the most important of these is a topic sentence.

TOPIC SENTENCES

A well-organized paragraph supports or develops a single controlling idea, which is expressed in a sentence called the topic sentence. A topic sentence has several important functions: it substantiates or supports an essay’s thesis statement; it unifies the content of a paragraph and directs the order of the sentences; and it advises the reader of the subject to be discussed and how the paragraph will discuss it. Readers generally look to the first few sentences in a paragraph to determine the subject and perspective of the paragraph. That’s why it’s often best to put the topic sentence at the very beginning of the paragraph. In some cases, however, it’s more effective to place another sentence before the topic sentence—for example, a sentence linking the current paragraph to the previous one, or one providing background information.

Although most paragraphs should have a topic sentence, there are a few situations when a paragraph might not need a topic sentence. For example, you might be able to omit a topic sentence in a paragraph that narrates a series of events, if a paragraph continues developing an idea that you introduced (with a topic sentence) in the previous paragraph, or if all the sentences and details in a paragraph clearly refer—perhaps indirectly—to a main point. The vast majority of your paragraphs, however, should have a topic sentence.

PARAGRAPH STRUCTURE

Most paragraphs in an essay have a three-part structure—introduction, body, and conclusion. You can see this structure in paragraphs whether they are narrating, describing, comparing, contrasting, or analyzing information. Each part of the paragraph plays an important role in communicating your meaning to your reader.

Introduction : the first section of a paragraph; should include the topic sentence and any other sentences at the beginning of the paragraph that give background information or provide a transition.

Body : follows the introduction; discusses the controlling idea, using facts, arguments, analysis, examples, and other information.

Conclusion : the final section; summarizes the connections between the information discussed in the body of the paragraph and the paragraph’s controlling idea.

The following paragraph illustrates this pattern of organization. In this paragraph the topic sentence and concluding sentence (CAPITALIZED) both help the reader keep the paragraph’s main point in mind.

SCIENTISTS HAVE LEARNED TO SUPPLEMENT THE SENSE OF SIGHT IN NUMEROUS WAYS. In front of the tiny pupil of the eye they put , on Mount Palomar, a great monocle 200 inches in diameter, and with it see 2000 times farther into the depths of space. Or they look through a small pair of lenses arranged as a microscope into a drop of water or blood, and magnify by as much as 2000 diameters the living creatures there, many of which are among man’s most dangerous enemies. Or , if we want to see distant happenings on earth, they use some of the previously wasted electromagnetic waves to carry television images which they re-create as light by whipping tiny crystals on a screen with electrons in a vacuum. Or they can bring happenings of long ago and far away as colored motion pictures, by arranging silver atoms and color-absorbing molecules to force light waves into the patterns of original reality. Or if we want to see into the center of a steel casting or the chest of an injured child, they send the information on a beam of penetrating short-wave X rays, and then convert it back into images we can see on a screen or photograph. THUS ALMOST EVERY TYPE OF ELECTROMAGNETIC RADIATION YET DISCOVERED HAS BEEN USED TO EXTEND OUR SENSE OF SIGHT IN SOME WAY. George Harrison, “Faith and the Scientist”

In a coherent paragraph, each sentence relates clearly to the topic sentence or controlling idea, but there is more to coherence than this. If a paragraph is coherent, each sentence flows smoothly into the next without obvious shifts or jumps. A coherent paragraph also highlights the ties between old information and new information to make the structure of ideas or arguments clear to the reader.

Along with the smooth flow of sentences, a paragraph’s coherence may also be related to its length. If you have written a very long paragraph, one that fills a double-spaced typed page, for example, you should check it carefully to see if it should start a new paragraph where the original paragraph wanders from its controlling idea. On the other hand, if a paragraph is very short (only one or two sentences, perhaps), you may need to develop its controlling idea more thoroughly, or combine it with another paragraph.

A number of other techniques that you can use to establish coherence in paragraphs are described below.

Repeat key words or phrases. Particularly in paragraphs in which you define or identify an important idea or theory, be consistent in how you refer to it. This consistency and repetition will bind the paragraph together and help your reader understand your definition or description.

Create parallel structures. Parallel structures are created by constructing two or more phrases or sentences that have the same grammatical structure and use the same parts of speech. By creating parallel structures you make your sentences clearer and easier to read. In addition, repeating a pattern in a series of consecutive sentences helps your reader see the connections between ideas. In the paragraph above about scientists and the sense of sight, several sentences in the body of the paragraph have been constructed in a parallel way. The parallel structures (which have been emphasized ) help the reader see that the paragraph is organized as a set of examples of a general statement.

Be consistent in point of view, verb tense, and number. Consistency in point of view, verb tense, and number is a subtle but important aspect of coherence. If you shift from the more personal "you" to the impersonal “one,” from past to present tense, or from “a man” to “they,” for example, you make your paragraph less coherent. Such inconsistencies can also confuse your reader and make your argument more difficult to follow.

Use transition words or phrases between sentences and between paragraphs. Transitional expressions emphasize the relationships between ideas, so they help readers follow your train of thought or see connections that they might otherwise miss or misunderstand. The following paragraph shows how carefully chosen transitions (CAPITALIZED) lead the reader smoothly from the introduction to the conclusion of the paragraph.

I don’t wish to deny that the flattened, minuscule head of the large-bodied "stegosaurus" houses little brain from our subjective, top-heavy perspective, BUT I do wish to assert that we should not expect more of the beast. FIRST OF ALL, large animals have relatively smaller brains than related, small animals. The correlation of brain size with body size among kindred animals (all reptiles, all mammals, FOR EXAMPLE) is remarkably regular. AS we move from small to large animals, from mice to elephants or small lizards to Komodo dragons, brain size increases, BUT not so fast as body size. IN OTHER WORDS, bodies grow faster than brains, AND large animals have low ratios of brain weight to body weight. IN FACT, brains grow only about two-thirds as fast as bodies. SINCE we have no reason to believe that large animals are consistently stupider than their smaller relatives, we must conclude that large animals require relatively less brain to do as well as smaller animals. IF we do not recognize this relationship, we are likely to underestimate the mental power of very large animals, dinosaurs in particular. Stephen Jay Gould, “Were Dinosaurs Dumb?”

What Is A Topic Sentence

How to Write a Topic Sentence: Purpose, Tips & Examples

What is a Topic Sentence In An Essay?

In an essay, a topic sentence is the first sentence in a paragraph, and it gives us a sneak peek into what the paragraph will talk about.

It's like a signpost that helps the reader know what's coming up next.

Each topic sentence in a paragraph must have a topic and a controlling idea to show where the information is heading.

What is the Purpose of a Topic Sentence?

The purpose of a topic sentence is to make your writing clear and organized. Think of it like this: if you're telling a story, you wouldn't jump from one topic to another without letting your friends know, right? That would be confusing!

Similarly, in writing, a topic sentence helps your reader know what to expect in each paragraph. It's like a mini-map for your essay.

When you read the topic sentence, you instantly get a sense of what the paragraph will discuss.

Here's why topic sentences are important:

Guides the Reader : It helps the reader understand what each paragraph is about. It's like a helpful signpost along the reading journey.
Keep Your Writing Organized: Just like you wouldn't mix up ingredients when cooking, a topic sentence keeps your ideas in order. It makes sure each paragraph has a clear focus.
Connects Your Ideas : Topic sentences connect one paragraph to the next. They create a smooth flow in your essay, like linking train cars together.
Helps You Stay on Track : As a writer, a topic sentence helps you stay on topic. It reminds you of what you wanted to say in that paragraph.

Paper Due? Why Suffer? That's our Job!

Where Is The Topic Sentence Placed?

The placement of a topic sentence in a paragraph is crucial for conveying the main idea and guiding the reader's understanding.

Typically, the topic sentence is positioned at the beginning of a paragraph. This serves as a clear and concise statement that introduces the central theme or point that the rest of the paragraph will discuss and support.

Elements of a Good Topic Sentence

A good topic sentence possesses several key elements that distinguish it as an effective component of your writing:

Clarity : It should be clear and straightforward, leaving no room for ambiguity or confusion about the paragraph's main point.
Specificity : A strong topic sentence is precise and specific, focusing on a single aspect of the broader topic to maintain a clear direction.
Relevance : It must be directly related to the thesis statement or overall purpose of your writing, ensuring that it contributes to the central argument.
Conciseness : It should be concise and to the point, avoiding unnecessary wordiness and getting straight to the heart of the matter.
Connection : A good topic sentence should establish a clear link to the previous paragraph or the essay's overarching theme, creating a seamless flow of ideas.

Although most of the essay paragraphs must have a topic sentence. But there are some cases when there is no need to add it at all. For example, you can omit if the paragraph continues to develop a story or idea that you introduced in the previous paragraph.

How to Write a Topic Sentence - 5 Simple Steps

Writing an effective topic sentence is a skill that can significantly improve your writing. Follow these five precise steps to craft a compelling topic sentence:

Identify the Main Idea

Be specific and concise, connect to the thesis, check for unity, engage the reader.

Let's break down each of the five steps for writing a topic sentence in more detail:

Before writing your topic sentence, take a moment to identify the main idea of the paragraph. What specific point of view or information in the paragraph do you want to convey?

This is the crux of your paragraph and should be crystal clear in your mind before you start writing.

Once you've identified the main idea, express it in a specific and concise manner. Avoid general statements that lack depth or detail.

Specificity adds clarity to your writing and helps readers understand precisely what you're discussing.

Your topic sentence should align with the thesis statement of your essay or the overall purpose of your document.

This connection ensures that every paragraph contributes directly to your central argument or message. It also keeps your writing coherent and focused.

Ensure that your topic sentence serves as the glue that holds the paragraph together. All the supporting sentences in the paragraph should relate to and reinforce the main idea presented in the topic sentence.

This unity creates a logical and cohesive flow within your writing.

Consider your topic sentence as the hook that captures the reader's attention. Craft it in a way that intrigues the reader and entices them to continue reading.

This engagement is crucial, as it sets the tone for the entire paragraph and encourages readers to invest their time in your content.

Topic Sentences Examples

Here are five examples of topic sentences, along with their respective topics and controlling ideas:

Topic: Climate change
Controlling Idea: Growing threat to global ecosystems
Topic: Time management skills
Controlling Idea: academic success
Topic: Benefits of regular exercise
Controlling Idea: Extend beyond physical health
Topic: Artificial intelligence
Controlling Idea: reshaping the job market
Topic: Digital marketing strategies
Controlling Idea: Transforming business audience reach

Common Pitfalls in Crafting Topic Sentences

When writing a topic sentence, it's important to be aware of common pitfalls and things to avoid to ensure its effectiveness in your writing.

Here are key things to steer clear of:

Vagueness and Ambiguity

Avoid using vague or ambiguous language in your topic sentence. A topic sentence should clearly convey the main idea of the paragraph without leaving readers guessing.

Overly Broad Statements

Steer clear of making sweeping, overly broad statements in your topic sentence. Keep it focused on a specific aspect of the topic to maintain clarity.

Lack of Connection

Ensure your topic sentence connects logically to the previous paragraph or the overall theme of your essay. Avoid abrupt transitions that disrupt the flow of your writing.

Avoid restating the thesis or repeating information from the essay introduction in your topic sentence. Instead, use it to introduce new ideas or aspects of your argument.

Topic sentences introducing complex sentences or information that may confuse readers. Keep it concise and straightforward.

In conclusion, writing effective topic sentences is a skill that can significantly elevate your writing.

By following the steps outlined in this guide, you can ensure that your topic sentences are clear, concise, and engaging.

Remember to identify the main idea, connect to your central argument, engage your readers from the very beginning. Avoid common pitfalls like vagueness, repetition, and lack of relevance, as discussed earlier.

Frequently Asked Questions (FAQs)

What is the difference between a topic sentence and a thesis statement.

A topic sentence is a sentence found at the beginning of a paragraph and introduces the main point of that specific paragraph.

Topic Sentences

Pick up any newspaper or magazine and read the first sentence of an article. Are you fairly confident that you know what the rest of the article is about? If so, you have likely read the topic sentence. An effective topic sentence combines a subject with the writer’s position on that subject or claim about it. It serves to orient the reader and provides an indication of what will follow in the rest of the paragraph. Example:

This topic sentence declares a position in favor of standardizing math and English education. After reading this sentence, a reader might reasonably expect the writer to provide supporting details and facts as to why standardizing math and English education might improve student learning in many states. If the purpose of the essay is actually to evaluate education in only one particular state, or to discuss math or English education specifically, then the topic sentence is misleading and should be revised to say so.

Subject Versus Claim

Good topic sentences contain both a subject (the overall matter, issue, or field of inquiry) and a claim (the writer’s specific point about the subject, or position on it). Different writers may use the same subject but can steer their paragraph in a number of different directions according to their claim, or stance on the subject. Examples:

Marijuana is a destructive influence on teens and causes long-term brain damage.
The anti-nausea properties in marijuana are a lifeline for many cancer patients.
Legalizing marijuana would create a higher demand for Class A and Class B drugs.

Although the subject—marijuana—is the same in all three topic sentences, the claim differs depending on the writer’s viewpoint. For instance, in the first sentence, the claim about marijuana is that it “is a destructive influence on teens and causes long-term brain damage.”

Separately identify the subject and the claim about it in each of the following topic sentences:

1. Exercising three times a week is the only way to maintain good physical health.

2. Sexism and racism are still rampant in today’s workplace.

3. Raising the legal driving age to twenty-one would decrease road traffic accidents.

4. Owning a business is the only way to achieve financial success.

5. Dog owners should be prohibited from taking their pets on public beaches.

Characteristics of a Good Topic Sentence

The following are characteristics good topic sentences:

A good topic sentence provides an accurate indication of what will follow in the rest of the paragraph.

Weak example. People rarely give firefighters the credit they deserve for such a physically and emotionally demanding job. (The paragraph is about a specific incident that involved firefighters; therefore, this topic sentence is too general.)

Stronger example. During the October riots, Unit 3B went beyond the call of duty. (This topic sentence is more specific and indicates that the paragraph will contain information about a particular incident involving Unit 3B.)

A good topic sentence contains both a subject and claim.

Weak example. In this paper, I am going to discuss the rising suicide rate among young professionals. (This topic sentence provides a subject, but it does not present a claim.)

Stronger example. The rising suicide rate among young professionals should become a higher priority among the concerns of human resource departments. (This topic sentence presents the writer’s claim on the subject of rising suicide rates among young professionals.)

A good topic sentence is clear and easy to follow.

Weak example. In general, writing an essay, thesis, or other academic or nonacademic document is considerably easier and of much higher quality if you first construct an outline, of which there are many different types. (This topic sentence includes a subject and claim, but both are buried beneath the confusing sentence structure and unnecessary vocabulary. These obstacles make it difficult for the reader to follow.)

Stronger example. Most forms of writing can be improved by first creating an outline. (This topic sentence cuts out unnecessary words and simplifies the previous statement, making it easier for the reader to follow.)

A good topic sentence does not include supporting details.

Weak example. Salaries should be capped in baseball for many reasons, most importantly so we don’t allow the teams with budgets that exceed their competitors by four or five times to have such an extreme advantage year after year. (This topic sentence includes a supporting detail that should be included later in the paragraph to support the main point.)

Stronger example. Introducing a salary cap would improve the game of baseball for many reasons. (This topic sentence omits the additional supporting detail so that it can be expanded upon later in the paragraph.)

Choose the most effective topic sentence from the following sentence pairs.

1. Which is the more effective topic sentence?

a. This paper will discuss the likelihood of the Democrats winning the next election.

b. To boost their chances of winning the next election, the Democrats need to listen to public opinion.

2. Which is the more effective topic sentence?

a. The unrealistic demands of union workers are crippling the economy for the following three reasons.

b. Union workers are crippling the economy because companies are unable to remain competitive as a result of added financial pressure, which in turn forces companies trying to survive to relocate overseas where non-union wages can be half or in some cases less than half of union wages.

3. Which is the more effective topic sentence?

a. Major companies are stealing back digital content that customers purchased, which is destroying the very concept of ownership.

b. Technology is having drastic effects on how companies deal with digital sales nowadays.

4. Which is the more effective topic sentence?

a. Pop music has lost the genuine heart and superb artistry that it displayed in the past.

b. This essay will consider the quality of pop music.

Using the tips on developing effective topic sentences in this section, create a topic sentence on each of the following subjects. Remember to include the subject as well as the claim.

An endangered species

Students often struggle with writing effective topic sentences. They may find it difficult to come up with ideas or to check if their topic sentences meet the necessary criteria. However, with a few basic tips and some practice, anyone can become a thorough and successful essayist.

In this article, we will provide you with an overview of the dos and don’ts of writing effective topic sentences. We will show you examples of good and bad topic sentences, and provide you with several helpful tips to make the writing process easier. So if you’re ready to learn the nuts and bolts of topic sentences, read on!

Understanding the Importance of Topic Sentences

Topic sentences are a key element in writing, especially when it comes to essays and academic papers. They serve as a guide for the reader, helping them understand the main idea of a paragraph or section. Topic sentences are like the nuts and bolts that hold an essay together, providing structure and coherence to the entire piece.

One of the most important functions of a topic sentence is to introduce the main point or argument of the paragraph. It should be clear and concise, giving the reader a preview of what is to come. A well-written topic sentence sets the tone for the rest of the paragraph and helps the reader stay focused on the main idea.

Another crucial function of topic sentences is to provide specificity and precision. Rather than using vague or general statements, topic sentences should be specific and direct. They should clearly state the main point or argument and avoid excessive fluff or unnecessary words. By being precise, topic sentences make it easier for the reader to understand and follow the writer’s ideas.

Moreover, topic sentences help to organize and structure an essay. They act as a roadmap, guiding the reader through the writer’s thoughts and arguments. By including topic sentences at the beginning of each paragraph, the writer ensures that their ideas are presented in a logical and cohesive way. This not only makes the essay easier to read and understand, but it also helps the writer stay on track and avoid getting off-topic.

Furthermore, topic sentences play a crucial role in supporting the main thesis of an essay. They serve as the foundation for the arguments and evidence that will be presented in the rest of the paragraph. A good topic sentence not only introduces the main point but also provides a preview of the supporting details that will be discussed further. This helps the reader understand the purpose and relevance of the paragraph in relation to the overall thesis.

In addition, topic sentences serve as a checklist for the writer. They help the writer check if their paragraphs meet certain key qualities, such as coherence, relevance, and support. By comparing each topic sentence with the main thesis, the writer can ensure that they are staying on topic and that each paragraph contributes to the overall argument of the essay.

To sum up, topic sentences are essential in guiding the reader through an essay. They introduce the main point, provide specificity, help organize the essay, and support the main thesis. Without topic sentences, an essay can become a road of extra words and ideas, lacking coherence and direction. So, for students and essayists alike, understanding the importance of topic sentences is crucial to writing excellent and effective essays.

The role of topic sentences in effective writing

1. Introduce the main idea: A topic sentence should introduce the main idea of the paragraph or section it belongs to. It sets the stage for what will be discussed and helps the reader understand the purpose of the upcoming text.

2. Be specific: Good topic sentences are precise and focused. They avoid vague or general statements and instead provide a clear direction for the reader to follow. For example, instead of saying “The essay will discuss various reasons for climate change,” a more specific topic sentence could be “Deforestation, industrial emissions, and transportation contribute to climate change.”

3. Make it arg

The Dos of Writing Narrative Topic Sentences

Be specific: A narrative topic sentence should be precise and direct. It should give your readers a clear idea of what is to come and avoid vague language or generalizations. For example, instead of saying “I had a great summer vacation,” you can say “My trip to the Grand Canyon was the highlight of my summer vacation.”
Include a hook: To grab your readers’ attention right from the start, include a hook in your narrative topic sentence. This can be a question, a surprising fact, or a vivid description that entices your readers to continue reading.
Show, don’t tell: Use descriptive language and provide specific examples to engage your readers and make your narrative more engaging. Instead of simply stating what happened, show the action and use sensory details to paint a vivid picture in your readers’ minds.
Follow a logical sequence: Your narrative topic sentence should set the stage for the rest of your narrative. Make sure the points you mention in the topic sentence are presented in a logical and organized manner. This will help your readers follow along easily and understand the flow of your story.
Check grammar and spelling: Before finalizing your topic sentence, double-check for any grammar or spelling mistakes. A well-written topic sentence not only contains the right words but also shows that you have paid attention to grammar and punctuation.

By following these dos when writing your narrative topic sentences, you can ensure that your readers are captivated from the start and eager to read more. Remember to keep them precise, engaging, and well-structured to effectively convey your narrative ideas. With the right topic sentence, your narrative writing is sure to be a success!

Choosing a clear and specific topic for your sentence

Start with a brief overview of your main argument or idea. This will set the tone for the rest of your paragraph and help guide your readers.
Identify the major ideas or points you want to address within the paragraph. You can use bullet points or create an outline to organize your thoughts.
Avoid using quotations or references to other papers or essayists in your topic sentence. Instead, focus on your own ideas and arguments.
Show the importance or relevance of your topic by using real-life examples or concrete evidence. This will give your readers a better understanding of what you are discussing.
Make sure your topic sentence meets the basic grammar rules and sentence structure. Check for proper punctuation, subject-verb agreement, and sentence clarity.

By following these tips, you can ensure that your topic sentence is clear, specific, and effective in introducing your paragraph’s main idea. Remember, the topic sentence is like the rubber hitting the road – it sets the tone and gives your readers an overview of what they can expect within the paragraph. So, rev up your ideas, make them specific, and stop avoiding the extra effort needed to write good topic sentences!

Using active voice to engage the reader

One of the functions of topic sentences is to introduce the main point or argument of a paragraph. When you use active voice in your topic sentence, you make it clear who or what is performing the action, which adds specificity and clarity to your writing. For example, instead of saying “Quotations are useful to support your argument,” you can write “Using quotations supports your argument.” This direct and active sentence makes it clearer who is using the quotations and what purpose they serve.

In addition, using active voice in topic sentences can help you avoid certain grammatical pitfalls. For example, the overuse of passive voice can lead to wordiness, lack of clarity, and a disconnect between the subject and the action. Active voice can help you create more concise and precise topic sentences that clearly and effectively convey your message.

Using active voice can also help you vary the structure of your topic sentences, which adds interest and keeps the reader engaged. Instead of always using the standard subject-verb-object format, you can mix it up by starting with a different part of speech or by adding extra details. For example, instead of saying “Students should stop using vague language in their essays,” you can write “To achieve success as an essayist, students should avoid using vague language in their papers.” This more complex sentence structure adds variety and depth to your writing.

One important point to keep in mind when using active voice in your topic sentences is to ensure that it aligns with the overall purpose of your essay or paper. Active voice works well in certain types of writing, such as argumentative or persuasive essays, where your main goal is to convince the reader of your point of view. However, in other types of writing, such as informative or descriptive essays, passive voice may be more appropriate. It’s crucial to consider the genre and intended audience of your writing to determine the most effective use of active voice.

Crafting concise and focused sentences

So, what’s the best way to craft these sentences and ensure they’re concise and focused? Here are some dos and don’ts to help you:

Use precise and thorough language: Ensure that your topic sentence clearly and accurately expresses the main idea of your paragraph.
Introduce your topic: Start your topic sentence by introducing the topic or the main point you’re going to discuss in the paragraph.
Include specific details or examples: Support your topic sentence by providing specific examples or evidence that further illustrate your main idea.
Show the connection: Clearly show how your topic sentence connects to the overall argument or thesis statement of your essay or paper.
Use parallel structures: Use parallel structures to make your topic sentence more effective and easier to read.

The Don’ts:

Avoid vague or general statements: Make sure your topic sentence is focused and avoids generalizations.
Avoid grammar mistakes: Double-check your topic sentence for grammar errors to ensure clarity and precision.
Avoid excessive quotations: While quotations can be useful, they should be used sparingly and in a way that supports your main argument.
Avoid being too brief or too long: Find a balance between providing enough information and being concise.
Avoid unrelated topics: Stay on topic and avoid introducing unrelated ideas or topics in your topic sentence.

By following these guidelines, you can ensure that your topic sentences are effective in guiding your readers and setting up the main ideas of your paragraphs. Remember, the topic sentence is like the nuts and bolts of your essay or paper, so it’s important to craft them with care.

The Don’ts of Writing Narrative Topic Sentences

Avoid unrelated ideas: Make sure that your topic sentence is closely related to the main argumentative points of your essay. It should be a brief overview of what is to come in the paragraph. Introducing unrelated ideas can confuse the reader and weaken the overall structure of your essay.
Avoid excessive quotations: While incorporating quotations can be helpful, it’s important not to rely too heavily on them. Your topic sentence should be your own words and express your own ideas. Quotations should be used to support and enhance your argument, not to replace your own thoughts.
Avoid grammar and spelling errors: No matter how strong your ideas are, they’re likely to be diminished if they’re accompanied by grammar and spelling mistakes. Take the time to proofread your topic sentences and ensure they’re free of errors. This will help to maintain the credibility of your writing.
Avoid overly general statements: Topic sentences should be specific and to the point. Avoid using general statements that could apply to any topic. Instead, strive for specificity and precision to give your paragraphs a clear and focused direction.

By avoiding these common mistakes, you can write effective topic sentences that serve as a roadmap for your essay. Remember to be specific, avoid unrelated ideas, use your own words, check for grammar and spelling mistakes, and stay away from overly general statements. Following these guidelines will help you create topic sentences that support your argumentative points and lead to the success of your essay.

4.3 Topic Sentences

Amanda Lloyd

Function and Elements of a Topic Sentence

A topic sentence is usually the first sentence of a body paragraph. The purpose of a topic sentence is to identify the topic of your paragraph and indicate the function of that paragraph in some way.

In order to create an effective topic sentence, you should do the following:

Use a transitional device to effortlessly segue from the idea discussed in the previous paragraph.

When choosing a transitional device, you should consider whether your new paragraph will build onto the topic of your previous paragraph, begin to develop a new key idea or sub-claim, or present a counterargument or concession.

See section 4.6 for information regarding when to begin a new paragraph and section 4.7 for help with transitional words and phrases.

Clearly identify the key idea or sub-claim that you intend to expand upon in your new paragraph.

Even if you are building onto the idea of the previous paragraph, you will still need to identify the sub-claim in your topic sentence. When constructing a topic sentence, you may feel as though you are stating the obvious or being repetitive, but your readers will need this information to guide them to a thorough understanding of your ideas.

Make a connection to the claim you make in your thesis statement.

It might help to think of your topic sentence as a mini thesis statement. In your body paragraph, you should be expanding upon the claim you make in your thesis. For this reason, you should link your topic sentence to your thesis statement. Doing so tells your readers, “This is the point I mentioned in my thesis that I now intend to support and either prove or explain further.”

To connect to your thesis, you should consider the function of the body paragraph, which will usually depend upon the type of essay you are writing; for example, your topic sentence should suggest whether your goal is to inform or persuade your readers (your topic sentence should indicate whether or not you have an opinion or perspective on the topic).

Topic Sentences

Writing for yourself vs. writing for others.

Writing for publication can be challenging for a number of reasons. One difficultly you might face when writing for publication can be transitioning from writing for yourself to writing for readers . While it might be a surprise, writing for yourself and writing for others are very different categories. You need to understand the differences between the two before you can write great publishable papers. But to understand the difference between writing for yourself and writing for others, you’ll need to know a little bit about the stages of high-level writing process.

Writing as Discovery

Writing is NOT a linear process; it is a recursive process that requires you to double back to actually discover what you think about a topic. Again this might be quite a surprise. A common metaphor that less inexperienced writers use to think about writing is that writing is merely recording the ideas in your head. This is not true. Beginning graduate-level writers often incorrectly imagine that there is a platonic idea of a paper floating in their heads, and that writing is merely the act of transferring this platonic idea to the page. Again, this is not accurate.

Composition research tells us that as we write, we actually discover what we think. By putting our ideas on paper and reflecting on them, we are able to determine whether we actually hold one stance or another. Responding to counterarguments, contemplating the implications of our findings, and amassing evidence for our claims are activities that can best be reflected on through writing. For example, sometimes making the case of a counterargument that goes against your own claim will convince you and cause you to change your own position, just as the evidence you actually find may lead you to modify your conclusion. Thus, experienced writers know that each draft brings them closer to discovering what they really understand about a topic—something they couldn’t have known before starting.

Uncovering your stance on a topic can be a frustrating and humbling process, but it also allows us as writers to discover larger conclusions and ideas that we couldn’t have realized without the aid of writing. In a sense it allows us to become more expansive versions of ourselves.

Writing to Communicate an Argument

Now that we know that writing actually enables us to figure out our thoughts, we can start to think about how to best approach communicating those thoughts to others. Whereas early drafts of an essay are written in a way that helps the author understand what he/she/they think about the topic, later drafts need to be written in a way that helps readers understand and follow each step of a carefully constructed argument. Put differently, while the early drafts are exploratory in nature, later stages of revision have to consider the information a reader needs to have at hand in order to understand how you achieved your important insights.

One of the key ways to transform an early exploratory draft into a draft tailored to the needs of your readers is by working on your topic sentences. A good topic sentence begins a paragraph in a way that clearly indicates the main analytical purpose of the paragraph.

To understand their importance of a strong topic sentence, we’ll need to think about the purpose of a genre of academic writing like the journal article. At the graduate level, most journal articles are going to be fundamentally argumentative: they are designed to pose a question that has vexed scholars and remained unsolved. Scholars then conduct research that reveals a possible answer to the question. Your manuscripts will inherently argue for the hypothesis that you test through your research.

Once you understand the inherently argumentative nature of manuscripts, you will see that in order to persuade someone of the soundness of your argument, they must know what the argument is .

The function of your topic sentences is to make clear to readers, at the outset, what purpose or idea guides a given paragraph. It is only when readers understand what the paragraph is trying to argue that they are put in a position to judge for themselves whether or not the evidence and/or logical reasoning in that paragraph is convincing to them.

A clear topic sentences will make it easy for your readers to follow the train of thinking that led you to your good idea and, ultimately, to be persuaded by it.

Example of Topic Sentences Working Well

Take a look at the following paragraph:

In the early 1940s, the house band at Minton’s Playhouse played tunes at breakneck speeds to weed out unprepared musicians. The band frequently reharmonized jazz standards, by replacing the original chords with similar chords that shared notes. Often the band would change the key after every chorus and even increase the tempo after each key change. All but the most skilled musicians who sat in with the house band would be left behind by the radical deviations from standard jazz tempo, harmonies, and keys. The result of the house band’s unique style was that the musicians who played at Minton’s developed a new musical vocabulary for jazz: one that moved away from danceability to showcase the speed, rhythmic complexity, harmonic inventiveness, and soloing ability of the performers. The new style was called bebop.

While the individual sentences are intelligible, as readers, we can’t determine why the author is giving us all this information about jazz musicians in the 1940s. It’s only at the end of the paragraph that we start to see that the changes the author describes resulted in the birth of a new musical style.

Now with a topic sentence, we’ll see that the same paragraph starts to snap into place more easily:

The birth of bebop is another example of competitions between musicians leading to the birth of new musical style. In the early 1940s, the house band at Minton’s Playhouse played tunes at breakneck speeds to weed out unprepared musicians. The band frequently reharmonized jazz standards, by replacing the original chords with similar chords that shared notes. Often the band would change the key after every chorus and even increase the tempo after each key change. All but the most skilled musicians who sat in with the house band would be left behind by the radical deviations from standard jazz tempo, harmonies, and keys. The result of the house band’s unique style was that the musicians who played at Minton’s developed a new musical vocabulary for jazz: one that moved away from danceability to showcase the speed, rhythmic complexity, harmonic inventiveness, and soloing ability of the performers. The new style was called bebop.

We can now clearly see what the author wants us to understand about the topic. Now we can make sense of why the author gives us the facts about the musicians: to show how a new style grew into being.

The Four Major Types of Topic Sentences

While the examples might make it look easy to write excellent topic sentences, it can be tricky. Sometimes it can be very hard to consider the one clear idea that each paragraph has. However, there are some guideposts you can follow. GC Writing Center Director Dave Hershinow groups topic sentences into four major categories:

Topic sentences that provide evidence to back up your central claim
Topic sentences that respond to potential counterarguments
Topic sentences that acknowledge complications or limitations in your central claim
Topic sentences that point out further implications of your research

If we look again at the sample paragraph above, you’ll see that it is an instance of the first category. More specifically, it is a topic sentence that lets readers know that the paragraph is going to offer a second example in support of a claim (“The birth of bebop is another example of…”). This paragraph would only make sense when preceded by a paragraph or two that had been dealing with a first, presumably more primary example in support of the same claim. This kind of topic sentence helps readers understand the specific analytical purpose of each paragraph right at the outset, thereby putting readers in the best possible position to follow your analysis with intellectual rigor.

You can use the idea of these four major categories to help you as you write topic sentences. If you realize that you’re trying to accomplish one of these four major goals, it can help you narrow down the idea you’re trying to express and thus make it easier to write a great topic sentence. For example, if you understand that you’re trying to respond to a counterargument, it will be much easier to frame the topic sentence to show clearly what potential counterargument you are rejecting.

Of course, topic sentence writing is still hard! So is revising a draft to suit the needs of your readers. To get all the help you can with these important steps, visit your friends at The Writing Center to get free, one-on-one help with your writing.

How AI can help proofread and edit your essays

Don’t let little mistakes hold you back from getting a better grade. Learn how you can use AI to help you proofread and edit your essays.

Before submitting your essay, having a second set of eyes to catch any typos or grammatical errors is invaluable. If human help isn’t available, AI can step in to proofread or edit your work, offering instant feedback even under tight deadlines . Take a look at the different ways you can use AI for essay editing.

Ask AI to help you identify typos or grammatical errors

It’s easy for the human mind to skim over obvious typos and grammar errors. AI can help you identify these spelling mistakes and grammar issues so you can put some professional polish on your paper. If you’re aware of a specific issue that you struggle with in your essays, you can ask AI to proofread specifically on those errors. Copy and paste your essay into your favorite AI platform and try one of these prompts:

Can you identify any typos in this paper and explain why they are incorrect?
I often put commas in the wrong place. Can you identify any incorrect commas in my essay and tell me why they’re incorrect?
Can you help me identify any incorrect homophones in my essay?

Ask AI to help you refine your sentences

Writing clearly is important for all forms of writing, but it’s especially important for academic works. AI can help you edit your essays so that your sentences are easy to understand. Copy and paste your essay into an AI platform and try these prompts to refine its sentences:

Can you find passive sentences in my essay and explain how to rewrite them actively?
My teacher is a stickler for dangling modifiers . Can you point out any dangling modifiers in my essay?
Are there any sentence fragments in my essay?

Ask AI for style guide assistance

If your instructor has asked you to follow a specific style guide , they may deduct points if your essay doesn’t follow it. Try these prompts to get some essay editing help:

Can you review if book titles are correctly italicized according to the Chicago Manual of Style, and check for other style-specific issues?
My essay is supposed to follow MLA format. Can you identify any parts of my essay that don’t follow MLA format ?
How should I format quotes in APA format ?

Ask AI to fact-check your work

AI can help you identify incorrect facts that could impact your final grade. AI can also provide sources that you can use to back up your work. Try these prompts in your preferred AI platform to fact-check your work:

Are the biographical facts I included about Jane Austen in my essay correct?
Can you make sure all the dates that I listed in my essay are accurate?
Can you confirm that the citations in my essay are from peer-reviewed and reputable sources ?

Getting the best proofreading and editing results from AI

When you use AI to proofread an essay, you’ll get better results when you provide it with as much context about the essay as possible. For example, you should include your teacher’s essay instructions so that the AI tool knows what to look for. If the teacher gave you their grading rubric, you should also give it to the AI tool so that it can provide even stronger proofreading and editing recommendations.

While AI can significantly aid in proofreading and editing, remember to use it responsibly, especially in academic settings. If you’re interested in learning more about AI, see if you can use AI to draft an essay for you .
