How to write a thesis statement + examples

What is a thesis statement?

Is a thesis statement a question, how do you write a good thesis statement, how do i know if my thesis statement is good, examples of thesis statements, helpful resources on how to write a thesis statement, frequently asked questions about writing a thesis statement, related articles.

A thesis statement is the main argument of your paper or thesis.

The thesis statement is one of the most important elements of any piece of academic writing . It is a brief statement of your paper’s main argument. Essentially, you are stating what you will be writing about.

You can see your thesis statement as an answer to a question. While it also contains the question, it should really give an answer to the question with new information and not just restate or reiterate it.

Your thesis statement is part of your introduction. Learn more about how to write a good thesis introduction in our introduction guide .

A thesis statement is not a question. A statement must be arguable and provable through evidence and analysis. While your thesis might stem from a research question, it should be in the form of a statement.

Tip: A thesis statement is typically 1-2 sentences. For a longer project like a thesis, the statement may be several sentences or a paragraph.

A good thesis statement needs to do the following:

• Condense the main idea of your thesis into one or two sentences.
• Answer your project’s main research question.
• Clearly state your position in relation to the topic .
• Make an argument that requires support or evidence.

Once you have written down a thesis statement, check if it fulfills the following criteria:

• Your statement needs to be provable by evidence. As an argument, a thesis statement needs to be debatable.
• Your statement needs to be precise. Do not give away too much information in the thesis statement and do not load it with unnecessary information.
• Your statement cannot say that one solution is simply right or simply wrong as a matter of fact. You should draw upon verified facts to persuade the reader of your solution, but you cannot just declare something as right or wrong.

As previously mentioned, your thesis statement should answer a question.

If the question is:

What do you think the City of New York should do to reduce traffic congestion?

A good thesis statement restates the question and answers it:

In this paper, I will argue that the City of New York should focus on providing exclusive lanes for public transport and adaptive traffic signals to reduce traffic congestion by the year 2035.

Here is another example. If the question is:

How can we end poverty?

A good thesis statement should give more than one solution to the problem in question:

In this paper, I will argue that introducing universal basic income can help reduce poverty and positively impact the way we work.

• The Writing Center of the University of North Carolina has a list of questions to ask to see if your thesis is strong .

A thesis statement is part of the introduction of your paper. It is usually found in the first or second paragraph to let the reader know your research purpose from the beginning.

In general, a thesis statement should have one or two sentences. But the length really depends on the overall length of your project. Take a look at our guide about the length of thesis statements for more insight on this topic.

Here is a list of Thesis Statement Examples that will help you understand better how to write them.

Every good essay should include a thesis statement as part of its introduction, no matter the academic level. Of course, if you are a high school student you are not expected to have the same type of thesis as a PhD student.

Here is a great YouTube tutorial showing How To Write An Essay: Thesis Statements .

Developing a Thesis Statement

Many papers you write require developing a thesis statement. In this section you’ll learn what a thesis statement is and how to write one.

Keep in mind that not all papers require thesis statements . If in doubt, please consult your instructor for assistance.

What is a thesis statement?

A thesis statement . . .

• Makes an argumentative assertion about a topic; it states the conclusions that you have reached about your topic.
• Makes a promise to the reader about the scope, purpose, and direction of your paper.
• Is focused and specific enough to be “proven” within the boundaries of your paper.
• Is generally located near the end of the introduction ; sometimes, in a long paper, the thesis will be expressed in several sentences or in an entire paragraph.
• Identifies the relationships between the pieces of evidence that you are using to support your argument.

Not all papers require thesis statements! Ask your instructor if you’re in doubt whether you need one.

Identify a topic

Your topic is the subject about which you will write. Your assignment may suggest several ways of looking at a topic; or it may name a fairly general concept that you will explore or analyze in your paper.

Consider what your assignment asks you to do

Inform yourself about your topic, focus on one aspect of your topic, ask yourself whether your topic is worthy of your efforts, generate a topic from an assignment.

Below are some possible topics based on sample assignments.

Sample assignment 1

Analyze Spain’s neutrality in World War II.

Identified topic

Franco’s role in the diplomatic relationships between the Allies and the Axis

This topic avoids generalities such as “Spain” and “World War II,” addressing instead on Franco’s role (a specific aspect of “Spain”) and the diplomatic relations between the Allies and Axis (a specific aspect of World War II).

Sample assignment 2

Analyze one of Homer’s epic similes in the Iliad.

The relationship between the portrayal of warfare and the epic simile about Simoisius at 4.547-64.

This topic focuses on a single simile and relates it to a single aspect of the Iliad ( warfare being a major theme in that work).

Developing a Thesis Statement–Additional information

Your assignment may suggest several ways of looking at a topic, or it may name a fairly general concept that you will explore or analyze in your paper. You’ll want to read your assignment carefully, looking for key terms that you can use to focus your topic.

Sample assignment: Analyze Spain’s neutrality in World War II Key terms: analyze, Spain’s neutrality, World War II

After you’ve identified the key words in your topic, the next step is to read about them in several sources, or generate as much information as possible through an analysis of your topic. Obviously, the more material or knowledge you have, the more possibilities will be available for a strong argument. For the sample assignment above, you’ll want to look at books and articles on World War II in general, and Spain’s neutrality in particular.

As you consider your options, you must decide to focus on one aspect of your topic. This means that you cannot include everything you’ve learned about your topic, nor should you go off in several directions. If you end up covering too many different aspects of a topic, your paper will sprawl and be unconvincing in its argument, and it most likely will not fulfull the assignment requirements.

For the sample assignment above, both Spain’s neutrality and World War II are topics far too broad to explore in a paper. You may instead decide to focus on Franco’s role in the diplomatic relationships between the Allies and the Axis , which narrows down what aspects of Spain’s neutrality and World War II you want to discuss, as well as establishes a specific link between those two aspects.

Before you go too far, however, ask yourself whether your topic is worthy of your efforts. Try to avoid topics that already have too much written about them (i.e., “eating disorders and body image among adolescent women”) or that simply are not important (i.e. “why I like ice cream”). These topics may lead to a thesis that is either dry fact or a weird claim that cannot be supported. A good thesis falls somewhere between the two extremes. To arrive at this point, ask yourself what is new, interesting, contestable, or controversial about your topic.

As you work on your thesis, remember to keep the rest of your paper in mind at all times . Sometimes your thesis needs to evolve as you develop new insights, find new evidence, or take a different approach to your topic.

Derive a main point from topic

Once you have a topic, you will have to decide what the main point of your paper will be. This point, the “controlling idea,” becomes the core of your argument (thesis statement) and it is the unifying idea to which you will relate all your sub-theses. You can then turn this “controlling idea” into a purpose statement about what you intend to do in your paper.

Look for patterns in your evidence

Compose a purpose statement.

Consult the examples below for suggestions on how to look for patterns in your evidence and construct a purpose statement.

• Franco first tried to negotiate with the Axis
• Franco turned to the Allies when he couldn’t get some concessions that he wanted from the Axis

Possible conclusion:

Spain’s neutrality in WWII occurred for an entirely personal reason: Franco’s desire to preserve his own (and Spain’s) power.

Purpose statement

This paper will analyze Franco’s diplomacy during World War II to see how it contributed to Spain’s neutrality.

• The simile compares Simoisius to a tree, which is a peaceful, natural image.
• The tree in the simile is chopped down to make wheels for a chariot, which is an object used in warfare.

At first, the simile seems to take the reader away from the world of warfare, but we end up back in that world by the end.

This paper will analyze the way the simile about Simoisius at 4.547-64 moves in and out of the world of warfare.

Derive purpose statement from topic

To find out what your “controlling idea” is, you have to examine and evaluate your evidence . As you consider your evidence, you may notice patterns emerging, data repeated in more than one source, or facts that favor one view more than another. These patterns or data may then lead you to some conclusions about your topic and suggest that you can successfully argue for one idea better than another.

For instance, you might find out that Franco first tried to negotiate with the Axis, but when he couldn’t get some concessions that he wanted from them, he turned to the Allies. As you read more about Franco’s decisions, you may conclude that Spain’s neutrality in WWII occurred for an entirely personal reason: his desire to preserve his own (and Spain’s) power. Based on this conclusion, you can then write a trial thesis statement to help you decide what material belongs in your paper.

Sometimes you won’t be able to find a focus or identify your “spin” or specific argument immediately. Like some writers, you might begin with a purpose statement just to get yourself going. A purpose statement is one or more sentences that announce your topic and indicate the structure of the paper but do not state the conclusions you have drawn . Thus, you might begin with something like this:

• This paper will look at modern language to see if it reflects male dominance or female oppression.
• I plan to analyze anger and derision in offensive language to see if they represent a challenge of society’s authority.

At some point, you can turn a purpose statement into a thesis statement. As you think and write about your topic, you can restrict, clarify, and refine your argument, crafting your thesis statement to reflect your thinking.

As you work on your thesis, remember to keep the rest of your paper in mind at all times. Sometimes your thesis needs to evolve as you develop new insights, find new evidence, or take a different approach to your topic.

Compose a draft thesis statement

If you are writing a paper that will have an argumentative thesis and are having trouble getting started, the techniques in the table below may help you develop a temporary or “working” thesis statement.

Begin with a purpose statement that you will later turn into a thesis statement.

Assignment: Discuss the history of the Reform Party and explain its influence on the 1990 presidential and Congressional election.

Purpose Statement: This paper briefly sketches the history of the grassroots, conservative, Perot-led Reform Party and analyzes how it influenced the economic and social ideologies of the two mainstream parties.

Question-to-Assertion

If your assignment asks a specific question(s), turn the question(s) into an assertion and give reasons why it is true or reasons for your opinion.

Assignment : What do Aylmer and Rappaccini have to be proud of? Why aren’t they satisfied with these things? How does pride, as demonstrated in “The Birthmark” and “Rappaccini’s Daughter,” lead to unexpected problems?

Beginning thesis statement: Alymer and Rappaccinni are proud of their great knowledge; however, they are also very greedy and are driven to use their knowledge to alter some aspect of nature as a test of their ability. Evil results when they try to “play God.”

Write a sentence that summarizes the main idea of the essay you plan to write.

Main idea: The reason some toys succeed in the market is that they appeal to the consumers’ sense of the ridiculous and their basic desire to laugh at themselves.

Make a list of the ideas that you want to include; consider the ideas and try to group them.

• nature = peaceful
• war matériel = violent (competes with 1?)
• need for time and space to mourn the dead
• war is inescapable (competes with 3?)

Use a formula to arrive at a working thesis statement (you will revise this later).

• although most readers of _______ have argued that _______, closer examination shows that _______.
• _______ uses _______ and _____ to prove that ________.
• phenomenon x is a result of the combination of __________, __________, and _________.

What to keep in mind as you draft an initial thesis statement

Beginning statements obtained through the methods illustrated above can serve as a framework for planning or drafting your paper, but remember they’re not yet the specific, argumentative thesis you want for the final version of your paper. In fact, in its first stages, a thesis statement usually is ill-formed or rough and serves only as a planning tool.

As you write, you may discover evidence that does not fit your temporary or “working” thesis. Or you may reach deeper insights about your topic as you do more research, and you will find that your thesis statement has to be more complicated to match the evidence that you want to use.

You must be willing to reject or omit some evidence in order to keep your paper cohesive and your reader focused. Or you may have to revise your thesis to match the evidence and insights that you want to discuss. Read your draft carefully, noting the conclusions you have drawn and the major ideas which support or prove those conclusions. These will be the elements of your final thesis statement.

Sometimes you will not be able to identify these elements in your early drafts, but as you consider how your argument is developing and how your evidence supports your main idea, ask yourself, “ What is the main point that I want to prove/discuss? ” and “ How will I convince the reader that this is true? ” When you can answer these questions, then you can begin to refine the thesis statement.

Refine and polish the thesis statement

To get to your final thesis, you’ll need to refine your draft thesis so that it’s specific and arguable.

• Ask if your draft thesis addresses the assignment
• Question each part of your draft thesis
• Clarify vague phrases and assertions
• Investigate alternatives to your draft thesis

Consult the example below for suggestions on how to refine your draft thesis statement.

Sample Assignment

Choose an activity and define it as a symbol of American culture. Your essay should cause the reader to think critically about the society which produces and enjoys that activity.

• Ask The phenomenon of drive-in facilities is an interesting symbol of american culture, and these facilities demonstrate significant characteristics of our society.This statement does not fulfill the assignment because it does not require the reader to think critically about society.

Drive-ins are an interesting symbol of American culture because they represent Americans’ significant creativity and business ingenuity.

Among the types of drive-in facilities familiar during the twentieth century, drive-in movie theaters best represent American creativity, not merely because they were the forerunner of later drive-ins and drive-throughs, but because of their impact on our culture: they changed our relationship to the automobile, changed the way people experienced movies, and changed movie-going into a family activity.

While drive-in facilities such as those at fast-food establishments, banks, pharmacies, and dry cleaners symbolize America’s economic ingenuity, they also have affected our personal standards.

While drive-in facilities such as those at fast- food restaurants, banks, pharmacies, and dry cleaners symbolize (1) Americans’ business ingenuity, they also have contributed (2) to an increasing homogenization of our culture, (3) a willingness to depersonalize relationships with others, and (4) a tendency to sacrifice quality for convenience.

This statement is now specific and fulfills all parts of the assignment. This version, like any good thesis, is not self-evident; its points, 1-4, will have to be proven with evidence in the body of the paper. The numbers in this statement indicate the order in which the points will be presented. Depending on the length of the paper, there could be one paragraph for each numbered item or there could be blocks of paragraph for even pages for each one.

Complete the final thesis statement

The bottom line.

As you move through the process of crafting a thesis, you’ll need to remember four things:

• Context matters! Think about your course materials and lectures. Try to relate your thesis to the ideas your instructor is discussing.
• As you go through the process described in this section, always keep your assignment in mind . You will be more successful when your thesis (and paper) responds to the assignment than if it argues a semi-related idea.
• Your thesis statement should be precise, focused, and contestable ; it should predict the sub-theses or blocks of information that you will use to prove your argument.
• Make sure that you keep the rest of your paper in mind at all times. Change your thesis as your paper evolves, because you do not want your thesis to promise more than your paper actually delivers.

In the beginning, the thesis statement was a tool to help you sharpen your focus, limit material and establish the paper’s purpose. When your paper is finished, however, the thesis statement becomes a tool for your reader. It tells the reader what you have learned about your topic and what evidence led you to your conclusion. It keeps the reader on track–well able to understand and appreciate your argument.

Writing a Thesis Statement — Definition, Types, and Examples

What is a thesis statement?

A thesis statement is a single sentence that identifies the topic and purpose of a scholarly research paper or academic writing. A thesis statement directly or indirectly presents the main points of the paper. Information presented in the essay should tie directly back to the thesis.

Overall, a good thesis statement accomplishes the following:

Identifies the purpose of the essay

Expresses the writer's position/opinion

Lists the main supports (optional)

Briefly summarizes the writer's conclusion(s)

Establish if the essay is explanatory, argumentative, or analytical

People often confuse thesis statements with topic sentences , which start each body paragraph. Typically, the thesis statement is the final sentence in the introductory paragraph and acts as a “road map” for the rest of the paper.

Types of thesis statements

The three main types of thesis statements are explanatory, argumentative, and analytical.

Explanatory thesis statements are used in expository essays that focus solely on informing the reader. Papers with this type of thesis do not contain the writer's opinion, nor do they try to persuade the reader.

The three main branches of science taught in public schools include biology, chemistry, and physics.

Argumentative thesis statements identify the writer's position or point of view on a given topic. Argumentative essays persuade the reader to agree with the writer's stance. If the reader cannot agree or disagree with the claim in the thesis, then it is not argumentative.

Public schools should place more emphasis on the arts because they encourage creativity, help improve academic development, and provide a beneficial emotional outlet.

Analytical thesis statements are used in papers that analyze how or why something does what it does. These thesis statements identify what the writer is analyzing, the parts of the analysis, and the order of those parts.

An analysis of course requirements in public schools suggests access to more electives can increase graduation rates.

How to write a thesis statement

When writing a thesis, the following guidelines apply:

Step 1: Determine the type of paper (explanatory, argumentative, or analytical).

Step 2: Identify the topic, position/claim, and supports of the essay.

Step 3: Determine if the supports should be included within the thesis. Although they are considered optional, they might be required depending on the audience and purpose of the essay.

Step 4: Compose a sentence that includes the topic, position, and supports (optional). While a thesis statement can be more than one sentence, it should not exceed two.

Step 5: Place the thesis statement at the end of the introductory paragraph(s). Placing it at the end of the introduction and before the supports allows the reader to focus on the paper’s main purpose.

Thesis statement examples

The following examples highlight each type of thesis statement.

Topic: Alternative Energy Sources

Explanatory Thesis: Alternative energy sources that can supplement the use of fossil fuels include solar, wind, and geothermal.

Argumentative Thesis: To combat reliance on foreign sources of fossil fuels, the United States would benefit from focusing on alternative energy options.

Analytical Thesis: Analysis suggests that replacing fossil fuels with alternative energy sources could negatively impact the economy.

Topic: Social Media

Explanatory Thesis: Three of the first platforms that influenced the world of social media include Facebook, Twitter, and Instagram.

Argumentative Thesis: Social media negatively influences society as it increases opportunities for cyberbullying, limits face-to-face interactions, and creates unrealistic expectations.

Analytical Thesis: An analysis of the use of social media suggests itis irrevocably harming the development of teenagers.

Topic: Standardized Testing

Explanatory Thesis: Standardized tests such as the ACT and SAT play a limited role in influencing college acceptance.

Argumentative Thesis: Standardized testing should not be required because it increases anxiety, does not measure progress, and cannot predict future success.

Analytical Thesis: Analysis suggests that standardized testing in elementary and high school negatively impacts students' academic success.

Writing a Paper: Thesis Statements

Basics of thesis statements.

The thesis statement is the brief articulation of your paper's central argument and purpose. You might hear it referred to as simply a "thesis." Every scholarly paper should have a thesis statement, and strong thesis statements are concise, specific, and arguable. Concise means the thesis is short: perhaps one or two sentences for a shorter paper. Specific means the thesis deals with a narrow and focused topic, appropriate to the paper's length. Arguable means that a scholar in your field could disagree (or perhaps already has!).

Strong thesis statements address specific intellectual questions, have clear positions, and use a structure that reflects the overall structure of the paper. Read on to learn more about constructing a strong thesis statement.

Being Specific

This thesis statement has no specific argument:

Needs Improvement: In this essay, I will examine two scholarly articles to find similarities and differences.

This statement is concise, but it is neither specific nor arguable—a reader might wonder, "Which scholarly articles? What is the topic of this paper? What field is the author writing in?" Additionally, the purpose of the paper—to "examine…to find similarities and differences" is not of a scholarly level. Identifying similarities and differences is a good first step, but strong academic argument goes further, analyzing what those similarities and differences might mean or imply.

Better: In this essay, I will argue that Bowler's (2003) autocratic management style, when coupled with Smith's (2007) theory of social cognition, can reduce the expenses associated with employee turnover.

The new revision here is still concise, as well as specific and arguable.  We can see that it is specific because the writer is mentioning (a) concrete ideas and (b) exact authors.  We can also gather the field (business) and the topic (management and employee turnover). The statement is arguable because the student goes beyond merely comparing; he or she draws conclusions from that comparison ("can reduce the expenses associated with employee turnover").

Making a Unique Argument

This thesis draft repeats the language of the writing prompt without making a unique argument:

Needs Improvement: The purpose of this essay is to monitor, assess, and evaluate an educational program for its strengths and weaknesses. Then, I will provide suggestions for improvement.

You can see here that the student has simply stated the paper's assignment, without articulating specifically how he or she will address it. The student can correct this error simply by phrasing the thesis statement as a specific answer to the assignment prompt.

Better: Through a series of student interviews, I found that Kennedy High School's antibullying program was ineffective. In order to address issues of conflict between students, I argue that Kennedy High School should embrace policies outlined by the California Department of Education (2010).

Words like "ineffective" and "argue" show here that the student has clearly thought through the assignment and analyzed the material; he or she is putting forth a specific and debatable position. The concrete information ("student interviews," "antibullying") further prepares the reader for the body of the paper and demonstrates how the student has addressed the assignment prompt without just restating that language.

Creating a Debate

This thesis statement includes only obvious fact or plot summary instead of argument:

Needs Improvement: Leadership is an important quality in nurse educators.

A good strategy to determine if your thesis statement is too broad (and therefore, not arguable) is to ask yourself, "Would a scholar in my field disagree with this point?" Here, we can see easily that no scholar is likely to argue that leadership is an unimportant quality in nurse educators.  The student needs to come up with a more arguable claim, and probably a narrower one; remember that a short paper needs a more focused topic than a dissertation.

Better: Roderick's (2009) theory of participatory leadership  is particularly appropriate to nurse educators working within the emergency medicine field, where students benefit most from collegial and kinesthetic learning.

Here, the student has identified a particular type of leadership ("participatory leadership"), narrowing the topic, and has made an arguable claim (this type of leadership is "appropriate" to a specific type of nurse educator). Conceivably, a scholar in the nursing field might disagree with this approach. The student's paper can now proceed, providing specific pieces of evidence to support the arguable central claim.

Choosing the Right Words

This thesis statement uses large or scholarly-sounding words that have no real substance:

Needs Improvement: Scholars should work to seize metacognitive outcomes by harnessing discipline-based networks to empower collaborative infrastructures.

There are many words in this sentence that may be buzzwords in the student's field or key terms taken from other texts, but together they do not communicate a clear, specific meaning. Sometimes students think scholarly writing means constructing complex sentences using special language, but actually it's usually a stronger choice to write clear, simple sentences. When in doubt, remember that your ideas should be complex, not your sentence structure.

Better: Ecologists should work to educate the U.S. public on conservation methods by making use of local and national green organizations to create a widespread communication plan.

Notice in the revision that the field is now clear (ecology), and the language has been made much more field-specific ("conservation methods," "green organizations"), so the reader is able to see concretely the ideas the student is communicating.

Leaving Room for Discussion

This thesis statement is not capable of development or advancement in the paper:

Needs Improvement: There are always alternatives to illegal drug use.

This sample thesis statement makes a claim, but it is not a claim that will sustain extended discussion. This claim is the type of claim that might be appropriate for the conclusion of a paper, but in the beginning of the paper, the student is left with nowhere to go. What further points can be made? If there are "always alternatives" to the problem the student is identifying, then why bother developing a paper around that claim? Ideally, a thesis statement should be complex enough to explore over the length of the entire paper.

Better: The most effective treatment plan for methamphetamine addiction may be a combination of pharmacological and cognitive therapy, as argued by Baker (2008), Smith (2009), and Xavier (2011).

In the revised thesis, you can see the student make a specific, debatable claim that has the potential to generate several pages' worth of discussion. When drafting a thesis statement, think about the questions your thesis statement will generate: What follow-up inquiries might a reader have? In the first example, there are almost no additional questions implied, but the revised example allows for a good deal more exploration.

Thesis Mad Libs

If you are having trouble getting started, try using the models below to generate a rough model of a thesis statement! These models are intended for drafting purposes only and should not appear in your final work.

• In this essay, I argue ____, using ______ to assert _____.
• While scholars have often argued ______, I argue______, because_______.
• Through an analysis of ______, I argue ______, which is important because_______.

Words to Avoid and to Embrace

When drafting your thesis statement, avoid words like explore, investigate, learn, compile, summarize , and explain to describe the main purpose of your paper. These words imply a paper that summarizes or "reports," rather than synthesizing and analyzing.

Instead of the terms above, try words like argue, critique, question , and interrogate . These more analytical words may help you begin strongly, by articulating a specific, critical, scholarly position.

Thesis Statement

Definition of thesis statement.

A thesis statement is a statement that occurs at the end of the introduction , after the background information on the topic. The thesis statement is connected with the background information through a transition , which could be a full sentence , or a simple transition word, such as therefore, because, but etc.

The thesis statement is called the “heart of the essay .” The idea of an essay without a thesis statement is akin to a body without its heart. It also is called the “central point” or the “core” of an essay. It is comprised of evidences that the writer uses to elaborate on his topic further. Each of these evidences is then elaborated and discussed in the body paragraphs .

If there are three body paragraphs, the thesis statement must have three evidences, and should it have more than three body paragraphs, may be additional evidences. In argumentative essays, three evidences support the topic, while the fourth evidence is against it. The same is the case of persuasive essays. This applies to five-paragraph essays, but in case of a longer essay, the thesis statement could make use of more than one sentence.

There is a slight controversy over the placement of a thesis statement. Some writers and professors argue that it could be placed in the first paragraph at the end, while others feel that, in longer essays, it is not possible to give background information in just one paragraph. As background information takes two or three paragraphs, the thesis statement is kept slightly larger, having two or three sentences, and is placed at the end of the second or third paragraph. However, in a five-paragraph essay, the thesis statement is always placed at the end of the introduction, after the background information.

Qualities of a Good Thesis Statement

• It must have evidences.
• It should be interesting.
• It should be limited.
• It should be manageable.
• It should be researchable.

Difference Between a Thesis Statement and Topic

Sometimes students confuse a thesis statement with a topic, mistaking the thesis statement as the very topic of the essay they are going to read. However, it must be kept in mind that a thesis statement is not a topic, but a brief explanation of the topic in a way that sets the direction of the essay. It predicts the path the essay will take, and tells readers how the essay is going to be organized, and what each part contains.

The topic, however, is a general idea of the essay. It is a specific topic, which has been organized by the thesis statement. The thesis statement in turn elaborates evidences to support to the topic.

Examples of Good and Bad Thesis Statements

• Bad Thesis Statement – “Social media is proving a good marketing tool.”
• Good Thesis Statement – “Social media is proving to be, not only a better marketing tool, but also a source of advertisement for short and medium enterprises intending to expand their consumer base.”

Examples of Thesis Statements in Literature

Example #1:  dream on (by mark krikorian in national review online ).

“The core principal behind this amnesty proposal is that it is amid at those who have grown up here and are, psychologically and emotionally, Americans.”

This is the first sentence of the second paragraph. The second sentence further elaborates this thesis. It is placed in the second paragraph because the first paragraph introduces the controversial DREAM Act. As the writer is going to argue against the bill, he has stated his argument as to why he is going to oppose it. This is a very compact thesis statement with various implicit counter arguments.

Example #2: Editorial (by The Washington Post)

“There is no doubt that the attacks profoundly affected our country’s policy, politics, economics, society and even collective psychology. Moreover, in addition to sharing the immediate experience of September 9/11, Americans have dealt with its consequences in the years since.”

This is the best thesis statement with clear evidences in it. It is not as complicated as other thesis statements usually are.

Example #3: I Have a Dream (by Martin Luther King)

“In a sense we’ve come to our nation’s capital to cash a check. When the architects of our republic wrote the magnificent words of the Constitution and the Declaration of Independence, they were signing a promissory note to which every American was to fall heir. This note was a promise that all men, yes, black men as well as white men, would be guaranteed the ‘unalienable Rights’ of ‘Life, Liberty and the pursuit of Happiness.’ It is obvious today that America has defaulted on this promissory note, insofar as her citizens of color are concerned. Instead of honoring this sacred obligation, America has given the Negro people a bad check, a check which has come back marked ‘insufficient funds’.”

This is one of the best examples of long thesis statements. It highlights what Martin Luther King is going to speak about. It comes after three paragraphs of background information.

Function of Thesis Statement

A good thesis statement is the heart of an essay. It gives a gist of the thoughts a writer expresses in his essay. It determines the shape of the essay, predicts its content, and foreshadows its events. It narrates the whole story in just one sentence, provided the essay is a short one. Without a thesis statement, an essay is just a written piece, not an organized and well-connected essay

More About Thesis Statement

What is a thesis statement .

In academic writing, a thesis statement is generally a sentence or two that summarizes the main point that an essay, research paper, or speech is making. It is typically located at the end of the introductory paragraph(s).

Thesis statements are kind of like roadmaps, laying out for the reader/listener where the writer/speaker is headed (argument) and how they are going to get there (evidence).

The thesis statement is widely taught in the humanities, especially in English classes in high school and college, to teach students how to make persuasive arguments that cite and analyze evidence and examples researched from literary, historical, or other texts.

Why is a thesis statement important in an essay?

Thesis comes from a Greek word that literally means “a setting down.” In the 300s BC, Aristotle defined thesis as when a philosopher puts forth a new idea that conflicts with general opinion.

Fast forward to today, when we use thesis to mean a “proposition” or “argument” one formally presents and defends. In academic settings, a thesis can be short for a thesis statement (our focus here) in an essay or shorter research paper. It can also be used for those much, much longer dissertations graduate students research, write, and defend for their degree (e.g., master’s thesis or doctoral thesis ).

Let’s look at statement real quick. It is a declaration or assertion. Sound redundant? The idea is that a thesis statement is the point in a paper or presentation that explicitly states the thesis. Usually in a sentence or two, the thesis statement summarizes the argument that’s going to be developed in the evidence and examples to come.

So, a thesis statement is just a sentence that gets the main point across. But, learning how to write these ain’t easy. That’s why educators, especially in English classes in high school and college, spend a lot of time teaching students how to craft effective thesis statements.

Why? Because in school, work, and life, we have to persuade people of our ideas and our point of view. These ideas might concern an analysis of literature or history, like a play by Shakespeare or a moment in the Civil Rights Movement. Or, these ideas might be a call to action, such as eating a certain diet or pursuing a business strategy.

How to write a thesis statement

There are many ways to make an effective thesis statement , but here are some general tips to follow.

So, let’s say you read a text, Shakespeare’s Twelfth Night , or researched a topic, the health benefits of kale. Then you formed an opinion about it—a claim you want to make about it and why others should care. You found evidence—quotes, examples, facts, statistics—in your resources that you think back up your argument. Your thesis statement brings all these together: point of view , evidence , and significance . It lays out where the entire paper or presentation is going, which is why educators often liken it to a roadmap .

Here’s an example:

Kale is good for you because it is nutrient-dense, cancer-fighting, and loaded with antioxidants.

The argument here—which a first-year high-schooler might make in a persuasive essay—is that “kale is good for you” (despite how some think it tastes). The claims it’s using to back up this assertion are that it’s 1) “nutrient-dense”; 2) “cancer-fighting”; and 3) “loaded with antioxidants.” The reader can expect that the rest of the essay will develop these claims, that is, cite and analyze evidence for them.

Here’s a thesis statement for a literary analysis of Shakespeare’s Twelfth Night. This resembles more of a college-level example:

Shakespeare’s Twelfth Night suggests that, when women do not reciprocate a man’s love, they are unjustly made out to be sexually deviant. This is illustrated in how the character Olivia is condemned as asexual because of her rejection of Duke Orsino.

Note how this thesis statement makes its claim in two sentences. Its argument centers on how women characters are vilified when they reject a man, and its evidence will be interactions between characters in Shakespeare’s play.

What are real-life examples of thesis statement ?

The term thesis statement is generally used by teachers and students in junior high, high school, and college, especially in English, Social Studies, and other classes in the humanities.

Okay so I rewrote my thesis statement! It’s a wee bit more vague but still a good direction a think. It’s more open so I can talk about more things and add more evidence. Wrote out an in-depth plan and then my brain crapped out. So I’m going to bed! Tomorrow is the day! — 🎃Unpaid Bills🎃 //Chaela (@Cierafire) August 14, 2019

Writing an explanatory essay in phases: thesis statement, body paragraph, concluding statement. Peer conversations to identify text evidence to support our thesis. pic.twitter.com/b6fdgx8rkD — Cheyenne England (@MsEnglandReads) August 7, 2019

The thesis statement is taught in what’s called the five-paragraph essay (or theme). This essay has an introduction which “funnels into” the thesis statement, including three reasons backing up the main argument. The next three paragraphs develop each of these claims, respectively, citing evidence and examples, such as literary texts, historical documents, or scientific reports. The final paragraph, the conclusion, restates the thesis statement and summarizes the paper and its broader significance.

Even after we are no longer in the classroom, people continue to reference thesis statements. While “real-life” thesis statements may not be as formal as the ones seen in five-paragraph essays, having a thesis statement —a point, a position, or a theory of the case—is considered informative, persuasive, and valuable in work, in the community, and in our personal lives.

The thesis statement is so widely taught and familiar that sometimes people joke about them. On social media, for instance, people may humorously end a post with “In this essay, I will …” when expressing a deeply felt but ultimately low-stakes opinion on some popular topic. The phrase In this essay, I will alludes to the signposting language some people use in their thesis statements.

What is a thesis | A Complete Guide with Examples

Table of Contents

A thesis is a comprehensive academic paper based on your original research that presents new findings, arguments, and ideas of your study. It’s typically submitted at the end of your master’s degree or as a capstone of your bachelor’s degree.

However, writing a thesis can be laborious, especially for beginners. From the initial challenge of pinpointing a compelling research topic to organizing and presenting findings, the process is filled with potential pitfalls.

Therefore, to help you, this guide talks about what is a thesis. Additionally, it offers revelations and methodologies to transform it from an overwhelming task to a manageable and rewarding academic milestone.

What is a thesis?

A thesis is an in-depth research study that identifies a particular topic of inquiry and presents a clear argument or perspective about that topic using evidence and logic.

Writing a thesis showcases your ability of critical thinking, gathering evidence, and making a compelling argument. Integral to these competencies is thorough research, which not only fortifies your propositions but also confers credibility to your entire study.

Furthermore, there's another phenomenon you might often confuse with the thesis: the ' working thesis .' However, they aren't similar and shouldn't be used interchangeably.

A working thesis, often referred to as a preliminary or tentative thesis, is an initial version of your thesis statement. It serves as a draft or a starting point that guides your research in its early stages.

As you research more and gather more evidence, your initial thesis (aka working thesis) might change. It's like a starting point that can be adjusted as you learn more. It's normal for your main topic to change a few times before you finalize it.

While a thesis identifies and provides an overarching argument, the key to clearly communicating the central point of that argument lies in writing a strong thesis statement.

What is a thesis statement?

A strong thesis statement (aka thesis sentence) is a concise summary of the main argument or claim of the paper. It serves as a critical anchor in any academic work, succinctly encapsulating the primary argument or main idea of the entire paper.

Typically found within the introductory section, a strong thesis statement acts as a roadmap of your thesis, directing readers through your arguments and findings. By delineating the core focus of your investigation, it offers readers an immediate understanding of the context and the gravity of your study.

Furthermore, an effectively crafted thesis statement can set forth the boundaries of your research, helping readers anticipate the specific areas of inquiry you are addressing.

Different types of thesis statements

A good thesis statement is clear, specific, and arguable. Therefore, it is necessary for you to choose the right type of thesis statement for your academic papers.

Thesis statements can be classified based on their purpose and structure. Here are the primary types of thesis statements:

Argumentative (or Persuasive) thesis statement

Purpose : To convince the reader of a particular stance or point of view by presenting evidence and formulating a compelling argument.

Example : Reducing plastic use in daily life is essential for environmental health.

Analytical thesis statement

Purpose : To break down an idea or issue into its components and evaluate it.

Example : By examining the long-term effects, social implications, and economic impact of climate change, it becomes evident that immediate global action is necessary.

Expository (or Descriptive) thesis statement

Purpose : To explain a topic or subject to the reader.

Example : The Great Depression, spanning the 1930s, was a severe worldwide economic downturn triggered by a stock market crash, bank failures, and reduced consumer spending.

Cause and effect thesis statement

Purpose : To demonstrate a cause and its resulting effect.

Example : Overuse of smartphones can lead to impaired sleep patterns, reduced face-to-face social interactions, and increased levels of anxiety.

Compare and contrast thesis statement

Purpose : To highlight similarities and differences between two subjects.

Example : "While both novels '1984' and 'Brave New World' delve into dystopian futures, they differ in their portrayal of individual freedom, societal control, and the role of technology."

When you write a thesis statement , it's important to ensure clarity and precision, so the reader immediately understands the central focus of your work.

What is the difference between a thesis and a thesis statement?

While both terms are frequently used interchangeably, they have distinct meanings.

A thesis refers to the entire research document, encompassing all its chapters and sections. In contrast, a thesis statement is a brief assertion that encapsulates the central argument of the research.

Here’s an in-depth differentiation table of a thesis and a thesis statement.

Now, to craft a compelling thesis, it's crucial to adhere to a specific structure. Let’s break down these essential components that make up a thesis structure

15 components of a thesis structure

Navigating a thesis can be daunting. However, understanding its structure can make the process more manageable.

Here are the key components or different sections of a thesis structure:

Your thesis begins with the title page. It's not just a formality but the gateway to your research.

Here, you'll prominently display the necessary information about you (the author) and your institutional details.

• Title of your thesis
• Your full name
• Your department
• Your institution and degree program
• Your submission date
• Your Supervisor's name (in some cases)
• Your Department or faculty (in some cases)
• Your University's logo (in some cases)
• Your Student ID (in some cases)

In a concise manner, you'll have to summarize the critical aspects of your research in typically no more than 200-300 words.

This includes the problem statement, methodology, key findings, and conclusions. For many, the abstract will determine if they delve deeper into your work, so ensure it's clear and compelling.

Acknowledgments

Research is rarely a solitary endeavor. In the acknowledgments section, you have the chance to express gratitude to those who've supported your journey.

This might include advisors, peers, institutions, or even personal sources of inspiration and support. It's a personal touch, reflecting the humanity behind the academic rigor.

Table of contents

A roadmap for your readers, the table of contents lists the chapters, sections, and subsections of your thesis.

By providing page numbers, you allow readers to navigate your work easily, jumping to sections that pique their interest.

List of figures and tables

Research often involves data, and presenting this data visually can enhance understanding. This section provides an organized listing of all figures and tables in your thesis.

It's a visual index, ensuring that readers can quickly locate and reference your graphical data.

Introduction

Here's where you introduce your research topic, articulate the research question or objective, and outline the significance of your study.

• Present the research topic : Clearly articulate the central theme or subject of your research.
• Background information : Ground your research topic, providing any necessary context or background information your readers might need to understand the significance of your study.
• Define the scope : Clearly delineate the boundaries of your research, indicating what will and won't be covered.
• Literature review : Introduce any relevant existing research on your topic, situating your work within the broader academic conversation and highlighting where your research fits in.
• State the research Question(s) or objective(s) : Clearly articulate the primary questions or objectives your research aims to address.
• Outline the study's structure : Give a brief overview of how the subsequent sections of your work will unfold, guiding your readers through the journey ahead.

The introduction should captivate your readers, making them eager to delve deeper into your research journey.

Literature review section

Your study correlates with existing research. Therefore, in the literature review section, you'll engage in a dialogue with existing knowledge, highlighting relevant studies, theories, and findings.

It's here that you identify gaps in the current knowledge, positioning your research as a bridge to new insights.

To streamline this process, consider leveraging AI tools. For example, the SciSpace literature review tool enables you to efficiently explore and delve into research papers, simplifying your literature review journey.

Methodology

In the research methodology section, you’ll detail the tools, techniques, and processes you employed to gather and analyze data. This section will inform the readers about how you approached your research questions and ensures the reproducibility of your study.

Here's a breakdown of what it should encompass:

• Research Design : Describe the overall structure and approach of your research. Are you conducting a qualitative study with in-depth interviews? Or is it a quantitative study using statistical analysis? Perhaps it's a mixed-methods approach?
• Data Collection : Detail the methods you used to gather data. This could include surveys, experiments, observations, interviews, archival research, etc. Mention where you sourced your data, the duration of data collection, and any tools or instruments used.
• Sampling : If applicable, explain how you selected participants or data sources for your study. Discuss the size of your sample and the rationale behind choosing it.
• Data Analysis : Describe the techniques and tools you used to process and analyze the data. This could range from statistical tests in quantitative research to thematic analysis in qualitative research.
• Validity and Reliability : Address the steps you took to ensure the validity and reliability of your findings to ensure that your results are both accurate and consistent.
• Ethical Considerations : Highlight any ethical issues related to your research and the measures you took to address them, including — informed consent, confidentiality, and data storage and protection measures.

Moreover, different research questions necessitate different types of methodologies. For instance:

• Experimental methodology : Often used in sciences, this involves a controlled experiment to discern causality.
• Qualitative methodology : Employed when exploring patterns or phenomena without numerical data. Methods can include interviews, focus groups, or content analysis.
• Quantitative methodology : Concerned with measurable data and often involves statistical analysis. Surveys and structured observations are common tools here.
• Mixed methods : As the name implies, this combines both qualitative and quantitative methodologies.

The Methodology section isn’t just about detailing the methods but also justifying why they were chosen. The appropriateness of the methods in addressing your research question can significantly impact the credibility of your findings.

Results (or Findings)

This section presents the outcomes of your research. It's crucial to note that the nature of your results may vary; they could be quantitative, qualitative, or a mix of both.

Quantitative results often present statistical data, showcasing measurable outcomes, and they benefit from tables, graphs, and figures to depict these data points.

Qualitative results , on the other hand, might delve into patterns, themes, or narratives derived from non-numerical data, such as interviews or observations.

Regardless of the nature of your results, clarity is essential. This section is purely about presenting the data without offering interpretations — that comes later in the discussion.

In the discussion section, the raw data transforms into valuable insights.

Start by revisiting your research question and contrast it with the findings. How do your results expand, constrict, or challenge current academic conversations?

Dive into the intricacies of the data, guiding the reader through its implications. Detail potential limitations transparently, signaling your awareness of the research's boundaries. This is where your academic voice should be resonant and confident.

Practical implications (Recommendation) section

Based on the insights derived from your research, this section provides actionable suggestions or proposed solutions.

Whether aimed at industry professionals or the general public, recommendations translate your academic findings into potential real-world actions. They help readers understand the practical implications of your work and how it can be applied to effect change or improvement in a given field.

When crafting recommendations, it's essential to ensure they're feasible and rooted in the evidence provided by your research. They shouldn't merely be aspirational but should offer a clear path forward, grounded in your findings.

The conclusion provides closure to your research narrative.

It's not merely a recap but a synthesis of your main findings and their broader implications. Reconnect with the research questions or hypotheses posited at the beginning, offering clear answers based on your findings.

Reflect on the broader contributions of your study, considering its impact on the academic community and potential real-world applications.

Lastly, the conclusion should leave your readers with a clear understanding of the value and impact of your study.

References (or Bibliography)

Every theory you've expounded upon, every data point you've cited, and every methodological precedent you've followed finds its acknowledgment here.

In references, it's crucial to ensure meticulous consistency in formatting, mirroring the specific guidelines of the chosen citation style .

Proper referencing helps to avoid plagiarism , gives credit to original ideas, and allows readers to explore topics of interest. Moreover, it situates your work within the continuum of academic knowledge.

To properly cite the sources used in the study, you can rely on online citation generator tools  to generate accurate citations!

Here’s more on how you can cite your sources.

Often, the depth of research produces a wealth of material that, while crucial, can make the core content of the thesis cumbersome. The appendix is where you mention extra information that supports your research but isn't central to the main text.

Whether it's raw datasets, detailed procedural methodologies, extended case studies, or any other ancillary material, the appendices ensure that these elements are archived for reference without breaking the main narrative's flow.

For thorough researchers and readers keen on meticulous details, the appendices provide a treasure trove of insights.

Glossary (optional)

In academics, specialized terminologies, and jargon are inevitable. However, not every reader is versed in every term.

The glossary, while optional, is a critical tool for accessibility. It's a bridge ensuring that even readers from outside the discipline can access, understand, and appreciate your work.

By defining complex terms and providing context, you're inviting a wider audience to engage with your research, enhancing its reach and impact.

Remember, while these components provide a structured framework, the essence of your thesis lies in the originality of your ideas, the rigor of your research, and the clarity of your presentation.

As you craft each section, keep your readers in mind, ensuring that your passion and dedication shine through every page.

Thesis examples

To further elucidate the concept of a thesis, here are illustrative examples from various fields:

Example 1 (History): Abolition, Africans, and Abstraction: the Influence of the ‘Noble Savage’ on British and French Antislavery Thought, 1787-1807 by Suchait Kahlon.

Example 2 (Climate Dynamics): Influence of external forcings on abrupt millennial-scale climate changes: a statistical modelling study by Takahito Mitsui · Michel Crucifix

Ensure to use this checklist to leave no ground for doubt or missed information in your thesis.

After writing your thesis, the next step is to discuss and defend your findings verbally in front of a knowledgeable panel. You’ve to be well prepared as your professors may grade your presentation abilities.

Preparing your thesis defense

A thesis defense, also known as "defending the thesis," is the culmination of a scholar's research journey. It's the final frontier, where you’ll present their findings and face scrutiny from a panel of experts.

Typically, the defense involves a public presentation where you’ll have to outline your study, followed by a question-and-answer session with a committee of experts. This committee assesses the validity, originality, and significance of the research.

The defense serves as a rite of passage for scholars. It's an opportunity to showcase expertise, address criticisms, and refine arguments. A successful defense not only validates the research but also establishes your authority as a researcher in your field.

Here’s how you can effectively prepare for your thesis defense .

Now, having touched upon the process of defending a thesis, it's worth noting that scholarly work can take various forms, depending on academic and regional practices.

One such form, often paralleled with the thesis, is the 'dissertation.' But what differentiates the two?

Dissertation vs. Thesis

Often used interchangeably in casual discourse, they refer to distinct research projects undertaken at different levels of higher education.

To the uninitiated, understanding their meaning might be elusive. So, let's demystify these terms and delve into their core differences.

Here's a table differentiating between the two.

Wrapping up

From understanding the foundational concept of a thesis to navigating its various components, differentiating it from a dissertation, and recognizing the importance of proper citation — this guide covers it all.

As scholars and readers, understanding these nuances not only aids in academic pursuits but also fosters a deeper appreciation for the relentless quest for knowledge that drives academia.

It’s important to remember that every thesis is a testament to curiosity, dedication, and the indomitable spirit of discovery.

Good luck with your thesis writing!

Frequently Asked Questions

A thesis typically ranges between 40-80 pages, but its length can vary based on the research topic, institution guidelines, and level of study.

A PhD thesis usually spans 200-300 pages, though this can vary based on the discipline, complexity of the research, and institutional requirements.

To identify a thesis topic, consider current trends in your field, gaps in existing literature, personal interests, and discussions with advisors or mentors. Additionally, reviewing related journals and conference proceedings can provide insights into potential areas of exploration.

The conceptual framework is often situated in the literature review or theoretical framework section of a thesis. It helps set the stage by providing the context, defining key concepts, and explaining the relationships between variables.

A thesis statement should be concise, clear, and specific. It should state the main argument or point of your research. Start by pinpointing the central question or issue your research addresses, then condense that into a single statement, ensuring it reflects the essence of your paper.

Tips and Examples for Writing Thesis Statements

Welcome to the Purdue OWL

Tips for Writing Your Thesis Statement

1. Determine what kind of paper you are writing:

• An analytical paper breaks down an issue or an idea into its component parts, evaluates the issue or idea, and presents this breakdown and evaluation to the audience.
• An expository (explanatory) paper explains something to the audience.
• An argumentative paper makes a claim about a topic and justifies this claim with specific evidence. The claim could be an opinion, a policy proposal, an evaluation, a cause-and-effect statement, or an interpretation. The goal of the argumentative paper is to convince the audience that the claim is true based on the evidence provided.

If you are writing a text that does not fall under these three categories (e.g., a narrative), a thesis statement somewhere in the first paragraph could still be helpful to your reader.

2. Your thesis statement should be specific—it should cover only what you will discuss in your paper and should be supported with specific evidence.

3. The thesis statement usually appears at the end of the first paragraph of a paper.

4. Your topic may change as you write, so you may need to revise your thesis statement to reflect exactly what you have discussed in the paper.

Thesis Statement Examples

Example of an analytical thesis statement:

The paper that follows should:

• Explain the analysis of the college admission process
• Explain the challenge facing admissions counselors

Example of an expository (explanatory) thesis statement:

• Explain how students spend their time studying, attending class, and socializing with peers

Example of an argumentative thesis statement:

• Present an argument and give evidence to support the claim that students should pursue community projects before entering college

FAQ - English & Grammar

What Is a Thesis Statement? Definition and Examples.

What is a thesis statement.

A thesis statement is a declaration of one or two sentences that gives the topic and purpose of an essay or speech. More specifically, it provides information to the audience about what the author/speaker intends to prove or declare, with specific discussion points. The thesis statement is usually placed toward the end of the introductory paragraph.

What Should a Thesis Statement Include?

Regardless of the type of paper or speech you’re writing, a strong thesis statement should include the following five elements:

·          Restatement of the Topic : You should state the main topic of your dissertation before your thesis statement, usually within the first or second sentence. The proceeding thesis statement should then refer back to this topic.

·          Declaration of Your Position : After restating the main topic of your essay, declare your personal viewpoint on the issue.

·          An Opposing Viewpoint : Many topics are quite controversial, such as abortion, the death penalty, and vaccines, and can include a myriad of perspectives. An effective thesis statement is one that offers an opposing viewpoint, even if the main topic isn’t debatable. For example, if the main topic of your essay is about how pollution is harmful to the environment, your thesis might give your personal opinions of the worst effects of pollution. These opinions are what will have opposing viewpoints.

·          Reasons to Support Your Stance : For a strong thesis, it’s not enough to simply state what you believe; you have to provide reasons for that belief. In a standard five-paragraph essay, having at least three reasons/discussion points is sufficient to support your thesis.

·          Evidence to Support Your Stance : Whether your intentions are to persuade, inform, entertain, or educate your audience, make sure your thesis includes evidence from credible sources to support your discussion points.  

Structuring Your Thesis Statement

When writing a thesis statement for the first time, it’s important to understand how to structure it. Answering the following questions may help. Use your responses to write your statement, keeping each component in the same order as your answers. Keep in mind that #2 and 3 can be reversed, as in the examples in the next section.

1.        What is your essay about?

2.        What opinion/belief do you wish to convey on this topic?

3.        What is one other belief (preferably a common one) on this topic?

4.        Why do you hold your beliefs on the topic (give three reasons)?

5.        What evidence do you have to support each of your reasons?

Thesis Statement Examples

The following is a list of topics that are commonly selected for high school or college essays, as well as an example thesis statement for each topic. Each of these examples contains a mention of the topic, a reference to an opposing viewpoint, a declaration of the writer’s personal beliefs on the issue, and a list of reasons to support the beliefs.

Please note, these statements are intended for example purposes only and may or may not include actual facts about the topics.

·          Nationwide Legalization of Marijuana : While there are some benefits of marijuana, this drug should be illegal in all 50 states because it’s addictive, it can lead to psychotic disorders, and legalizing it can pose a risk for contamination. 

·          Mask Mandates : Despite the claims of masks being used as a preventive measure against COVID-19, mask mandates should be banned worldwide because they infringe on personal rights, masks can be dangerous, and masks are proven to be ineffective in preventing infection.

·          The Ketogenic Diet : Although the ketogenic diet is rising in popularity, it should not be used as a long-term means of weight loss/maintenance because there are negative side effects, carbohydrates boost the release of serotine, and you’re more likely to eat an unhealthy amount of red meat.

·          Universal Healthcare : The Unites States does not currently offer universal healthcare, but it should because doing so would increase the average lifespan, improve overall public health, and create more jobs.

·          Vegetarianism : While most Americans eat meat and enjoy it, vegetarianism is a better diet option because you won’t be contributing to animal cruelty, you can have more protection against certain diseases, and it will be easier for you to consume the vitamins that your body needs.

Thesis Sentences

Thesis sentence definition.

In order to provide insight, analysis, and/or interpretation, an essay needs a focus. An essay’s focus occurs in a thesis sentence, a sentence that provides the author’s main idea or argument in succinct form.

Most college essays will require a thesis sentence, a sentence in which you make a claim or proposition that you then support with evidence and examples, in order to prove the validity of that claim.  The thesis, which often comes toward the start of an essay, is the key idea of the whole essay, encapsulated in one sentence.

When you’re asked to write an “essay” as a course assignment, most likely you will be asked to write a thesis-support essay.

Thesis-support essays are just what their name implies. They offer a thesis near the start of the essay, usually at the end of the introductory paragraph, and then follow with supporting ideas and information. Usually, each unit of support starts with a topic sentence which extracts an idea from the thesis and makes a point about that part of the thesis idea.

Here’s a way to visualize a basic thesis-support essay:

Writing a good thesis sentence is key to academic essay writing, as it captures the essence of the writer’s insight. The rest of the essay can then develop from, elaborate on, and offer evidence for the thesis sentence’s idea. In other words, the thesis sentence makes a promise, or sets up an expectation, for the type of information to follow in the essay.

Definition Thesis Statement

A thesis statement captures the main idea of a paper in one or two sentences . Your thesis statement points the reader to your interpretation of the subject under discussion and is important to the research question .

For example, if the topic is Mark Twain’s novel Huckleberry Finn , the thesis statement offers a way to understand and interpret this novel by focusing on specific aspects. Moreover, a thesis statement tells the reader what your paper is about and how you will build up your argument.

What is a thesis statement and why is it important?

The thesis statement outlines the thesis topic in 1-2 sentences. The reader should know immediately after reading the thesis statement what the paper is about and the stance that the author holds regarding this topic. The thesis statement leads to the body paragraphs and it sets up the reader for the rest of the paper.

Are there thesis statement examples?

Yes! You can find many thesis statement examples online. These examples will show you how a thesis statement is typically structured and the link that it holds with the thesis topic and research question. Thesis statement examples should inspire you only- it’s important to come up with your own thesis topic and thesis statement.

Where does the thesis statement go in a paper?

The thesis statement should be placed towards the end of the introduction for optimal thesis formatting . The beginning of the introduction supplies the reader with the background information they’ll need to understand your thesis statement. Whereas the sentences following the thesis statement lead into the body of your paper.

How do you write a strong thesis statement?

A strong thesis statement should be clear, consise and very specific. It will set the tone for the paper and your position regarding the topic needs to be clear to the reader. Always start with a research question before turning it into a declaration that is supported by evidence that you found during the research phase. Having some trouble with the wording of your thesis? Check out some useful transition words to get the inspiration flowing.

What are the steps in writing a thesis statement?

First, you need to have decided on your thesis topic. Then, you need to create a research question. The research question will be the basis of your thesis statement. To transform your research question into a thesis statement, you first turn the research question into a declaration that is supported by evidence you found whilst researching. Once you’ve done this, you have your working thesis statement!

Step-by-Step

Brainstorming and collecting information online or in scientific literature can serve as a good first step to writing a thesis statement. This will help you come up with a working thesis and ideas on how to structure a good argument. You cannot jump to formulating the thesis statement right after reading the essay assignment.

Thinking about specific aspects of the topic that you can use to build up your argument might take a while, but it is worth spending some time to come up with a well-written thesis statement.

How to write a thesis statement step by step:

Here are some examples of thesis statements (cf. JBirdwellBranson, https://www.servicescape.com/blog/25-thesis-statement-examples-that-will-make-writing-a-breeze, Last accessed 28 th  Mar 2019) to give you a better idea of how to formulate your own thesis statement.

Please note that the following sample thesis statements are intended as examples only, as they have not been fully researched. It is important that you come up with your own thesis statement based on your own research question. Only by giving your own thesis statement enough thought will you be able to argue convincingly.

Examples of good and bad thesis statements

A good thesis statement is specific , clear , original , and includes a comment on how you are positioning yourself with respect to the issue at hand. You must consistently avoid vague wording. Moreover, you should avoid stating the obvious, like “The point I want to make in my paper…”.

The following checklist will help you meet the afore-mentioned requirements for writing a good thesis statement.

Placement of the Thesis Statement

The thesis statement is an integral part of the first paragraph/the introduction of your essay, as it sets the scene of what is to come. After a brief introduction, the thesis statement reflects your point of view and summarizes the argument. Formulating the statement clearly and putting some thought into it ensures that your essay has a clear structure and focus – a common thread.

In course assignments, you are asked to convince the reader with your argument. This is just another form of persuasion (just as you might have to persuade your parents to let you use their car, or ask a friend to lend you money). Consequently, your thesis statement should give good reasons for readers to approve your line of argument.

Recommended: Harvard Referencing
