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.

Thesis Statements

What this handout is about.

This handout describes what a thesis statement is, how thesis statements work in your writing, and how you can craft or refine one for your draft.

Introduction

Writing in college often takes the form of persuasion—convincing others that you have an interesting, logical point of view on the subject you are studying. Persuasion is a skill you practice regularly in your daily life. You persuade your roommate to clean up, your parents to let you borrow the car, your friend to vote for your favorite candidate or policy. In college, course assignments often ask you to make a persuasive case in writing. You are asked to convince your reader of your point of view. This form of persuasion, often called academic argument, follows a predictable pattern in writing. After a brief introduction of your topic, you state your point of view on the topic directly and often in one sentence. This sentence is the thesis statement, and it serves as a summary of the argument you’ll make in the rest of your paper.

What is a thesis statement?

A thesis statement:

• tells the reader how you will interpret the significance of the subject matter under discussion.
• is a road map for the paper; in other words, it tells the reader what to expect from the rest of the paper.
• directly answers the question asked of you. A thesis is an interpretation of a question or subject, not the subject itself. The subject, or topic, of an essay might be World War II or Moby Dick; a thesis must then offer a way to understand the war or the novel.
• makes a claim that others might dispute.
• is usually a single sentence near the beginning of your paper (most often, at the end of the first paragraph) that presents your argument to the reader. The rest of the paper, the body of the essay, gathers and organizes evidence that will persuade the reader of the logic of your interpretation.

If your assignment asks you to take a position or develop a claim about a subject, you may need to convey that position or claim in a thesis statement near the beginning of your draft. The assignment may not explicitly state that you need a thesis statement because your instructor may assume you will include one. When in doubt, ask your instructor if the assignment requires a thesis statement. When an assignment asks you to analyze, to interpret, to compare and contrast, to demonstrate cause and effect, or to take a stand on an issue, it is likely that you are being asked to develop a thesis and to support it persuasively. (Check out our handout on understanding assignments for more information.)

How do I create a thesis?

A thesis is the result of a lengthy thinking process. Formulating a thesis is not the first thing you do after reading an essay assignment. Before you develop an argument on any topic, you have to collect and organize evidence, look for possible relationships between known facts (such as surprising contrasts or similarities), and think about the significance of these relationships. Once you do this thinking, you will probably have a “working thesis” that presents a basic or main idea and an argument that you think you can support with evidence. Both the argument and your thesis are likely to need adjustment along the way.

Writers use all kinds of techniques to stimulate their thinking and to help them clarify relationships or comprehend the broader significance of a topic and arrive at a thesis statement. For more ideas on how to get started, see our handout on brainstorming .

How do I know if my thesis is strong?

If there’s time, run it by your instructor or make an appointment at the Writing Center to get some feedback. Even if you do not have time to get advice elsewhere, you can do some thesis evaluation of your own. When reviewing your first draft and its working thesis, ask yourself the following :

• Do I answer the question? Re-reading the question prompt after constructing a working thesis can help you fix an argument that misses the focus of the question. If the prompt isn’t phrased as a question, try to rephrase it. For example, “Discuss the effect of X on Y” can be rephrased as “What is the effect of X on Y?”
• Have I taken a position that others might challenge or oppose? If your thesis simply states facts that no one would, or even could, disagree with, it’s possible that you are simply providing a summary, rather than making an argument.
• Is my thesis statement specific enough? Thesis statements that are too vague often do not have a strong argument. If your thesis contains words like “good” or “successful,” see if you could be more specific: why is something “good”; what specifically makes something “successful”?
• Does my thesis pass the “So what?” test? If a reader’s first response is likely to  be “So what?” then you need to clarify, to forge a relationship, or to connect to a larger issue.
• Does my essay support my thesis specifically and without wandering? If your thesis and the body of your essay do not seem to go together, one of them has to change. It’s okay to change your working thesis to reflect things you have figured out in the course of writing your paper. Remember, always reassess and revise your writing as necessary.
• Does my thesis pass the “how and why?” test? If a reader’s first response is “how?” or “why?” your thesis may be too open-ended and lack guidance for the reader. See what you can add to give the reader a better take on your position right from the beginning.

Suppose you are taking a course on contemporary communication, and the instructor hands out the following essay assignment: “Discuss the impact of social media on public awareness.” Looking back at your notes, you might start with this working thesis:

Social media impacts public awareness in both positive and negative ways.

You can use the questions above to help you revise this general statement into a stronger thesis.

• Do I answer the question? You can analyze this if you rephrase “discuss the impact” as “what is the impact?” This way, you can see that you’ve answered the question only very generally with the vague “positive and negative ways.”
• Have I taken a position that others might challenge or oppose? Not likely. Only people who maintain that social media has a solely positive or solely negative impact could disagree.
• Is my thesis statement specific enough? No. What are the positive effects? What are the negative effects?
• Does my thesis pass the “how and why?” test? No. Why are they positive? How are they positive? What are their causes? Why are they negative? How are they negative? What are their causes?
• Does my thesis pass the “So what?” test? No. Why should anyone care about the positive and/or negative impact of social media?

After thinking about your answers to these questions, you decide to focus on the one impact you feel strongly about and have strong evidence for:

Because not every voice on social media is reliable, people have become much more critical consumers of information, and thus, more informed voters.

This version is a much stronger thesis! It answers the question, takes a specific position that others can challenge, and it gives a sense of why it matters.

Let’s try another. Suppose your literature professor hands out the following assignment in a class on the American novel: Write an analysis of some aspect of Mark Twain’s novel Huckleberry Finn. “This will be easy,” you think. “I loved Huckleberry Finn!” You grab a pad of paper and write:

Mark Twain’s Huckleberry Finn is a great American novel.

You begin to analyze your thesis:

• Do I answer the question? No. The prompt asks you to analyze some aspect of the novel. Your working thesis is a statement of general appreciation for the entire novel.

Think about aspects of the novel that are important to its structure or meaning—for example, the role of storytelling, the contrasting scenes between the shore and the river, or the relationships between adults and children. Now you write:

In Huckleberry Finn, Mark Twain develops a contrast between life on the river and life on the shore.

• Do I answer the question? Yes!
• Have I taken a position that others might challenge or oppose? Not really. This contrast is well-known and accepted.
• Is my thesis statement specific enough? It’s getting there–you have highlighted an important aspect of the novel for investigation. However, it’s still not clear what your analysis will reveal.
• Does my thesis pass the “how and why?” test? Not yet. Compare scenes from the book and see what you discover. Free write, make lists, jot down Huck’s actions and reactions and anything else that seems interesting.
• Does my thesis pass the “So what?” test? What’s the point of this contrast? What does it signify?”

After examining the evidence and considering your own insights, you write:

Through its contrasting river and shore scenes, Twain’s Huckleberry Finn suggests that to find the true expression of American democratic ideals, one must leave “civilized” society and go back to nature.

This final thesis statement presents an interpretation of a literary work based on an analysis of its content. Of course, for the essay itself to be successful, you must now present evidence from the novel that will convince the reader of your interpretation.

• Literary Terms
• Definition & Examples
• When & How to Write a Thesis

I. What is a Thesis?

The thesis (pronounced thee -seez), also known as a thesis statement, is the sentence that introduces the main argument or point of view of a composition (formal essay, nonfiction piece, or narrative). It is the main claim that the author is making about that topic and serves to summarize and introduce that writing that will be discussed throughout the entire piece. For this reason, the thesis is typically found within the first introduction paragraph.

II. Examples of Theses

Here are a few examples of theses which may be found in the introductions of a variety of essays :

In “The Mending Wall,” Robert Frost uses imagery, metaphor, and dialogue to argue against the use of fences between neighbors.

In this example, the thesis introduces the main subject (Frost’s poem “The Mending Wall”), aspects of the subject which will be examined (imagery, metaphor, and dialogue) and the writer’s argument (fences should not be used).

While Facebook connects some, overall, the social networking site is negative in that it isolates users, causes jealousy, and becomes an addiction.

This thesis introduces an argumentative essay which argues against the use of Facebook due to three of its negative effects.

During the college application process, I discovered my willingness to work hard to achieve my dreams and just what those dreams were.

In this more personal example, the thesis statement introduces a narrative essay which will focus on personal development in realizing one’s goals and how to achieve them.

III. The Importance of Using a Thesis

Theses are absolutely necessary components in essays because they introduce what an essay will be about. Without a thesis, the essay lacks clear organization and direction. Theses allow writers to organize their ideas by clearly stating them, and they allow readers to be aware from the beginning of a composition’s subject, argument, and course. Thesis statements must precisely express an argument within the introductory paragraph of the piece in order to guide the reader from the very beginning.

IV. Examples of Theses in Literature

For examples of theses in literature, consider these thesis statements from essays about topics in literature:

In William Shakespeare’s “ Sonnet 46,” both physicality and emotion together form powerful romantic love.

This thesis statement clearly states the work and its author as well as the main argument: physicality and emotion create romantic love.

In The Scarlet Letter, Nathaniel Hawthorne symbolically shows Hester Prynne’s developing identity through the use of the letter A: she moves from adulteress to able community member to angel.

In this example, the work and author are introduced as well as the main argument and supporting points: Prynne’s identity is shown through the letter A in three ways: adulteress, able community member, and angel.

John Keats’ poem “To Autumn” utilizes rhythm, rhyme, and imagery to examine autumn’s simultaneous birth and decay.

This thesis statement introduces the poem and its author along with an argument about the nature of autumn. This argument will be supported by an examination of rhythm, rhyme, and imagery.

V. Examples of Theses in Pop Culture

Sometimes, pop culture attempts to make arguments similar to those of research papers and essays. Here are a few examples of theses in pop culture:

America’s food industry is making a killing and it’s making us sick, but you have the power to turn the tables.

The documentary Food Inc. examines this thesis with evidence throughout the film including video evidence, interviews with experts, and scientific research.

Orca whales should not be kept in captivity, as it is psychologically traumatizing and has caused them to kill their own trainers.

Blackfish uses footage, interviews, and history to argue for the thesis that orca whales should not be held in captivity.

VI. Related Terms

Just as a thesis is introduced in the beginning of a composition, the hypothesis is considered a starting point as well. Whereas a thesis introduces the main point of an essay, the hypothesis introduces a proposed explanation which is being investigated through scientific or mathematical research. Thesis statements present arguments based on evidence which is presented throughout the paper, whereas hypotheses are being tested by scientists and mathematicians who may disprove or prove them through experimentation. Here is an example of a hypothesis versus a thesis:

Hypothesis:

Students skip school more often as summer vacation approaches.

This hypothesis could be tested by examining attendance records and interviewing students. It may or may not be true.

Students skip school due to sickness, boredom with classes, and the urge to rebel.

This thesis presents an argument which will be examined and supported in the paper with detailed evidence and research.

Introduction

A paper’s introduction is its first paragraph which is used to introduce the paper’s main aim and points used to support that aim throughout the paper. The thesis statement is the most important part of the introduction which states all of this information in one concise statement. Typically, introduction paragraphs require a thesis statement which ties together the entire introduction and introduces the rest of the paper.

VII. Conclusion

Theses are necessary components of well-organized and convincing essays, nonfiction pieces, narratives , and documentaries. They allow writers to organize and support arguments to be developed throughout a composition, and they allow readers to understand from the beginning what the aim of the composition is.

What is a thesis statement? [with example]

What is a thesis statement?

Purpose of a thesis statement, how to write the best thesis statement, thesis statement example, frequently asked questions about thesis statements, related articles.

A thesis statement is a concise description of the goal of your work. This element is one of the most essential components of academic writing , as it tells your readers what they can expect in your paper.

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

If you find yourself in the process of writing a a paper, but you don't know how to create a thesis statement , you've come to the right place. In the next paragraphs, you will learn about the most important elements of a thesis statement and how to come up with one.

A thesis statement highlights the main topic, shows how it will evolve, and conveys clearly the aim of your work. It does not only share the topic but it conveys the conclusion you came up with.

A good thesis statement provides directions for the development of the topic throughout the paper. In sum, this element of academic writing is crucial to sound research .

You can create a great thesis statement by following the format we outlined in our guide How to write a thesis statement .

In general, you should adhere to the following tips to write the best thesis statement:

• Focus the main idea of your thesis into one or two sentences.
• Write the answer to the main question of your topic.
• Clearly state your position in relation to the topic.
• Do not state the obvious. Give a disputable stance that requires evidence.

Tip: To check if your thesis is clear, explain it to a peer or colleague. If they are confused, then you likely need to re-write it.

Here's an example of a thesis statement:

In what follows, I will explore Fiorina’s position in more depth, focusing especially on her claim that technology is "a great tool for democratization." Ultimately, I argue that the primary problem with Fiorina’s stance lies in her laissez-faire understanding of technology. By granting technology a kind of independent existence apart from human motivation and intent—by positing that "technology permits anybody to play," as if it possesses an autonomy all its own—Fiorina unwittingly opens the way for the very kind of discriminatory and undemocratic mechanisms that her position seemingly rejects.

Tip: Once you finish your paper, return to your thesis statement to make sure that it reflects what you actually wrote.

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. It really depends on your academic and expertise level. 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.

Yes. Every good essay should include a thesis statement as part of its introduction. Of course, if you are a high school student you are not expected to have an extremely elaborate statement. A couple of clear sentences indicating the aim of your essay will be more than enough.

What is a thesis statement?

A thesis statement is an essential component of ALL academic and research writing.

A thesis statement:

• occurs early in a piece of written work (introduction)
• tells the reader what the purpose and scope of the work will be
• provides more than a mere description of the topic
• puts a ‘wager’ (i.e. a bet) on the topic by telling us what the significance of the research will be
• defines what will be investigated and what they think will be found (note, it’s OK if the hypothesis is disproven once the data is in)

Descriptive thesis statements

Beware thesis statements that are too descriptive because they “do not investigate anything, critique anything, or analyze anything […] they also do not invite support and argument from outside of the central text” ( UW Expository Writing Program, 2007, p. 2). The problem with thesis statements that are merely descriptive is that they lack a ‘stance’ or an argument. They are therefore difficult to support with evidence and to build an argument for.

The examples below would not make good thesis statements because they are too descriptive.

a) Shakespeare was a famous playwright during the Elizabethan era. He wrote numerous plays and poems.

b) Almost one in two marriages in Australia end in divorce. That means the divorce rate is almost 50%.

c) Covid-19 was a virus that caused an epidemic in the early 2020’s.

Check your understanding

Where is the thesis statement in the passage below?

My intention was to investigate and portray Antarctica through my own and others’ personal experiences, through historical examples of jewellery and souvenirs and through experimentation in the studio-based manufacture of new jewellery and souvenirs [e] . The objects produced through this research would reference the valued jewellery and souvenirs now displayed in museums as historical artefacts which were once personal mementos [f] . I was particularly interested in the potential of these objects to represent personal narratives and experiences of the past [g] . In this research project I have explored some of the ways in which I can make objects, specifically jewellery and souvenirs that draw on this rich heritage to present Antarctica in an innovative way [h] .

Thesis statement.

Definition:

The thesis is usually considered the most important sentence of your essay because it outlines the central purpose of your essay in one place. A good thesis will link the subject of an essay with a controlling idea. Consider, for example, the following thesis:

People in the past spent a great deal of effort protecting themselves from witches. Subject: people feared witches Controlling Idea: people spent a great deal of effort protecting themselves

In a short essay, a thesis statement appears at, or near, the end of the introductory paragraph of the paper so that readers know the topic of the essay before they see the writer's statement of the central purpose of the essay. This way the first paragraph helps the reader understand why the writer is writing.

A thesis should be narrow in focus in order to allow the fullest exploration of its issues as possible, and it should reflect the type of paper that follows, whether it be persuasive or informative. Narrowing the focus of the thesis may require posing questions about it to yourself before committing to a final version.

What follows is a method for writing thesis statements that many writers have found useful (we found it in Chapter 3 of The Allyn & Bacon Handbook ).

1. Decide what you are writing about:

A clear, concise thesis statement does more than outline the subject in question; it makes the reader aware of the writer's stand on the subject in question, connecting a subject with a controlling idea.

2. Think about all the elements your paper will deal with:

A thesis generally consists of a subject that contains within itself a number of smaller facts; the topic sentence of each paragraph that makes up the body of the paper should refer (in some clear way) back to the ideas contained within the thesis statement in order to keep the paper from digressing.

3. Think about the purpose and tone of your paper:

A thesis statement should contain the main point of the paper and suggest to the reader a direction that the paper will take in exploring, proving, or disproving that main point.

4. State your main point in a sentence or two:

A good writer can assert the main idea of a short, coherent essay briefly. Instead of rambling, be as straightforward as possible.

5. Revise your thesis as you develop your paper:

A final version of a thesis statement will only be available after a draft of the paper it is a part of has been completed. The focus of the paper may change and evolve over the period it is written in; necessarily, the thesis statement should be revised to reflect the alterations in the paper.

Few writers finish a paper writing about the exact topic they begin with. While you write a paper, your main point may change. As you're finishing, make sure your thesis statement has changed along with the subject and controlling ideas of your paper.

Thesis Statement and Controlling Idea

So what? This is the question you will get asked if your thesis statement, or main idea, is not obvious in your paper. Your thesis statement is the most important part of your writing; without it, your paper doesn’t have a main point or stance. A thesis statement states the purpose and topic of your writing, and the controlling idea indicates the direction and, often, the writing strategy you will adopt. 

Generally, your thesis is placed at the end of your introduction and is a concise and simple sentence that combines your topic and your position on the topic. Like a road map, your thesis lets your readers know what to expect from the rest of your paper. Your body paragraphs support it, and your essay lacks direction without it.

It is important to keep in mind that this early in your writing, your thesis statement is really a working thesis that you use to begin thinking about your topic. You may revise this thesis many times before you are finished thinking and ready to write your final draft. Below are some sample thesis statements.  

YOUR TOPIC + POSITION ON TOPIC = THESIS STATEMENT

Thesis Statement Do's and Don'ts

Present an argument, stance, or claim. Can your audience argue with it? 

Provide a key to the organization of your paper. Can you construct body paragraphs that support it? 

Mirror the assignment prompt. Are you following what is expected of you?

Present the thesis at the end of the introduction.  

Answer the question: “so what?”  

Present an argument that can be supported by reputable research. Is your argument logical?

Embrace the “how” and “why” elements. It’s a great strategy to present the problem, examine why it’s a problem, and show how it can be fixed. 

Include announcement style language like “this paper will discuss” or “this will be shown in this essay.” 

Be informative only with no argument or stance, such as, “Some high school seniors decide to take a gap year.” 

Include overly broad or generalized statements like, “Kids of this generation are lazy.”

Force the reader to guess what the paper will prove or discuss 

Be questions. 

Key Takeaways

Your thesis is one statement at the end of your introduction and should be clear, concise, and arguable.

Without a thesis, your paper lacks direction and purpose.

What Is a Thesis? | Ultimate Guide & Examples

Published on 15 September 2022 by Tegan George . Revised on 25 July 2024.

A thesis is a type of research paper based on your original research. It is usually submitted as the final step of a PhD program in the UK.

Writing a thesis can be a daunting experience. Indeed, alongside a dissertation , it is the longest piece of writing students typically complete. It relies on your ability to conduct research from start to finish: designing your research , collecting data , developing a robust analysis, drawing strong conclusions , and writing concisely .

You may have heard the word thesis as a standalone term or as a component of academic writing called a thesis statement . Keep in mind that these are two very different things.

• A thesis statement is a very common component of an essay, particularly in the humanities. It usually comprises 1 or 2 sentences in the introduction of your essay , and should clearly and concisely summarise the central points of your academic essay .
• A thesis is a long-form piece of academic writing, often taking more than a full semester to complete. It is generally a degree requirement to complete a PhD program.
• In many countries, particularly the UK, a dissertation is generally written at the bachelor’s or master’s level.
• In the US, a dissertation is generally written as a final step toward obtaining a PhD.

Prevent plagiarism, run a free check.

The final structure of your thesis depends on a variety of components, such as:

• Your discipline
• Your theoretical approach

Humanities theses are often structured more like a longer-form essay . Just like in an essay, you build an argument to support a central thesis.

In both hard and social sciences, theses typically include an introduction , literature review , methodology section ,  results section , discussion section , and conclusion section . These are each presented in their own dedicated section or chapter. In some cases, you might want to add an appendix .

Thesis examples

We’ve compiled a short list of thesis examples to help you get started.

• Example thesis #1:   ‘Abolition, Africans, and Abstraction: the Influence of the “Noble Savage” on British and French Antislavery Thought, 1787-1807’ by Suchait Kahlon.
• Example thesis #2: ‘”A Starving Man Helping Another Starving Man”: UNRRA, India, and the Genesis of Global Relief, 1943-1947’ by Julian Saint Reiman.

The very first page of your thesis contains all necessary identifying information, including:

• Your full title
• Your full name
• Your department
• Your institution and degree program
• Your submission date.

Sometimes the title page also includes your student ID, the name of your supervisor, or the university’s logo. Check out your university’s guidelines if you’re not sure.

Read more about title pages

The acknowledgements section is usually optional. Its main point is to allow you to thank everyone who helped you in your thesis journey, such as supervisors, friends, or family. You can also choose to write a preface , but it’s typically one or the other, not both.

The only proofreading tool specialized in correcting academic writing

The academic proofreading tool has been trained on 1000s of academic texts and by native English editors. Making it the most accurate and reliable proofreading tool for students.

Correct my document today

An abstract is a short summary of your thesis. Usually a maximum of 300 words long, it’s should include brief descriptions of your research objectives , methods, results, and conclusions. Though it may seem short, it introduces your work to your audience, serving as a first impression of your thesis.

Read more about abstracts

A table of contents lists all of your sections, plus their corresponding page numbers and subheadings if you have them. This helps your reader seamlessly navigate your document.

Your table of contents should include all the major parts of your thesis. In particular, don’t forget the the appendices. If you used heading styles, it’s easy to generate an automatic table Microsoft Word.

Read more about tables of contents

While not mandatory, if you used a lot of tables and/or figures, it’s nice to include a list of them to help guide your reader. It’s also easy to generate one of these in Word: just use the ‘Insert Caption’ feature.

Read more about lists of figures and tables

If you have used a lot of industry- or field-specific abbreviations in your thesis, you should include them in an alphabetised list of abbreviations . This way, your readers can easily look up any meanings they aren’t familiar with.

Read more about lists of abbreviations

Relatedly, if you find yourself using a lot of very specialised or field-specific terms that may not be familiar to your reader, consider including a glossary . Alphabetise the terms you want to include with a brief definition.

Read more about glossaries

An introduction sets up the topic, purpose, and relevance of your thesis, as well as expectations for your reader. This should:

• Ground your research topic , sharing any background information your reader may need
• Define the scope of your work
• Introduce any existing research on your topic, situating your work within a broader problem or debate
• State your research question(s)
• Outline (briefly) how the remainder of your work will proceed

In other words, your introduction should clearly and concisely show your reader the “what, why, and how” of your research.

Read more about introductions

A literature review helps you gain a robust understanding of any extant academic work on your topic, encompassing:

• Selecting relevant sources
• Determining the credibility of your sources
• Critically evaluating each of your sources
• Drawing connections between sources, including any themes, patterns, conflicts, or gaps

A literature review is not merely a summary of existing work. Rather, your literature review should ultimately lead to a clear justification for your own research, perhaps via:

• Addressing a gap in the literature
• Building on existing knowledge to draw new conclusions
• Exploring a new theoretical or methodological approach
• Introducing a new solution to an unresolved problem
• Definitively advocating for one side of a theoretical debate

Read more about literature reviews

Theoretical framework

Your literature review can often form the basis for your theoretical framework, but these are not the same thing. A theoretical framework defines and analyses the concepts and theories that your research hinges on.

Read more about theoretical frameworks

Your methodology chapter shows your reader how you conducted your research. It should be written clearly and methodically, easily allowing your reader to critically assess the credibility of your argument. Furthermore, your methods section should convince your reader that your method was the best way to answer your research question.

A methodology section should generally include:

• Your overall approach ( quantitative vs. qualitative )
• Your research methods (e.g., a longitudinal study )
• Your data collection methods (e.g., interviews or a controlled experiment
• Any tools or materials you used (e.g., computer software)
• The data analysis methods you chose (e.g., statistical analysis , discourse analysis )
• A strong, but not defensive justification of your methods

Read more about methodology sections

Your results section should highlight what your methodology discovered. These two sections work in tandem, but shouldn’t repeat each other. While your results section can include hypotheses or themes, don’t include any speculation or new arguments here.

Your results section should:

• State each (relevant) result with any (relevant) descriptive statistics (e.g., mean , standard deviation ) and inferential statistics (e.g., test statistics , p values )
• Explain how each result relates to the research question
• Determine whether the hypothesis was supported

Additional data (like raw numbers or interview transcripts ) can be included as an appendix . You can include tables and figures, but only if they help the reader better understand your results.

Read more about results sections

Your discussion section is where you can interpret your results in detail. Did they meet your expectations? How well do they fit within the framework that you built? You can refer back to any relevant source material to situate your results within your field, but leave most of that analysis in your literature review.

For any unexpected results, offer explanations or alternative interpretations of your data.

Read more about discussion sections

Your thesis conclusion should concisely answer your main research question. It should leave your reader with an ultra-clear understanding of your central argument, and emphasise what your research specifically has contributed to your field.

Why does your research matter? What recommendations for future research do you have? Lastly, wrap up your work with any concluding remarks.

Read more about conclusions

In order to avoid plagiarism , don’t forget to include a full reference list at the end of your thesis, citing the sources that you used. Choose one citation style and follow it consistently throughout your thesis, taking note of the formatting requirements of each style.

Which style you choose is often set by your department or your field, but common styles include MLA , Chicago , and APA.

Create APA citations Create MLA citations

In order to stay clear and concise, your thesis should include the most essential information needed to answer your research question. However, chances are you have many contributing documents, like interview transcripts or survey questions . These can be added as appendices , to save space in the main body.

Read more about appendices

Once you’re done writing, the next part of your editing process begins. Leave plenty of time for proofreading and editing prior to submission. Nothing looks worse than grammar mistakes or sloppy spelling errors!

Consider using a professional thesis editing service to make sure your final project is perfect.

Once you’ve submitted your final product, it’s common practice to have a thesis defense, an oral component of your finished work. This is scheduled by your advisor or committee, and usually entails a presentation and Q&A session.

After your defense, your committee will meet to determine if you deserve any departmental honors or accolades. However, keep in mind that defenses are usually just a formality. If there are any serious issues with your work, these should be resolved with your advisor way before a defense.

The conclusion of your thesis or dissertation shouldn’t take up more than 5-7% of your overall word count.

When you mention different chapters within your text, it’s considered best to use Roman numerals for most citation styles. However, the most important thing here is to remain consistent whenever using numbers in your dissertation .

If you only used a few abbreviations in your thesis or dissertation, you don’t necessarily need to include a list of abbreviations .

If your abbreviations are numerous, or if you think they won’t be known to your audience, it’s never a bad idea to add one. They can also improve readability, minimising confusion about abbreviations unfamiliar to your reader.

A thesis or dissertation outline is one of the most critical first steps in your writing process. It helps you to lay out and organise your ideas and can provide you with a roadmap for deciding what kind of research you’d like to undertake.

Generally, an outline contains information on the different sections included in your thesis or dissertation, such as:

• Your anticipated title
• Your abstract
• Your chapters (sometimes subdivided into further topics like literature review, research methods, avenues for future research, etc.)

Frequently asked questions

What is a thesis statement.

A thesis statement is a sentence that sums up the central point of your paper or essay . Everything else you write should relate to this key idea.

Frequently asked questions: Writing an essay

For a stronger conclusion paragraph, avoid including:

• Important evidence or analysis that wasn’t mentioned in the main body
• Generic concluding phrases (e.g. “In conclusion…”)
• Weak statements that undermine your argument (e.g. “There are good points on both sides of this issue.”)

Your conclusion should leave the reader with a strong, decisive impression of your work.

Your essay’s conclusion should contain:

• A rephrased version of your overall thesis
• A brief review of the key points you made in the main body
• An indication of why your argument matters

The conclusion may also reflect on the broader implications of your argument, showing how your ideas could applied to other contexts or debates.

The conclusion paragraph of an essay is usually shorter than the introduction . As a rule, it shouldn’t take up more than 10–15% of the text.

An essay is a focused piece of writing that explains, argues, describes, or narrates.

In high school, you may have to write many different types of essays to develop your writing skills.

Academic essays at college level are usually argumentative : you develop a clear thesis about your topic and make a case for your position using evidence, analysis and interpretation.

The “hook” is the first sentence of your essay introduction . It should lead the reader into your essay, giving a sense of why it’s interesting.

To write a good hook, avoid overly broad statements or long, dense sentences. Try to start with something clear, concise and catchy that will spark your reader’s curiosity.

Your essay introduction should include three main things, in this order:

• An opening hook to catch the reader’s attention.
• Relevant background information that the reader needs to know.
• A thesis statement that presents your main point or argument.

The length of each part depends on the length and complexity of your essay .

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.

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.

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.

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.

The thesis statement is essential in any academic essay or research paper for two main reasons:

• It gives your writing direction and focus.
• It gives the reader a concise summary of your main point.

Without a clear thesis statement, an essay can end up rambling and unfocused, leaving your reader unsure of exactly what you want to say.

The thesis statement should be placed at the end of your essay introduction .

Follow these four steps to come up with a thesis statement :

• Ask a question about your topic .
• Write your initial answer.
• Develop your answer by including reasons.
• Refine your answer, adding more detail and nuance.

An essay isn’t just a loose collection of facts and ideas. Instead, it should be centered on an overarching argument (summarized in your thesis statement ) that every part of the essay relates to.

The way you structure your essay is crucial to presenting your argument coherently. A well-structured essay helps your reader follow the logic of your ideas and understand your overall point.

The structure of an essay is divided into an introduction that presents your topic and thesis statement , a body containing your in-depth analysis and arguments, and a conclusion wrapping up your ideas.

The structure of the body is flexible, but you should always spend some time thinking about how you can organize your essay to best serve your ideas.

The vast majority of essays written at university are some sort of argumentative essay . Almost all academic writing involves building up an argument, though other types of essay might be assigned in composition classes.

Essays can present arguments about all kinds of different topics. For example:

• In a literary analysis essay, you might make an argument for a specific interpretation of a text
• In a history essay, you might present an argument for the importance of a particular event
• In a politics essay, you might argue for the validity of a certain political theory

At high school and in composition classes at university, you’ll often be told to write a specific type of essay , but you might also just be given prompts.

Look for keywords in these prompts that suggest a certain approach: The word “explain” suggests you should write an expository essay , while the word “describe” implies a descriptive essay . An argumentative essay might be prompted with the word “assess” or “argue.”

In rhetorical analysis , a claim is something the author wants the audience to believe. A support is the evidence or appeal they use to convince the reader to believe the claim. A warrant is the (often implicit) assumption that links the support with the claim.

Logos appeals to the audience’s reason, building up logical arguments . Ethos appeals to the speaker’s status or authority, making the audience more likely to trust them. Pathos appeals to the emotions, trying to make the audience feel angry or sympathetic, for example.

Collectively, these three appeals are sometimes called the rhetorical triangle . They are central to rhetorical analysis , though a piece of rhetoric might not necessarily use all of them.

The term “text” in a rhetorical analysis essay refers to whatever object you’re analyzing. It’s frequently a piece of writing or a speech, but it doesn’t have to be. For example, you could also treat an advertisement or political cartoon as a text.

The goal of a rhetorical analysis is to explain the effect a piece of writing or oratory has on its audience, how successful it is, and the devices and appeals it uses to achieve its goals.

Unlike a standard argumentative essay , it’s less about taking a position on the arguments presented, and more about exploring how they are constructed.

You should try to follow your outline as you write your essay . However, if your ideas change or it becomes clear that your structure could be better, it’s okay to depart from your essay outline . Just make sure you know why you’re doing so.

If you have to hand in your essay outline , you may be given specific guidelines stating whether you have to use full sentences. If you’re not sure, ask your supervisor.

When writing an essay outline for yourself, the choice is yours. Some students find it helpful to write out their ideas in full sentences, while others prefer to summarize them in short phrases.

You will sometimes be asked to hand in an essay outline before you start writing your essay . Your supervisor wants to see that you have a clear idea of your structure so that writing will go smoothly.

Even when you do not have to hand it in, writing an essay outline is an important part of the writing process . It’s a good idea to write one (as informally as you like) to clarify your structure for yourself whenever you are working on an essay.

Comparisons in essays are generally structured in one of two ways:

• The alternating method, where you compare your subjects side by side according to one specific aspect at a time.
• The block method, where you cover each subject separately in its entirety.

It’s also possible to combine both methods, for example by writing a full paragraph on each of your topics and then a final paragraph contrasting the two according to a specific metric.

Your subjects might be very different or quite similar, but it’s important that there be meaningful grounds for comparison . You can probably describe many differences between a cat and a bicycle, but there isn’t really any connection between them to justify the comparison.

You’ll have to write a thesis statement explaining the central point you want to make in your essay , so be sure to know in advance what connects your subjects and makes them worth comparing.

Some essay prompts include the keywords “compare” and/or “contrast.” In these cases, an essay structured around comparing and contrasting is the appropriate response.

Comparing and contrasting is also a useful approach in all kinds of academic writing : You might compare different studies in a literature review , weigh up different arguments in an argumentative essay , or consider different theoretical approaches in a theoretical framework .

The key difference is that a narrative essay is designed to tell a complete story, while a descriptive essay is meant to convey an intense description of a particular place, object, or concept.

Narrative and descriptive essays both allow you to write more personally and creatively than other kinds of essays , and similar writing skills can apply to both.

If you’re not given a specific prompt for your descriptive essay , think about places and objects you know well, that you can think of interesting ways to describe, or that have strong personal significance for you.

The best kind of object for a descriptive essay is one specific enough that you can describe its particular features in detail—don’t choose something too vague or general.

If you’re not given much guidance on what your narrative essay should be about, consider the context and scope of the assignment. What kind of story is relevant, interesting, and possible to tell within the word count?

The best kind of story for a narrative essay is one you can use to reflect on a particular theme or lesson, or that takes a surprising turn somewhere along the way.

Don’t worry too much if your topic seems unoriginal. The point of a narrative essay is how you tell the story and the point you make with it, not the subject of the story itself.

Narrative essays are usually assigned as writing exercises at high school or in university composition classes. They may also form part of a university application.

When you are prompted to tell a story about your own life or experiences, a narrative essay is usually the right response.

The majority of the essays written at university are some sort of argumentative essay . Unless otherwise specified, you can assume that the goal of any essay you’re asked to write is argumentative: To convince the reader of your position using evidence and reasoning.

In composition classes you might be given assignments that specifically test your ability to write an argumentative essay. Look out for prompts including instructions like “argue,” “assess,” or “discuss” to see if this is the goal.

At college level, you must properly cite your sources in all essays , research papers , and other academic texts (except exams and in-class exercises).

Add a citation whenever you quote , paraphrase , or summarize information or ideas from a source. You should also give full source details in a bibliography or reference list at the end of your text.

The exact format of your citations depends on which citation style you are instructed to use. The most common styles are APA , MLA , and Chicago .

An argumentative essay tends to be a longer essay involving independent research, and aims to make an original argument about a topic. Its thesis statement makes a contentious claim that must be supported in an objective, evidence-based way.

An expository essay also aims to be objective, but it doesn’t have to make an original argument. Rather, it aims to explain something (e.g., a process or idea) in a clear, concise way. Expository essays are often shorter assignments and rely less on research.

An expository essay is a common assignment in high-school and university composition classes. It might be assigned as coursework, in class, or as part of an exam.

Sometimes you might not be told explicitly to write an expository essay. Look out for prompts containing keywords like “explain” and “define.” An expository essay is usually the right response to these prompts.

An expository essay is a broad form that varies in length according to the scope of the assignment.

Expository essays are often assigned as a writing exercise or as part of an exam, in which case a five-paragraph essay of around 800 words may be appropriate.

You’ll usually be given guidelines regarding length; if you’re not sure, ask.

Definition of thesis

Did you know.

In high school, college, or graduate school, students often have to write a thesis on a topic in their major field of study. In many fields, a final thesis is the biggest challenge involved in getting a master's degree, and the same is true for students studying for a Ph.D. (a Ph.D. thesis is often called a dissertation ). But a thesis may also be an idea; so in the course of the paper the student may put forth several theses (notice the plural form) and attempt to prove them.

What is a Thesis? Definition, Examples of Theses in Literature

Home » The Writer’s Dictionary » What is a Thesis? Definition, Examples of Theses in Literature

Thesis definition: A thesis is a statement in which the writer conveys his position regarding a topic.

What is a Thesis?

A thesis statement refers to part of an essay where the writer establishes his position regarding a topic. This is the position that the writer will further explore throughout his paper.

Example of Thesis

• Topic : religious freedom.
• Thesis : All citizens of the United States should be allowed to exercise the religion of their choice freely without interference from government.
• Explanation : In this thesis statement, the writer has taken the position that all citizens should be free to worship and practice their religion as they see fit. The government should not pressure citizens into any religion, and it should not persecute members of any faith community.

The Importance of a Thesis Statement

Thesis statements are important in order to establish the writer’s position regarding a topic or idea. They help to introduce the essay and set a focus for the reader.

Narrative thesis statements are found in narrative essays or in literature. They set the scene for the lesson that will be explored or taught through the piece.

Famous opening lines that exemplify a narrative thesis:

• The following narrative thesis is found in A Tale of Two Cities by Charles Dickens:

“It was the best of times, it was the worst of times, it was the age of wisdom, it was the age of foolishness, it was the epoch of belief, it was the epoch of incredulity, it was the season of Light, it was the season of Darkness, it was the spring of hope, it was the winter of despair.”

The Function of Thesis in Literature

Narrative thesis statements are important in literature in order to establish the purpose for the work or introduce the lesson that the novel will attempt to teach. This allows the reader to have a focus when beginning the novel in order to effectively engage them into the story.

Examples of Theses in Literature

In the memoir, I am Malala by Malala Yousafzai, a thesis statement can be found in the beginning pages of her story.

• “One year ago I left my home for school and never returned. I was shot by a Taliban bullet and was flown out of Pakistan unconscious. Some people say I will never return home, but I believe firmly in my heart that I will. To be torn from the country that you love is not something to wish on anyone.”

In this thesis statement, Yousafzai establishes the basis of her memoir, which is to tell the story of how she was forced to leave her home.

In Vladmir Nabokov’s Lolita , a thesis can be seen in the line, “Lolita, light of my life, the fire of my loins”.

Here the narrator establishes the identity of the young nymph that he is unhealthily obsessed with in the story. Lolita is a young child while he is a grown man; therefore, this statement creates the uneasy feeling about him that continues throughout the novel.

Summary: What Are Theses?

Define thesis in literature: In summation, a thesis statement establishes a purpose in the piece of writing. It may establish the lesson or story to be told, or in an essay it may establish the position the writer assumes when exploring a topic.

Either way, it is important for the thesis to be clear in order to effectively convey the writer’s message.

Final Example:

In Edgar Allan Poe’s “The Cask of Amontillado,” the thesis statement can be found in the first line of the short story. Montresor immediately states his purpose, “the thousand injuries of Fortunato I had borne as best I could, but when he ventured upon insult I vowed revenge.”

In this statement, Montresor states that he will be seeking revenge after being treated wrongly by Fortunato. By beginning the story with the narrative thesis establishes the purpose for the remainder of the piece.

What is a thesis?

A thesis is

• an academic body of work
• a writer’s, speaker’s, or knowledge worker’s . . . main reason for communicating ; their purpose .

Related Concepts: Organizational Schema; Professional Writing Prose Style

Note: Some people consider thesis and purpose to be synonymous terms. Others view purpose to be a broader classification of discourse and thesis to be a more specific message or argument.

A writer’s thesis is the writer’s north star.

Writer’s, speaker’s, or knowledge worker’s . . . need to know their purpose , their reason for writing, in order to know how they need to compose their texts or submit those texts to their intended audiences .

A thesis may be expressed as

• an argumentative theses (Dietrich)
• an organizational theses
• a research question

While writers need to know what their purpose is for communicating in order to communicate clearly , concisely , and in a unified manner, they do not necessarily need to explicitly state their theses . In fact, there are some rhetorical circumstances when the tone and voice might be better served by leaving the context and purpose unsaid, implied, tacit.

Thesis Statements are commonplace in Workplace contexts. It is commonplace–especially in workplace writing–for writers, speakers, knowledge workers . . . to explicitly state their thesis in the first or second sentence of their texts. This sort of approach is sometimes called a Direct Style as opposed to an Indirect Style , or a Deductive Approach as opposed to an Inductive Approach .

Examples of genres of discourse that emploay a direct style include business correspondence, executive abstracts, abstracts, executive summaries, and introductions to workplace writing.

However, there are occasions when it’s rhetorically most strategic for a writer, speaker, knowledge worker . . . to view the context to be so routine that it goes without saying between the writer and the reader, the speaker and the audience.

What are the functions of a thesis?

The thesis functions in several important ways:

• It informs the reader of the paper’s direction

The thesis announces the direction of the paper’s conversation. Readers may find the paper’s position or argument more convincing if they know what to expect as they read.

• It places boundaries on the paper’s content

The body of the paper provides support for the thesis. Only evidence and details that relate directly to the paper’s main ideas should fall within the boundary established by the thesis.

• It determines how the content will be organized

The thesis summarizes the message or conclusion the reader is meant to understand and accept. A logical progression of these ideas and their supporting evidence helps shape the paper’s organization.
