topic sentence and thesis statement difference

Difference Between Topic Sentence Vs. Thesis Statement

After being introduced during the K-12 years of a student's education, academic writing is a mainstay in college and higher education. With proper format and technique being a major aspect of academic writing, it is essential for students to understand the differences between a topic sentence and a thesis statement.

1 Essay Format

Before delving into the differences between topic sentences and thesis statements, it is important to first establish the general format for a written essay. For K-12 students, written essays can commonly require the five-paragraph format, which consist of an introduction, three paragraphs that make up the body of the paper and the final paragraph as the conclusion. By understanding this general format of academic writing, it is easier to understand where topic sentences and thesis statements fit into place.

2 Topic Sentences

Topic sentences are used in each major paragraph of an essay paper. The purposes of these sentences are to develop and state the key idea of each paragraph in an effort to define the point of the paragraph. For example, when writing an essay paper on the effects of the Gettysburg Address, one of the paragraphs in the body of the paper could discuss how the audience received President Lincoln's famous speech. The topic sentence for this paragraph could be, "With the brief yet poignant nature of the Gettysburg Address, President Lincoln reminded his audience why the country was fighting so desperately to conserve the Union."

3 Thesis Statement

A thesis statement is a single sentence that is used to define the purpose of your paper. Thesis statements inform readers as to the purpose of your paper. After reading your thesis statement, anyone reviewing your paper should be able to determine what your paper is going to prove or argue. For example, a thesis statement for a paper about William Shakespeare's famous play "Romeo and Juliet" could be as follows: "The play 'Romeo and Juliet' demonstrates the incredible power and impatient nature of young love, as the star-crossed lovers' inability to exercise patience or control their passion for one another results in their deaths."

4 Differences

With the purposes of both topic sentences and thesis statements established, the differences between the two are clear. Thesis statements need to be more broad and leave room to expand on further points to support the paper's argument. With the thesis statement in the previous section, a writer could continue explaining his argument about Romeo and Juliet by providing sub-points, demonstrating instances where the pair made hasty choices that had fatal consequences. Topic sentences are more specific in their purpose. For example, with the topic sentence in section two, it is clear that the next paragraph will discuss how President Lincoln used the Gettysburg Address to remind his countrymen about the purpose of the Civil War.

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.

5.2: Identifying Thesis Statements and Topic Sentences

• Last updated

• Page ID 25748

Being able to identify the purpose and thesis of a text, as you’re reading it, takes practice. This section will offer you that practice.

One fun strategy for developing a deeper understanding the material you’re reading is to make a visual “map” of the ideas. Mind maps, whether hand-drawn or done through computer programs, can be fun to make, and help put all the ideas of an essay you’re reading in one easy-to-read format.

Your understanding of what the “central” element of the mind map is might change as you read and re-read. Developing the central idea of your mind map is a great way to help you determine the reading’s thesis.

Locating Explicit and Implicit Thesis Statements

In academic writing, the thesis is often explicit : it is included as a sentence as part of the text. It might be near the beginning of the work, but not always–some types of academic writing leave the thesis until the conclusion.

Journalism and reporting also rely on explicit thesis statements that appear very early in the piece–the first paragraph or even the first sentence.

Works of literature, on the other hand, usually do not contain a specific sentence that sums up the core concept of the writing. However, readers should finish the piece with a good understanding of what the work was trying to convey. This is what’s called an implicit thesis statement: the primary point of the reading is conveyed indirectly, in multiple locations throughout the work. (In literature, this is also referred to as the theme of the work.)

Academic writing sometimes relies on implicit thesis statements, as well.

This video offers excellent guidance in identifying the thesis statement of a work, no matter if it’s explicit or implicit.

Topic Sentences

We’ve learned that a thesis statement conveys the primary message of an entire piece of text. Now, let’s look at the next level of important sentences in a piece of text: topic sentences in each paragraph.

A useful metaphor would be to think of the thesis statement of a text as a general: it controls all the major decisions of the writing. There is only one thesis statement in a text. Topic sentences, in this relationship, serve as captains: they organize and sub-divide the overall goals of a writing into individual components. Each paragraph will have a topic sentence.

Figure 2.5. 2

It might be helpful to think of a topic sentence as working in two directions simultaneously. It relates the paragraph to the essay’s thesis, and thereby acts as a signpost for the argument of the paper as a whole, but it also defines the scope of the paragraph itself. For example, consider the following topic sentence:

Many characters in Lorraine Hansberry’s play A Raisin in the Sun have one particular dream in which they are following, though the character Walter pursues his most aggressively.

If this sentence controls the paragraph that follows, then all sentences in the paragraph must relate in some way to Walter and the pursuit of his dream.

Topic sentences often act like tiny thesis statements. Like a thesis statement, a topic sentence makes a claim of some sort. As the thesis statement is the unifying force in the essay, so the topic sentence must be the unifying force in the paragraph. Further, as is the case with the thesis statement, when the topic sentence makes a claim, the paragraph which follows must expand, describe, or prove it in some way. Topic sentences make a point and give reasons or examples to support it.

 The following diagram illustrates how a topic sentence can provide more focus to the general topic at hand.

Placement of Topic Sentences

What if I told you that the topic sentence doesn’t necessarily need to be at the beginning? This might be contrary to what you’ve learned in previous English or writing classes, and that’s okay. Certainly, when authors announce a topic clearly and early on in a paragraph, their readers are likely to grasp their idea and to make the connections that they want them to make.

However, when authors are writing for a more sophisticated academic audience—that is an audience of college-educated readers—they will often use more sophisticated organizational strategies to build and reveal ideas in their writing. One way to think about a topic sentence, is that it presents the broadest view of what authors want their readers to understand. This is to say that they’re providing a broad statement that either announces or brings into focus the purpose or the meaning for the details of the paragraph. If the topic sentence is seen as the broadest view, then every supporting detail will bring a narrower—or more specific—view of the same topic.

With this in mind, take some time to contemplate the diagrams in the figure below. The widest point of each diagram (the bases of the triangles) represents the topic sentence of the paragraph. As details are presented, the topic becomes narrower and more focused. The topic can precede the details, it can follow them, it can both precede and follow them, or the details can surround the topic. There are surely more alternatives than those that are presented here, but this gives you an idea of some of the possible paragraph structures and possible placements for the topic sentence of a paragraph.

Consider some of the following examples of different topic sentence placements in a paragraph from a review essay of the beloved children’s book, The Cat in the Hat , by Dr. Seuss. Paragraph structures are labeled according to the diagrams presented above, and topic sentences are identified by red text.

Topic Sentence-Details-Topic Sentence

A good children’s book requires an exciting plot and a problem with which children can sympathize. In The Cat in the Hat there is plenty of action, depicted in the wild antics of the cat, and later in the amazing but dangerous and messy tricks of Thing 1 and Thing 2. All this excitement and action naturally draws children into the story and keeps the plot moving forward at a pace that maintains their interest. There is also tension to be resolved. The fish senses danger and constantly warns the children not to participate in the cat’s perilous stunts. And later, as the mother’s return becomes more imminent, the children begin to heed the fish’s warning and finally wish to contain the chaos and clean up the mess, but how? While this plot is fantastic enough to fuel any child’s imagination, it also contains a problem with which any child can relate: a mess and the threat of a parent’s disapproval. The careful balance of action, tension, and relatability is what makes this book an enduring childhood favorite.

The careful balance of action, tension, and relatability is what makes Dr. Seuss’s The Cat in the Hat an enduring childhood favorite. In The Cat in the Hat there is plenty of action, depicted in the wild antics of the cat, and later in the amazing but dangerous and messy tricks of Thing 1 and Thing 2. All this excitement and action naturally draws children into the story and keeps the plot moving forward at a pace that maintains their interest. There is also tension to be resolved.

You can relocate the topic sentence to the end here, and you’ll have an example of the Details-Topic Sentence method of organizing the paragraph.

All this excitement and action naturally draws children into the story and keeps the plot moving forward at a pace that maintains their interest. The careful balance of action, tension, and relatability is what makes Dr. Seuss’s The Cat in the Hat an enduring childhood favorite. There is definitely tension to be resolved here. The fish senses danger and constantly warns the children not to participate in the cat’s perilous stunts. And later, as the mother’s return becomes more imminent, the children begin to heed the fish’s warning and finally wish to contain the chaos and clean up the mess, but how? While this plot is fantastic enough to fuel any child’s imagination, it also contains a problem with which any child can relate: a mess and the threat of a parent’s disapproval.

Explicit and Implicit Topic Sentences

Similar to thesis statements, topic sentences may be explicit or implicit.

Consider the following paragraph from an essay titled “The Bothersome Beauty of Pigeons,” by author and Boise State writing professor, Bruce Ballenger. It’s important to note that this is a personal narrative essay rather than a more traditional academic essay, but the paragraph provides a good example of an implied topic. In this essay Ballenger takes the time to consider the beauty of pigeons, a bird that’s usually thought of as nothing more than a nuisance. Just prior to this paragraph, Ballenger talks about how he used a fake owl to scare away pigeons on his property. He goes on to explain,

My pigeons moved next door where an elderly couple feed them bird seed and have the time and willingness to clean up after their new charges; so it seems, in this case, things have worked out for everyone. But the large flocks still haunt the piazzas in Florence and Venice, the squares in London, and similar places in nearly every city across the globe. Despite their ability to distinguish between a Van Gogh and a Chagall, pigeons still deposit droppings that deface the great marble statues and facades–the works of art and architecture that are part of our human heritage–and yet people still buy bags of seed for about a dollar and pose for photographs, drenched in doves. Meanwhile, officials in these cities continue, sometimes quietly, to wage war against the birds (“Introduction”).

Here, Ballenger seems to be saying that in spite of the attempts of so many to rid themselves of the pigeons, others are still drawn to them and will feed them and encourage them to come back. His main idea seems to be that the battle against pigeons is a losing proposition, but he doesn’t come out and say so. His message in this paragraph is implied. Do you think this paragraph would be improved with an explicit topic sentence?

EXERCISE 1: Identify the Topic and Focus

Choose a piece of writing, perhaps an essay or some news articles found online, and for each paragraph identify (1) the topic and (2) the more focused idea. Remember, the topic sentence applies more focus to the broader topic to help narrow the scope of the paragraph. For example, the topic of a paragraph might be school lunches. The more focused idea of that same paragraph might be the idea of having students plant school gardens as a way to help incorporate more fresh produce in the menu.

Thesis Statements

A thesis statement defines the scope and purpose of the paper. It needs to meet three criteria: 1. It must be arguable rather than a statement of fact. It should also say something original about the topic.     Bad thesis: Lily Bart experiences the constraints of many social conventions in The House of Mirth . [Of course she does. What does she do with these social conventions, and how does she respond to them? What's your argument about this idea?]     Better thesis: Lily Bart seeks to escape from the social conventions of her class in The House of Mirth , but her competing desires for a place in Selden's "republic of the spirit" and in the social world of New York cause her to gamble away her chances for a place in either world. [You could then mention the specific scenes that you will discuss.] 2. It must be limited enough so that the paper develops in some depth.     Bad thesis: Lily Bart and Clare Kendry are alike in some ways, but different in many others. [What ways?]     Better thesis: Lily Bart and Clare Kendry share a desire to "pass" in their respective social worlds, but their need to take risks and to reject those worlds leads to their destruction. 3. It must be unified so that the paper does not stray from the topic.     Bad thesis: Lily Bart gambles with her future, and Lawrence Selden is only a spectator rather than a hero of The House of Mirth . [Note: This is really the beginning of two different thesis statements.]     Better thesis: In The House of Mirth, Lawrence Selden is a spectator who prefers to watch and judge Lily than to help her. By failing to assist her on three separate occasions, he is revealed as less a hero of the novel than as the man responsible for Lily's downfall. [Note: Sometimes thesis statements are more than one sentence long.] 4. Statements such as "In this essay I will discuss " or "I will compare two stories in this paper" or "I was interested in Marji's relationship with God, so I thought I would talk about it in this essay" are not thesis statements and are unnecessary, since mentioning the stories in the introduction already tells the reader this. Topic Sentences Good topic sentences can improve an essay's readability and organization. They usually meet the following criteria: 1. First sentence. A topic sentence is usually the first sentence of the paragraph, not the last sentence of the previous paragraph. 2. Link to thesis . Topic sentences use keywords or phrases from the thesis to indicate which part of the thesis will be discussed. 3. Introduce the subject of the paragraph. They tell the reader what concept will be discussed and provide an introduction to the paragraph. 4. Link to the previous paragraph. They link the subject of the present paragraph to that of the previous paragraph. 5. Indicate the progression of the essay. Topic sentences may also signal to the reader where the essay has been and where it is headed through signposting words such as "first," "second," or "finally." Good topic sentences typically DON'T begin with the following. 1. A quotation from a critic or from the piece of fiction you're discussing. The topic sentence should relate to your points and tell the reader what the subject of the paragraph will be. Beginning the paragraph with someone else's words doesn't allow you to provide this information for the reader. 2. A piece of information that tells the reader something more about the plot of the story. When you're writing about a piece of literature, it's easy to fall into the habit of telling the plot of the story and then adding a sentence of analysis, but such an approach leaves the reader wondering what the point of the paragraph is supposed to be; it also doesn't leave you sufficient room to analyze the story fully. These "narrative" topic sentences don't provide enough information about your analysis and the points you're making.

Weak "narrative" topic sentence: Lily Bart next travels to Bellomont, where she meets Lawrence Selden again. Stronger "topic-based" topic sentence: A second example of Lily's gambling on her marriage chances occurs at Bellomont, where she ignores Percy Gryce in favor of Selden. [Note that this tells your reader that it's the second paragraph in a series of paragraph relating to the thesis, which in this case would be a thesis related to Lily's gambling on her marriage chances.]

3. A sentence that explains your response or reaction to the work, or that describes why you're talking about a particular part of it, rather than why the paragraph is important to your analysis. 

Weak "reaction" topic sentence: I felt that Lily should have known that Bertha Dorset was her enemy. Stronger "topic-based" topic sentence: Bertha Dorset is first established as Lily's antagonist in the train scene, when she interrupts Lily's conversation with Percy Gryce and reveals that Lily smokes.

Thesis Statement or Topic Sentence?

• High School

Occasionally at IEW our customer service team will receive questions about the differences between topic sentences and thesis statements. Hopefully this blog post will dispel any confusion between the two and empower you to help your students assail the essay in style!

Thesis statements summarize the central position of an entire essay and typically appear at the end of the introductory paragraph. Think of them as guideposts for the entire essay. They provide the reader of the essay an idea of the direction it will take. While beginning essay writers will typically write a single-sentence thesis statement, the thesis can be more than one sentence.

Depending upon the type of essay being written, a thesis statement’s emphasis will vary. In an expository essay, an essay that explains or informs, the thesis will narrow what is being explained. Thesis statements in narrative essays, which are essays that relate a story, paint an overall picture of the story that is being described and as such tend to be more personal in nature. Another type of essay, the argumentative essay, features thesis statements that underscore the writer’s opinion. In contrast, persuasive essays employ a somewhat different approach. In a persuasive essay, the thesis statement is oftentimes replaced with a question. This question serves to entice the reader to continue reading the essay in order to learn the writer’s position.

While you can think of thesis statements as guideposts for an entire essay, think of topic sentences as guideposts for individual paragraphs. Topic sentences appear in the body of the essay and are the first sentence in the paragraph. Not only do topic sentences focus the content in the paragraph, they also support the thesis statement made in the introduction.

So what might thesis statements and topic sentences look in a real-life example? Let’s consider a narrative essay prompt that asks the writer to describe someone who challenged him or her to work hard. A thesis statement might look something like this: “My gym teacher, Mr. Hernandez, never stopped encouraging me to do ‘hard things’ in high school.” This thesis statement helps the reader prepare to read some of the ways that Mr. Hernandez encouraged the writer. The topic sentences would support the thesis. Consider the following potential topic sentences:

• Mr. Hernandez encouraged me to enroll in an honors English class my senior year in high school.
• When he learned of an opportunity to help a family who had fallen on hard times, Mr. Hernandez reached out to me to help organize a clothing drive.
• Once I began to apply to colleges, Mr. Hernandez encouraged me to apply to a selective college and even offered to write a reference letter on my behalf.

These topic sentences all support the thesis of the paper by showing how Mr. Hernandez supported the writer of the essay. In the conclusion of the essay, the writer would reiterate the topics one more time before finishing the paper by emphasizing the most important point that underscores the thesis. That point might be something like this:

Mr. Hernandez saw something in me that I didn’t recognize in myself. He helped me to grow in confidence and take on challenges I would never have considered on my own. I’m excited to say that this next fall I’ll be attending ____________ University as an honors student majoring in English. And I even received an academic scholarship thanks in part to his letter of recommendation. I am so thankful he took the time to help me on my path!

Difference Between Thesis Statement and Topic Sentence

A perfect data arrangement, catchy hook, compelling content, and excellent formatting are the basic requirements for any academic paper. However, these are not all the structural parts that may influence the quality of the text.

Although the magnitude of the thesis statement and topic sentence are frequently underestimated, these are the items that can either contribute to the relevance of the paper or affect the final result. 

No matter if you are an experienced writer or a complete amateur, you should pay due attention to these items. At this point, it is essential to mention that the vast majority of learners are unaware of key peculiarities and specifications on these essay parts, considering them to be interchangeable. 

So, what is the difference between a topic sentence and a thesis statement? This is a prominent question you should ask before you start creating any college-level text. Remember that the key objective of both items is to draw the reader’s attention to the core idea of the text. Nonetheless, the thesis statement emphasizes the key specks of the whole paper, while the topic sentence is used to reveal the quirks of a particular paragraph. 

Basic Definitions: Thesis Statement and Topic Sentence in Detail

While the general idea behind these two definitions is clear from the previous point, it is essential to dive deeper into the characteristics of the items to use them more efficiently. 

The thesis statement is the fundamental stand the writer takes. It incorporated the generalized idea of the essay, including the author’s perspective of the topic and the key points included in the text. Striving to make this part influential, the learner should fixate on the topic, limit it, and narrow it down, presenting only the most significant and appealing info. The scope of this essay part will depend mainly on the length, goal of the writing, and the prospective audience. 

As for the topic sentence, it resembles the thesis but has a much narrower meaning. As the name implies, it introduced the principal theme but is restricted to a particular passage. As you read the topic sentence, you will get detailed info about the essence of the passage, its objectives, and conclusions. Here are the prime specifications of the topic sentence:

• it contains the dominating idea of the passage;
• it is short and concise, but informative and influential;
• it is presented as a first sentence in the paragraph;
• it is descriptive and argumentative;
• it is a declarative sentence that contains relevant and valid information only. 

Core Similarities of the Paper Parts

Before you deal with the critical discrepancies of the topic sentence and thesis statement, you should pay due attention to their similarities. It will help you succeed with academic essay writing and achieve the desired goal. Look through the list of core features that make these items alike:

• they are full sentences that communicate a coherent idea;
• they should show and describe the content;
• they should be neither too broad nor too narrow. 

Thesis Statement vs Topic Sentence: Discrepancy to Mind

When the definitions, specifications, and objectives of the thesis statement and topic sentence are acknowledged, the dissimilarities between these items become obvious. However, if you have failed to grasp the core idea, you have another chance to discover the three peculiarities that make the items different. First of all, it is critical to mention the position, information, and function that can make a significant difference. 

All these points should mandatorily be taken into consideration if the learner strives to make the essay highly appreciated. Double-check your awareness of the sentence place and essence, which may become critical for the success of your work.

Both thesis statements and topic sentences help your audience understand the structure and main ideas of your essay. They differ in a few ways.

1) The thesis statement belongs in the introductory paragraph , while topic sentences belong at the beginning of body paragraphs . An essay will have just one thesis statement, but the number of topic sentences depends on the number of body paragraphs.

2) A thesis statement provides an overview of your entire essay. It contains your claim and your reasons .

Thesis statement = claim + "because" + reasons

Example: Capital punishment should be outlawed because it is immoral and does not deter crime.

claim : Capital punishment should be outlawed

reason #1 : it is immoral

reason #2 : it does not deter crime

3) A topic sentence tells your reader what the paragraph is about. Each reason in your thesis should correspond to a body paragraph.

Example: Capital punishment is immoral.

I know from reading this topic sentence that the paragraph will discuss how capital punishment is immoral.

Bonus Tip: Always revisit your thesis statement before submitting your essay. Make sure the reasons in your thesis match the reasons in your body paragraphs! Often writers will include reasons in their thesis statement only to find that their reasons evolve as they research and write their body paragraphs. If the reasons in your thesis statement don't match the reasons in your essay, your audience will become puzzled and frustrated.

A good way to start a paragraph is with a short, simple  sentence  that introduces the main idea of the paragraph. Teachers often call this a ‘ topic   sentence".

A thesis statement, on the other hand, carries the main idea of your whole essay & therefore your stance for/ against the topic along with only mentioning your reasons.

Topic Sentence - usually at the beginning of every paragraph

Thesis Statement - usually at the end of the first/intro paragraph only

Topic Sentence - gives a glimpse as to what the paragraph will discuss

Thesis Statement - gives a glimpse as to what the entire paper will discuss

In my opinion, a topic sentence just states what the topic of your essay is. For example " The subject of my essay is on how the fashion and beauty industry influences women's body image." With a thesis statement, you need to present a stance on the topic and theory that you are trying to prove or options on how to change the situation. An example of this would be " The subject of my essay is on how the beauty industry negatively impacts women's body image and possible ways that the industry can adopt a more positive image."

Distinguishing Topic Sentence from Thesis Statement

A vital aspect of academic writing is that it should have proper format and technique. All colleges, Universities and higher education programs require the students to submit writing projects. Thus, understanding the differences between a topic sentence and a thesis statement in inevitable, even if you consider buying thesis online.

• Difference in Purposes

In order to have a clear conception of the difference between the topic sentences and thesis statements, their purposes needs to be established.

The purposes of the topic sentences are more specific. For instance, with the topic sentence in second section, it is clear what the next paragraph will discuss.

Thesis statements are broad as they leave space for more points to give support to the paper’s argument. If a thesis statement is mentioned in the previous section, a writer can explain his argument further by adding sub-points and demonstrations.

• Difference in Development

The topic sentence contains the dominating idea on which the paragraph will develop. Usually, the first sentence of each paragraph is the topic sentence. The thesis statement, clearly states the subject to allow it to be broken down into parts. It takes a stand about the subject and it provides the direction by implicitly showing the order in which the essay will develop the points.

• Difference in Idea

The topic sentence’s controlling idea falls in the predicate of the sentence and is the essentially argumentative or descriptive or judgmental part of the sentence.

The thesis statement’s controlling idea is a phrase, word or clause that states the attitude, opinion or stand taken by the writer for the subject. The thesis statement provides the writer the accurate angle to approach his subject.

The topic sentence and the thesis statements are analogous.

• The role that the topic sentence serves to the paragraph, the same role is served by the thesis statement to the entire essay, chapter or book.
• The topic sentence acts to give unity to the paragraph by elaborating a vital point mentioned in the controlling idea of the thesis. The thesis statement on the other hand, acts to give unity to the essay.
• Similarities

The topic sentences and the thesis statements both are focused. Both are neither a question nor a prediction but they are always a single declarative statement. The thesis statements and the topic sentence are integral to the organization of the essay. Each paragraph should have a topic sentence.

With the differences between the topic sentence and thesis statements cleared out, you will be able to craft an excellent piece of write-up.
