Also Known As: thesis statement, thesis sentence, controlling idea

The thesis sentence is the key to most academic writing. This is important and worth repeating:

3. Revise the sentence by using specific terms.

We also know that not all students can write good thesis sentences, and it is one of the reasons why they get low grades on their papers. If you are one of them, if nothing helps you including sample thesis sentences and instructions from your teachers, then let us try to explain you the essentials of creating a good thesis sentence.

4. Further revise the sentence to cover the scope of your essay and make a strong statement.

Like any other sentence, the thesis statement has a subject and a verb. After you have decided upon the subject, write a verb to go with that subject. It should indicate what assertion you are making about that subject. A good thesis statement is clear, restricted, and precise. It must deal with only ONE dominant idea.


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

These are four main steps one should take to write a strong thesis sentence.

A well-organized paragraph supports or develops a single controlling idea, which is expressed in a sentence called the topic sentence. A topic sentence has several important functions: it substantiates or supports an essay’s thesis statement; it unifies the content of a paragraph and directs the order of the sentences; and it advises the reader of the subject to be discussed and how the paragraph will discuss it. Readers generally look to the first few sentences in a paragraph to determine the subject and perspective of the paragraph. That’s why it’s often best to put the topic sentence at the very beginning of the paragraph. In some cases, however, it’s more effective to place another sentence before the topic sentence—for example, a sentence linking the current paragraph to the previous one, or one providing background information.The thesis statement usually appears near the beginning of a paper. It can be the first sentence of an essay, but that often feels like a simplistic, unexciting beginning. It more frequently appears at or near the end of the first paragraph or two. Here is the first paragraph of Arthur Schlesinger, Jr.'s essay Notice how everything drives the reader toward the last sentence and how that last sentence clearly signals what the rest of this essay is going to do.Introduction: the first section of a paragraph; should include the topic sentence and any other sentences at the beginning of the paragraph that give background information or provide a transition.Here are the first two paragraphs of George Orwell's classic essay, "Politics and the English Language" (1946). Which of these sentences would you say is or are the thesis statement of the essay which is to follow? Everything that follows in this essay, then, would have to be something that fits under the "umbrella" of that thesis statement.The following paragraph illustrates this pattern of organization. In this paragraph the topic sentence and concluding sentence (CAPITALIZED) both help the reader keep the paragraph’s main point in mind.The first sentence of the second body paragraph should reflect an even stronger Assertion to support the thesis statement. Generally, the second point listed in the thesis statement should be developed here. Like with the previous paragraph, include any evidence–a quotation, statistic, data–that supports this point after the Assertion. Explain what the evidence means. Show the reader how this entire paragraph connects back to the thesis statement.In a coherent paragraph, each sentence relates clearly to the topic sentence or controlling idea, but there is more to coherence than this. If a paragraph is coherent, each sentence flows smoothly into the next without obvious shifts or jumps. A coherent paragraph also highlights the ties between old information and new information to make the structure of ideas or arguments clear to the reader.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.Rephrase your thesis statement in the first sentence of the conclusion. Instead of summarizing the points you just made, synthesize them. Show the reader how everything fits together. While you don't want to present new material here, you can echo the introduction, ask the reader questions, look to the future, or challenge your reader. Sometimes a writer is more or less specific depending on the reading audience and the effect the writer wants to create. Sometimes a writer puts the angle first and the topic last in the sentence, or sometimes the angle is even implied. You need to gauge your reading audience and you need to understand your own style as a writer. The only basic requirements are that the thesis sentence needs a topic and an angle. The rest is up to you.
