Body Paragraphs and Topic Sentences


Body paragraphs present a linked series of ideas from which your paper is constructed. To help your reader see how the evidence in each paragraph serves your main idea or argument, begin each paragraph with a topic sentence. A topic sentence should not only identify the paragraph’s main idea but also implicitly or explicitly relate to the argument put forth in your thesis statement.

The remainder of the paragraph then supports the idea expressed in the topic sentence, describing your reasoning and offering well-explained evidence for that idea.

Ideally, if a reader carefully reads your introduction, the topic sentence of each paragraph, and your conclusion, they should understand not only your main argument or claim but how you construct the evidence and support for that claim, piece by piece.

In order to clearly see how each piece of your argument fits together, it is important that the reader can pick apart the boundaries between the individual ideas and chunks of information you use to build your discussion. Therefore, paragraph length matters, and paragraphs that are too long can make your paper harder to follow. Often a paragraph that runs longer than a page should be broken apart to mark the distinct ideas it contains.

A few topic sentence tips:

  •  Avoid using a quotation as a topic sentence. Your topic sentences should be in your voice. They should reflect your ideas.
  • Avoid starting a paragraph with a sentence that summarizes an event; this is a simple statement of fact rather than an analytical statement.
  • Complete a topic sentence reverse outline when you want to assess the strength and clarity of your argument.
