A good paragraph has unity; that is, it discusses only one idea, or topic. The topic sentence states the main idea and provides a scaffold to structure your document. Your writing will be easier to read if you make the topic sentence explicit and put it at the beginning of the paragraph.

The reader knows from the outset what your main point is so they are prepared to receive the evidence you provide to back up your idea.
