Day 88: A one-sentence paragraph should present a complete idea.

Paragraphs can be written many ways. In nonfiction documents, a paragraph may first establish context, provide supporting details, and conclude with an impact statement that leads to the next idea.

In fiction or narrative documents, for another example, a paragraph may show a single action or provide a character’s immediate response to an experience. Some writers use long paragraphs to fully explore an idea, while others may prefer short, terse paragraphs.

In all cases, however, the purpose of a paragraph is to present one idea to the reader. The complexity of the idea and the reader’s need for explanation determine paragraph length. A careful writer will balance the reader’s need with his or her style preferences.

This brings us to a question I have been asked occasionally. How many sentences should be in a paragraph? The answer I give is based on the “one idea per paragraph” concept: at least one.

If the preceding paragraphs have provided sufficient information for the reader to understand the idea, and if the connections between the ideas are clear, and if the value and implications of the idea will be obvious to the reader, one sentence may be sufficient.
