What Is Paragraph Unity?

Paragraph unity means that every sentence in the paragraph supports the main idea introduced by the topic sentence. A unified paragraph stays focused. It does not go off topic, introduce unrelated ideas, or include irrelevant details. If a sentence does not help explain, support, or develop the topic sentence, it breaks the unity of the paragraph and should be removed or revised.

Example:

Supporting Sentence 3:
