Paragraphs and essays both require supporting details that elaborate on the statements made in the topic sentence or thesis statement. In a paragraph, each subsequent sentence builds upon the point made in the topic sentence; in an essay, the first sentence in each paragraph discusses points made in the thesis statement. In a paragraph, the sentences following the topic sentence are called "supporting details." In an essay, the paragraphs following the thesis statement are called "supporting paragraphs." Each supporting paragraph has its own supporting details.
