A body paragraph is a key component of an essay or written work that develops a specific point or idea related to the main topic. It typically begins with a topic sentence that introduces the main idea, followed by supporting sentences that provide evidence, examples, or explanations. This structure helps to clarify and reinforce the argument being made. In academic writing, body paragraphs often include citations from sources to support claims, making them essential for building credibility. Each body paragraph should focus on a single idea, ensuring that the overall flow of the essay remains coherent and organized, ultimately leading to a strong conclusion.
