<em>A Paragraph is described as a section or piece of writing that deals with the one central idea or theme.</em>An author shifts paragraphs to shift from one idea to another or link two ideas together. Thus, a group or accumulation of a group of sentences that develops or emphasizes one main idea or theme is treated as a paragraph.
<em>While after presenting the topic, the rest of the content of the paragraph is termed as the body which follows the topic and the introduction of the essay.</em> The body provides details and information about the topic to the readers. It substantiates the key idea as reflected in the topic.
