Each paragraph's material must be relevant to that notion. In other words, your paragraphs should remind your reader that your thesis and the material in each paragraph are interconnected. A working thesis serves as a seed from which your paper and thoughts will sprout. As you write, make sure that what you're saying is consistent with this seed. Often students think that the structure of their essay is complete once they have written an introductory paragraph and a conclusion. But these two sections are just the beginning! You need to connect the various ideas raised in your paper by using different types of sentences (or paragraphs). Make sure that everything you say relates back to your main idea or theme! Here are some examples of how paragraphs can help build a strong essay: In his book "The Elements of Style", William Strunk Jr. argues that paragraphs should be between six and eight lines long. This helps readers identify important information and gives them time to process what they've read. In academic writing, paragraphs usually consist of three parts: a header, a body, and a footer. The header states the topic for the paragraph and provides a reference for the reader if they need to look up information about it. The body describes the information found in the header and provides evidence for that description.
