Academic essays at college level are usually argumentative: you develop a clear thesis about your topic and make a case for your position using evidence, analysis and interpretation. Body paragraphs play an indispensable role in proving the essay's thesis, which is presented in the introduction. As a sequence, body paragraphs provide a path from the introduction — which forecasts the structure of the essay's content — to the conclusion, which summarizes the arguments and ways to start an essay looks at how final insights may apply in different contexts. Each body paragraph must therefore relate logically to the one immediately before and after it. To improve the flow of your essay make sure the last sentence of one paragraph links to first sentence of the next paragraph. This will help the essay flow and make it easier to read.
