As I mentioned above, the classic essay is divided into an intro/thesis, a body of main points with supporting evidence, and a conclusion that repeats the primary thesis. Other sections, like a counterargument, may also be possible. This is a broad guideline: In practice, every argument is different. Writers will also have to decide what evidence or explanations are best for their position, and what information may be distracting or unnecessary for their points. Through the research and outlining process, the structure of the essay should start to become clear before you even begin writing it.
