The structure of an essay begins with the introduction which is the first paragraph and it introduces the topic. It should include naming the main components of the answer. It should be at least 4 – 5 sentences. It tells the reader what the essay is about and mentions the main points. Then the body of the essay elaborates on each of the main points and it is at least 3 or 4 paragraphs of at least 4 – 5 sentences. The last paragraph of an essay is the conclusion and it is a summary of the main points of the essay. Before you write the conclusion, go back and read the question, then write the conclusion, summarizing the main points of the answer. It should be a full paragraph, usually 4 – 5 sentences.
