Choose one well-focused topic. Narrow it to be specific. Use reliable online or library sources to do research. Find information that is detailed and accurate to support your topic. Write an outline with an introduction, main points with sub-points and a conclusion. Arrange the points in a logical or chronological order. Number them, use the alphabet or Roman numerals to indicate the points and sub-points, or write a topic sentence for each. Keep only relevant information that strengthens the main topic point and does not detract from it.
Write the introduction. State the main topic and provide an overview of what will be discussed. Make the opening line catching to evoke curiosity and encourage the reader to keep reading. Use a quote, anecdote, or interesting statement. Write a formal introduction for longer essays, explaining the scope, purpose and method.
Write the main body of the essay. Follow the outline, making only minor changes for flow. Present relevant supporting details for each point and sub-point. Use descriptive examples and quotes for emphasis. Do more research if you lack material on a point. Write at least two paragraphs and include different material that flows in a logical manner in each paragraph. Interrelate paragraphs with transitional sentences. Write a paragraph for each viewpoint you discuss in an argumentative essay.
Write a new paragraph of two or three sentences as a conclusion. Use a formal conclusion only for longer essays, summarizing briefly the main ideas. Evoke the introduction. Convince the reader to agree with you in a persuasive essay. Leave the reader with something to consider about your topic. Reread the essay and rearrange the paragraphs or sentences if needed to improve the flow of ideas.
