Determine the underlying purpose of the essay. This might be mandated by the essay question; it may be inspired by a creative writing session. You will write your essay to serve your underlying purpose. In an essay evaluating the Bronte sisters, your purpose might be to say why you prefer one over the other.
Address the underlying purpose of the essay in the first sentence of your conclusion. English for University recommends thinking about the primary message you want to leave with your audience. For greatest effect, the conclusion should demonstrate the development of the original thought found in the thesis.
Write a few sentences that synthesize the main points you made in your essay. Literacy Education Online says you should concentrate on illustrating how your main points fit together to create a greater picture. A summary of points in a conclusion reminds the reader of what he has read. It also helps to lead you naturally to the final sentence.
Write a final sentence that makes a connection with your reader. Kim’s Korner suggests asking a question that causes your reader to think about the subject in greater depth, adding a personal comment about what you’ve gained from the writing experience, or leaving the conclusion open for the reader’s evaluation.
