Remember that the introduction denotes the first paragraph of your essay that should be a short paragraph in which you should develop the points related to the subject of your essay. It should make the reader interested in having a further look at your piece of writing. Do not forget that the main body of your essay should contain two or more paragraphs where you should develop all the points related to the subject of your essay. In the conclusion of your essay you are to summarize the major idea of the subject and make general comments to your piece of writing.
Division of an essay into paragraphs helps to add a visual dimension of coherence and structure to the essay. If one has a few major points, then each point can be dealt with in separate paragraphs. An essay should also have an introduction and a conclusion. The introduction should clearly set out ones goal or argument, then one should make ones argument and finally, the conclusion should sum up the arguments that one has made.
