This type of essay will normally consist of three main parts: introduction, body and conclusion. Introduction should contain that hook that will catch and keep your readers’ attention till the last word. Body is the main part in the paper. It may have 3-5 paragraphs where you present your proofs of your opinion. In conclusion you summarize everything you wrote above and make a statement. It is great if your final part contains call for action.
You will find a lot of similarities between persuasive and argumentative papers. The difference is that in an argumentative essay you have to prove your point of view which is opposite to the point of view of the author of the source text.
