In an introduction to an essay you should offer a short, concise summary of the main points to be raised. If appropriate, you could clarify key concepts. Introductions go wrong when students go into too much detail, and then repeat their arguments in the main body of the text. Generally speaking, it is advisable to start off with short sentences, rather than complex sentences. This will help create a clarity of thought and purpose.Although the conclusion paragraph comes at the end of your essay it should not be seen as an afterthought.
