How do I write a good introduction?

An introduction should always clearly set out your intentions for the essay, and perhaps even include a sentence that briefly answers your question from the get-go (a thesis.) It should briefly set out a few main points that you will expand on throughout the rest of your essay, but stay focused and concise; the explanation will come in your main body. Your introduction should only take up about a tenth of your essay. You may also choose to explore some of the key words in the question. Remember: this is your reader’s first impression, draw them in!
