An introduction is the most important part of an essay as it sets the standard and lets the reader know what you have in store for them. Writing a catchy or surprising introduction is a must for a good essay and should leave your audience wanting more.
Gather your material together and review your plan and layout to know exactly what you are going to include in your introduction. It shouldn't contain facts or lots of description as you should save this for the main body.
Start with a question, quotation or surprising and controversial statement that will immediately grab the attention of the reader. Keep in mind that whoever is reading or marking your essay will have many others, so your essay should stand out by grabbing attention from the beginning.
Keep the introduction brief by adopting a light tone and staying away from long-winded explanations. Your introduction shouldn't be a summary of everything in your essay but it should ask the question you are going to answer or explain the problem that you will discuss, without actually doing so.
Use correct language and grammar and avoid slang or paraphrasing unless it directly relates to the topic of your essay. Ensure that the introduction is structurally correct and arranged into manageable sentences and paragraphs. Read it through aloud to check it is easy to follow and the words flow naturally together.
Finish with a final statement or question that should lead naturally and automatically to the main body of your essay. Some people prefer to write their introduction after the essay but if you do this, beware of repeating what is going to follow. Leave your audience with a sense of anticipation that makes them want to continue to the end.
