The purpose of an explanatory essay essayservice.com/blog/explanatory-essay is to state your viewpoint on an issue. You will need to research the topic and use evidence to back up your point of view. Typically, you will write an introduction, body paragraphs, and a conclusion. Your introduction paragraph should include a strong thesis. It should make the case for your position, explain how it supports the argument, and provide background information. Ideally, it should be informative and entertaining. However, you should also follow academic writing standards. A thesis is the central element of an argumentative essay. The thesis should be logical and simple to understand. If you say “The sky is blue on a sunny day”, it would be too simplistic. Alternatively, it could be a complex and detailed argument that is condensed into a single sentence.
