This is one of the many types of essays that students are asked to write in the colleges. Now, while some other essays may simply entail deep thinking about things to give other people’s opinions and come up with your own opinion at the end of it all, this one takes an entirely different pedestal. When you are asked the question, what is a classification essay , you should start by defining the essay. This is one essay where a writer organizes, sorts and places things into different categories. One thing about this type of essay is that you may be given the classes or categories to place them in, while in some cases, you may be left to make use of your discretion to know the categories that are involved. In this case, the listing of the classes and categories is one of the major parts of the essay that is graded. This may be in the form of any type of paper.
