Define the term in the body of the essay, not the introduction.
The purpose of your introduction is to catch the reader's attention and establish your thesis, not to define terminology. If you are worried that you cannot use the term without defining it, use synonyms in your introduction as much as possible. If you feel you must give a lengthy definition to elaborate on the term's various shades of meaning, break it into a few longer sentences.
A definition essay works to provide the nitty-gritty details about a word or concept.
For example, in an art class, you may be asked to write a definition essay on Vermillion (a vivid reddish-orange color) or Cubism, a specific approach to creating art.
Types of places which may be assigned are a country, state, city, neighborhood, park, house, or a room. A key to writing a good definition essay focused on the place is to select a specific place you are familiar with; it shouldn’t be a place you need to research — it should be a place that you know intimately.
An adjective essay focuses on creating a definition for an adjective.
Defining a concept or a notion in the form of an essay is quite common among the students.
This is one of the classic assignments young people get at colleges and universities. And even though they often face the necessity to deal with this task, not all students know how to write a definition essay outline.
When writing an essay, you may need to define some of that terminology that is familiar to you.
Writing a word-for-word definition from the dictionary can be awkward, and putting the definition in the wrong part of your essay can make it seem poorly organized or confusing.
