A formal definition is based upon a concise, logical pattern that includes as much information as it can within a minimum amount of space. The primary reason to include definitions in your writing is to avoid misunderstanding with your audience. A formal definition consists of three parts.

  1. The term (word or phrase) to be defined
  2. The class of object or concept to which the term belongs.
  3. The differentiating characteristics that distinguish it from all others of its class

For example:

  • Water (term) is a liquid (class) made up of molecules of hydrogen and oxygen in the ratio of 2 to 1 (differentiating characteristics).
  • Comic books (term) are sequential and narrative publications (class) consisting of illustrations, captions, dialogue balloons, and often focus on super-powered heroes (differentiating characteristics).
  • Astronomy (term) is a branch of scientific study (class) primarily concerned with celestial objects inside and outside of the earth's atmosphere (differentiating characteristics).

Although these examples should illustrate the manner in which the three parts work together, they are not the most realistic cases. Most readers will already be quite familiar with the concepts of water, comic books, and astronomy. For this reason, it is important to know when and why you should include definitions in your writing.

When to Use Definitions

  • When your writing contains a term that may be key to audience understanding and that term could likely be unfamiliar to them
    "Stellar Wobble is a measurable variation of speed wherein a star's velocity is shifted by the gravitational pull of a foreign body."
  • When a commonly used word or phrase has layers of subjectivity or evaluation in the way you choose to define it
    "Throughout this essay, the term classic gaming will refer specifically to playing video games produced for the Atari, the original Nintendo Entertainment System, and any systems in-between."

    Note: not everyone may define "classic gaming" within this same time span; therefore, it is important to define your terms

  • When the etymology (origin and history) of a common word might prove interesting or will help expand upon a point
    "Pagan can be traced back to Roman military slang for an incompetent soldier. In this sense, Christians who consider themselves soldiers of Christ are using the term not only to suggest a person's secular status but also their lack of bravery.'

Additional Tips for Writing Definitions

  • Avoid defining with "X is when" and "X is where" statements. These introductory adverb phrases should be avoided. Define a noun with a noun, a verb with a verb, and so forth.
  • Do not define a word by mere repetition or merely restating the word.

    "Rhyming poetry consists of lines that contain end rhymes."

    Better:

    "Rhyming poetry is an art orm consisting of lines whose final words consistently contain identical, final stressed vowel sounds."

  • Define a word in simple and familiar terms. Your definition of an unfamiliar word should not lead your audience towards looking up more words in order to understand your definition.
  • Keep the class portion of your definition small but adequate. It should be large enough to include all members of the term you are defining but no larger. Avoid adding personal details to definitions. Although you may think the story about your Grandfather will perfectly encapsulate the concept of stinginess, your audience may fail to relate. Offering personal definitions may only increase the likeliness of misinterpretation that you are trying to avoid.

What is a Definition Essay?

A definition essay is writing that explains what a term means. Some terms have definite, concrete meanings, such as glass, book, or tree. Terms such as honesty, honor, or love are abstract and depend more on a person's point of view.

Three Steps to Effective Definition

  1. Tell readers what term is being defined.
  2. Present clear and basic information.
  3. Use facts, examples, or anecdotes that readers will understand.

Choosing a Definition

Choosing a definition is a key step in writing a definition essay. You need to understand the term before you can define it for others. Read the dictionary, but don't just copy the definition. Explain the term briefly in your own words. Also, it's important to limit your term before you start defining it. For example, you could write forever on the term "love." To limit it, you would write about either "romantic love," "platonic love," or "first love."

Thesis Statement of a Definition Essay

The thesis statement usually identifies the term being defined and provides a brief, basic definition.

(term) (basic definition)

Ex: Assertiveness is standing up for your rights.

How To Write an Effective Definition

  1. Create a definition. There are several ways to define a term. Here are a few options.
    • Define by function. Explain what something does or how something works.
    • Define by structure. Tell how something is organized or put together.
    • Define by analysis. Compare the term to other members of its class and then illustrate the differences. These differences are special characteristics that make the term stand out. For example, compare a Siberian husky to other dogs, such as lap dogs, mutts, or sporting dogs.

      (term) (precise definition)

      Ex: A Siberian husky is a dog reputed for its ability to tolerate cold, its distinctive features, and its keen strength and stamina.

    • Define by what the term does not mean. This distinction can sometimes clarify a definition and help a reader to better understand it.
  2. Use understandable facts, examples, or anecdotes. Select facts, examples, or anecdotes to fully explain your definition. Ask yourself, "Which examples will best help readers understand the term? What examples would most appeal to my readers? Will a brief story reveal the term's meaning?" Do not use any examples that will not support the definition.

Remember: A definition essay is writing that explains what a term means. When writing a definition essay, remember to tell readers what term is being defined, to present a clear and basic definition, and to use facts, examples, or anecdotes that readers will understand

Here are the examples of popular definition essay topics:

  • Kindness
  • Sense of Humor
  • Love
  • ...

Whatever essay topic you choose, you should be interested in the subject and familiar with it. It would be great if you had your personal experience in the matter you are going to define.
