Writing Definitions

  • A definition is a statement that describes a term.
Example:
The Earth is a planet that has life on it.
  • A definition consists of three parts:
  1. A term
  2. a class word (the group or class to which a term belongs to).
  3. and a characteristic(s) (the most important or significant adjective that well describes the term).
See the example below on how to write a definition statement, or go to http://alothman-b.tripod.com/handout_defini.htm

Here is another example:

The mantle is the layer of the Earth between the crust and the core.
Term: Mantle
Class word: Layer
Characteristic: between the crust and the core.
