An "example" is a demonstration of a principle or concept, often used to clarify a point or model behavior. People use examples in everyday conversation, education, and professional contexts to illustrate ideas.
If you make an example of a person who has done something wrong, you punish that person as a way of warning other people not to do the same thing. Although it was only his first offense, the judge decided to make an example of him and sentence him to prison.
