Quick Answer

The difference between well vs good is simple:

Although there are a few exceptions, remembering this basic rule will help you use both words correctly in most situations.

Good is an adjective that describes a person, place, thing, or idea. It tells us about the quality or condition of something.

Examples

• This is a good book.
• She is a good friend.

In every example, good describes a noun.

Common Uses of “Good”

People often use good to describe:

• Quality
• Character
• Performance
• Behavior

Well is most commonly an adverb. It describes how an action happens.

One exception often surprises learners.
