Commas with Adjectives

Use a comma if the adjectives are equally important and give similar kinds of information.

Example: It was a cold, windy morning.

Don’t use a comma if the adjectives are not equally important or give different kinds of information.

Example: He was a clever young man.

Note:

To check if adjectives give similar kinds of information or not, put and between the adjectives. (It was a cold and windy morning.)

If adjectives give different kinds of information, the and between the adjectives doesn't sound right. (He was a clever and young man.)
