Use a comma in between coordinate adjectives; do not use one in between cumulative adjectives.
*I use the term “rule”; however, please know that they are more like guidelines, and once you know and understand this rule, you may chose to break it to create an intentional effect.
Terms to Know:
Coordinate adjectives: adjectives that work separately to describe a noun
Cumulative adjectives: adjectives that work together to describe a noun
The are coordinate adjectives because you can put and between them and switch up the order:

- You could say beautiful and gentle. You could say gentle, beautiful. It passes the tests, so they are coordinate and need a comma between them.
These are cumulative adjectives because they are working together to describe the noun:
They had high expectations of the nearby new Irish couple.
- You couldn’t say nearby and new and Irish. You couldn’t switch the order and say Irish nearby new. It doesn’t pass the tests, so these are cumulative adjectives and do not take a comma between them.
