Tuesday Afternoon Punctuation: Commas, Part VIII—Adjectives

When a noun is preceded by two or more adjectives, sometimes commas are used to separate the adjectives and sometimes they are not. How can you tell when to use commas and when not to? There are a couple of handy tricks to help you figure this out.

When two or more adjectives modify a noun separately, they are called coordinate adjectives. An easy way to tell whether you’re dealing with coordinate adjectives is to insert and between them—if the meaning of the phrase doesn’t change, you’ve got coordinate adjectives, and you should separate them with commas. Alternatively, coordinate adjectives can be rearranged without altering the meaning of the phrase:

Danielle has young, good-looking, hip friends.

Danielle has young and good-looking and hip friends.

Danielle has hip, good-looking, young friends.

However, two or more adjectives that do not modify a noun separately are called cumulative adjectives. Cumulative adjectives piggyback on one another, each modifying the rest of the word group that follows it. They cannot be separated by and or rearranged without changing the meaning of the phrase:

Danielle has many young friends.

Here, young modifies friends, but many modifies young friends. You wouldn’t be able to write many and young or young, many without altering your meaning or just not making sense.

Could You Repeat That?

If the same adjective is repeated for emphasis, use a comma:

Danielle has many, many friends.

Do you have a question about the comma? Let me know, and I’ll include it in a future installment of Mots Justes’ ongoing series.
