Commas with Paired Adjectives
Coordinate Adjectives
If two adjectives modify a noun in the same way, place a comma between the two adjectives. These are called coordinate adjectives.
There is a two-part test for coordinate adjectives:
(1) Can you replace the comma with the word and?
(2) Can you reverse the order of the adjectives and keep the same meaning?
If you can do both, then you have coordinate adjectives.
