P1-i Use a comma between coordinate adjectives.

coordinate adjectives Two or more adjectives that modify a noun equally and independently: the large, red hat.

If you can change the order of a series of adjectives or add and between them without changing the meaning, they are coordinate and should be separated with a comma.

The comma signals that the adjectives are equal, related in the same way to the word modified.

cumulative adjectives Two or more adjectives that do not modify a noun equally. Instead, one or two of the adjectives closest to the noun form a noun phrase that the remaining adjectives modify: colorful hot-air balloons.

If the adjectives closest to the noun cannot be logically rearranged or linked by and, they are cumulative adjectives and should not be separated by commas.
