What is a cumulative adjective?

A cumulative adjective is part of a list of two or more adjectives that describe a noun or pronoun (e.g., “bright pink hair,” “creepy carnivalesque Polka music”).

Cumulative adjectives are adjectives from different categories (e.g., opinion, size, color, type), so they must be listed in a specific adjective order and should not be separated by commas or “and.”
