Coordinate adjectives in English grammar are multiple adjectives used to modify the same noun independently, without requiring a specific order or a comma between them.
These adjectives describe different aspects of the noun and can be rearranged without changing the overall meaning of the sentence.
For example, in “a big, red apple,” “big” and “red” are coordinate adjectives, and you can also say “a red, big apple” with no change in meaning.
Coordinate adjectives provide flexibility in expression and allow for various word orders while maintaining clarity in descriptions.
