Question

identify coordinate adjectives that should be separated by a comma by placing each phrase in the correct category. her deep green eyes a long difficult test the quick sneaky fox that rich delicious meal a brown leather couch coordinate adjectives not coordinate adjectives

Explanation:

Coordinate adjectives are equal in rank, can be reordered or joined by "and" without changing meaning, requiring a comma. Non-coordinate adjectives are not interchangeable, with one modifying the combined phrase of the other and the noun.

1. a long difficult test: "long" and "difficult" can be reordered ("a difficult long test") or joined by "and" ("a long and difficult test") without altering meaning, so they are coordinate.
2. the quick sneaky fox: "quick" and "sneaky" can be reordered ("the sneaky quick fox") or joined by "and" ("the quick and sneaky fox") without changing meaning, so they are coordinate.
3. that rich delicious meal: "rich" and "delicious" can be reordered ("that delicious rich meal") or joined by "and" ("that rich and delicious meal") without altering meaning, so they are coordinate.
4. her deep green eyes: "deep" modifies the phrase "green eyes" (it describes the shade of green, not an equal trait), and reordering ("her green deep eyes") does not make sense, so they are non-coordinate.
5. a brown leather couch: "brown" modifies the phrase "leather couch" (it describes the color of the leather, not an equal trait), and reordering ("a leather brown couch") does not make sense, so they are non-coordinate.
