coordinate adjective

In grammar, an adjective is a word that modifies a noun or pronoun, typically by describing a quality or distinguishing one thing from another. For example, in the phrase "the red car," "red" is an adjective modifying "car".1

Coordinate adjectives are adjectives that modify the same noun independently and are of equal grammatical rank. They can often be separated by "and" or have their order switched without changing the meaning. For instance, "a beautiful, sunny day" uses coordinate adjectives.23

Cumulative adjectives, on the other hand, build upon each other and modify the noun phrase that follows them. They cannot typically be separated by "and" or have their order changed. An example is "a cumulative weight gain".45
