What term is used to describe a word that tells more about a noun or pronoun?

The term that describes a word used to provide more information about a noun or pronoun is an adjective. Adjectives add detail by describing qualities, quantities, or states of being, allowing readers to better understand the characteristics of the nouns or pronouns they modify. For example, in the phrase "the blue sky," the adjective "blue" provides additional information about the noun "sky."

In contrast, an adverb modifies verbs, adjectives, or other adverbs, often describing how, when, where, or to what extent something occurs; it does not directly describe nouns. Antonyms are words that have opposite meanings, which doesn’t apply to the context of describing nouns or pronouns. A biography is a written account of someone's life, which is unrelated to grammatical terms concerning word functions. Thus, the correct identification of adjectives underscores their important role in enriching language by adding descriptive detail.
