Which type of word describes a noun?

The correct choice is the word that describes a noun, which is an adjective. Adjectives serve the purpose of providing more information about a noun, such as its qualities, quantities, or states. For instance, in the phrase "red apple," "red" is an adjective that describes the noun "apple" by indicating its color.

In contrast, the other options serve different grammatical functions. Adverbs modify verbs, adjectives, or other adverbs, providing details about how an action is performed or the degree of an adjective. Collective nouns refer to a group of individuals or items, such as "flock" or "team," but do not describe the characteristics of a noun. Pronouns are used to replace nouns, helping to avoid repetition in sentences, like "he," "she," or "they." Understanding these distinctions highlights the unique role that adjectives play in language.
