What type of word functions primarily to describe a noun?

An adjective is a word that functions primarily to describe or modify a noun. It provides additional information about the noun, such as its qualities, quantities, or states. For example, in the phrase "the tall building," the adjective "tall" describes the noun "building" by providing information about its height. Adjectives enhance our understanding of nouns, allowing for more vivid and precise communication.

In contrast, a verb conveys action or a state of being, a noun refers to a person, place, thing, or idea, and an adverb modifies verbs, adjectives, or other adverbs by providing information about how, when, where, or to what extent something happens. Each of these parts of speech plays a distinct role in sentence structure, but when it comes to describing nouns specifically, adjectives are the words that fulfill this function.
