Choose the correct definition for an adjective.

An adjective is defined as a word that describes a noun. This means that adjectives provide additional information about the characteristics, qualities, or attributes of a noun, allowing for a more detailed and vivid description. For example, in the phrase "the red apple," the word "red" is an adjective that specifies the color of the apple, which helps the reader or listener to picture it more clearly.

The primary function of an adjective is to enhance the noun it modifies, adding context such as size, shape, color, quantity, and more. This descriptive capability is what distinguishes adjectives from other parts of speech. For instance, unlike verbs that express action, or pronouns that replace nouns, adjectives focus solely on providing more information about nouns. This characteristic makes option B the correct choice in identifying the role of adjectives in language.
