Which part of speech provides additional information about a noun?

The part of speech that provides additional information about a noun is the adjective. Adjectives are descriptive words that modify nouns by giving more details such as color, size, quantity, shape, or other characteristics. For example, in the phrase "the red apple," the adjective "red" conveys specific information about the noun "apple," helping to clarify and enrich the meaning.

On the other hand, verbs denote actions, conditions, or states of being but do not modify nouns. Conjunctions serve to connect words, phrases, or clauses but are not used to describe or add information about nouns. Prepositions indicate relationships in time and space, linking nouns to other words in a sentence but, similar to verbs, do not modify or give information about nouns themselves. Therefore, the role of adjectives as modifiers makes them the correct answer in this context.
