Which type of word is primarily used to provide detail to verbs?

The correct answer is adverb because adverbs are specifically designed to modify verbs, providing additional detail about how, when, where, or to what extent an action occurs. For instance, in the sentence "She runs quickly," the adverb "quickly" enhances our understanding of the verb "runs" by describing the manner of the action.

Adjectives, on the other hand, modify nouns, giving more information about a person, place, or thing. Pronouns serve to replace nouns to avoid repetition, while nouns represent objects or concepts. Thus, adverbs uniquely fulfill the role of providing essential detail to verbs, making them critical for conveying the full context of an action.
