What is an adverb?

An adverb is defined as a word that modifies a verb, providing additional information about how, when, where, or to what extent an action is performed. For example, in the sentence "She runs quickly," the word "quickly" is an adverb that describes how she runs. Adverbs can also modify adjectives or other adverbs, which makes them versatile in enhancing the meaning of sentences.

While some options focus on different types of words: one describes a noun, another expresses an action, and one pertains to pronouns, they do not accurately capture the role of adverbs. An adverb specifically influences verbs, making the understanding of its function critical in constructing clear and precise sentences. Understanding this distinction helps to clarify sentence structure and improves overall writing skills.
