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 the action is performed. For example, in the sentence "She runs quickly," the word "quickly" is an adverb that describes how she runs. Adverbs can enhance the meaning of a verb by adding details that clarify the action being taken.

In contrast, the other options focus on different aspects of parts of speech. A word that names an action refers to verbs, which describe the action itself rather than modifying it. A word that describes nouns refers to adjectives, which provide more information about nouns rather than verbs. Lastly, a word that indicates possession relates to possessive pronouns or adjectives, which clearly serve a different grammatical function than adverbs. Understanding the role of an adverb highlights the multifaceted nature of language and its components.
