How do adverbs function as modifiers?

Adverbs function as modifiers by providing additional information about verbs, adjectives, or other adverbs. They can modify the meaning of a verb by indicating how, when, where, or to what extent an action is performed. Adverbs can also modify adjectives by describing the degree or intensity of a quality. Additionally, adverbs can modify other adverbs by indicating the manner or degree in which an action is performed.
