Explanation:
An adverb is a part of the sentence that complements a verb, an adjective, other adverbs and even sentences. Adverbs express circumstances, such as mode, place, time, quantity, affirmation, doubt, etc., answering questions such as when, where, how, how, among others.
The adverb implies that the main function of adverbs is to act as modifiers or complements of a verb or verbal phrase. An adverb used in this way can give information about the mode, place, time, certainty, or other circumstances of the activity expressed by the verb or verbal phrase.
Adverbs are also used as modifiers of adjectives, and other adverbs, usually to indicate degree.
