An adverb is a part of speech that modifies verbs, adjectives, and other adverbs by providing information about manner, time, place, degree, or extent. There are different types of adverbs including adverbs of manner which provide information about how something is done, adverbs of place which provide information about where something occurs, adverbs of time which provide information about when something happens, and adverbs of degree which provide information about the extent to which something is done. Adverbs can be regular words ending in -ly or irregular words without this ending.
