An adverb is a word that modifies or describes a verb, adjective, or other adverb by indicating manner, place, time, frequency, or degree. Some common types of adverbs include adverbs of time that indicate when something occurs (e.g. today, tomorrow), adverbs of place that indicate where something occurs (e.g. here, there), adverbs of manner that describe how something is done (e.g. quickly, loudly), and adverbs of frequency that indicate how often something occurs (e.g. usually, never). Examples are provided to illustrate each type of adverb.
