A word that serves to qualify a verb, an adjective, another adverb, or an entire sentence. More specifically, adverbs indicate manner, time, place, cause, or degree, and answer questions such as "how," "when," "where," "how much."

From L.L. adverbium "adverb," literally "that which is added to a verb," from → ad- "to" + verbum "word, → verb," a translation of Gk. epirrhema "adverb," from → epi- "upon, on" + rhema "verb."

Apivâz, from api-, → epi-, + vâz "word," → verb.
