any member of a class of words that in many languages are distinguished in form, as partly in English by the ending -ly, or by functioning as modifiers of verbs or clauses, and in some languages, as Latin and English, also as modifiers of adjectives or other adverbs or adverbial phrases, as very, well, quickly. Adverbs typically express some relation of place, time, manner, attendant circumstance, degree, cause, inference, result, condition, exception, concession, purpose, or means.
