Etymology

The word "adviser" originates from the Old French "aviser" (to consider, advise), which itself derives from the Latin "ad-" (to) + "visum" (seen, from "videre," to see). The suffix "-er" denotes an agent, forming a noun meaning "one who advises." The spelling "adviser" (also "advisor") reflects the verb "advise," with the "-er" suffix common in English for occupational or role-based nouns. The word retains its core meaning of someone who provides guidance or recommendations.
