n.1610s, from Latin narrator “a relater, narrator, historian,” agent noun from narrat-, stem of narrare “to tell, relate” (see narration). In sense of “a commentator in a radio program” it is from 1941. v.1748, back-formation from narration or else from Latin narratus, past participle of narrare “to tell, relate, recount” (see narration). “Richardson and Johnson call it Scottish” [OED], a stigma which kept it from general use until 19c. A few mid-17c. instances are traceable to Spanish narrar. Related: Narrated; narrating. A person who tells a story; in literature, the voice that an author takes on to tell a story. This voice can have a personality quite different from the author’s. For example, in his story “The Tell-Tale Heart,” Edgar Allan Poe makes his narrator a raving lunatic.
