Etymology - The word relative derives via Old French from the Late Latin relativus, having reference or relation.
Note: When the word relative entered the English language (circa the 14th century), it specifically denoted the relative pronoun. The first recorded citation for the word in the sense "person from the same family" is from several centuries later (1657).
