Etymology: Before it meant anything about ancestry, the word's root described movement: Old French "avancier" came from "avancer", "to advance", built on "avant", "before". Its Latin source was "abante", "from before", so the core idea is someone who goes ahead of you. That literal sense of going first gave rise to the English sense of a predecessor, a forefather who came before. English borrowed the term from Anglo-Norman French in the late Middle Ages, and it appears in writing as a word for an ancestor or forebear. Dictionaries record it as rare and archaic, and it fell out of ordinary use centuries ago. The exact dates and spelling variants are less well documented than those of common words, so the precise first attestation is uncertain. Its modern relative "advance" kept the original sense of moving forward, while this rarer form carried the idea into family history.
