mid-14c., auncyen, from Old French ancien "old, long-standing, ancient," from Vulgar Latin *anteanus, literally "from before," adjectivization of Latin ante "before, in front of, against" (from PIE *anti "against," locative singular of *ant- "front, forehead;" see ante). The parasitic -t dates from 15c. by influence of words in -ent.
