late 15c., from Latin inebriatus, past participle of inebriare "to make drunk," from in- "in" (from PIE root *en "in") + ebriare "make drunk," from ebrius "drunk," probably from PIE root *hegwh- "to drink." Related: Inebriated; inebriating. Also used in 19c. English were inebriacy (1842); inebriant, noun (1808) and adjective (1828); inebriety (1801); and inebrious (1711). Old English used indrencan as a loan-translation of Latin inebriare.
