From Late Middle English extinct (“eliminated, eradicated, extinguished”), from Latin extīnctus, exstīnctus (“extinguished, quenched; destroyed, killed; made extinct”), the perfect passive participles of extinguō, exstinguō (“to extinguish, put out, quench; (figurative) to abolish; to destroy, kill”), from ex- (prefix meaning ‘away; out’) + stinguō (“to extinguish, put out, quench”) (from Proto-Indo-European *stengʷ- (“to push”)). The Middle English word displaced Middle English aqueint, aquenched (“extinct; extinguished”). Doublet of extinguish.
From Middle English extincten (“to extinguish or put out (a fire, light, etc.); to destroy, kill; (figurative) to suppress (an uprising); (law) to quash or stop (legal proceedings); to cancel (a privilege, title, etc.); (medicine) to eliminate or reduce (inflammation, an ulcer, etc.)”), from extinct (adjective) (see etymology 1) + -en (suffix forming the infinitive of verbs).
Either: * from Latin extīnctus, exstīnctus, a noun use of the perfect passive participle of extinguō, exstinguō (see etymology 1); or * from the verb (see etymology 2).
