Origin / Etymology

PIE word
*h₁eǵʰs
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.
