LINGUICIDE — [Noun] The death of a language, either through natural processes or deliberate political actions. From linguo- (relating to language) + -cide (killing, from Latin caedere "to cut, kill"). Unlike "language attrition" (the slow erosion of fluency in individuals) or "language shift" (the adoption of a dominant tongue while the old one lingers), linguicide is final—a silencing. It is the last speaker of Ubykh exhaling in a Turkish village, the schoolyard punishment for speaking Welsh, the colonial ledger where a scribe records a language’s name and adds, beside it, "extinct." A tongue does not fade; it is murdered, and with it, a way of seeing the world.
