Almost half of the roughly 6,900 languages spoken around the world today are endangered. Scarily, the rate of extinction is accelerating and there is a whole lot at stake. Communities around the world are losing their indigenous tongue at an unprecedented rate. The grimmest predictions suggest up to 90% of the world’s languages will have disappeared by the end of this century.A language becomes extinct when its last native speaker dies, and it’s usually the result of its speakers shifting to a lingua franca like English, Arabic or Spanish. This implies choice, but it’s often a history of marginalisation that leads to the change.
