When is a language considered dead?
Language death
when a language loses its last native speaker
In linguistics, language death occurs when a language loses its last native speaker. By extension, language extinction is when the language is no longer known, including by second-language speakers. Other similar terms include linguicide,[1] the death of a language from natural or political causes, and rarely glottophagy,[2] the absorption or replacement of a minor language by a major language.
