Why do languages lose their last speakers?

Language death occurs when a language loses its final native speaker, a process often driven by cultural assimilation and language shift toward dominant foreign lingua francas. During the modern period following the rise of colonialism, this shift has threatened thousands of minor languages worldwide. While language death involves a speech community losing competence entirely, it differs from individual language attrition.

What we know

• Language death occurs when a language loses its last native speaker, whereas language extinction means it is no longer known even by second-language speakers. [4]
• In the modern period from approximately 1500 CE onward, language death has typically resulted from cultural assimilation leading to language shift in favor of foreign lingua francas. [4]
• Language death is distinct from individual language attrition, which describes a single person losing proficiency in their first language. [4]
• Global mortality reports and statistics track large numbers of human deaths annually, such as tens of millions recorded by organizations like the World Health Organization. [2]
