Endangered languages refer to languages that are at risk of becoming extinct in the near future. These languages are typically spoken by a small number of people, often within a specific region or community. Factors contributing to the endangerment of a language can include globalization, increased migration, and cultural assimilation. Researchers in the field of endangered languages work to document, revitalize, and preserve these languages before they disappear. This may involve creating written materials, developing language programs, and working with native speakers to pass on their linguistic knowledge to future generations. Overall, the study of endangered languages is important for preserving cultural diversity, promoting linguistic and cultural rights, and understanding the complex relationship between language, identity, and heritage.
