Washo /ˈwɒʃoʊ/ (or Washoe; endonym wá:šiw ʔítlu) is an endangered Native American language isolate spoken by the Washo on the California–Nevada border in the drainages of the Truckee and Carson Rivers, especially around Lake Tahoe. While there are only 20 elderly native speakers of Washo, since 1994 there has been a small immersion school that has produced a number of moderately fluent younger speakers. The immersion school has since closed its doors and the language program now operates through the Cultural Resource Department for the Washoe Tribe. The language is still very much endangered; however, there has been a renaissance in the language revitalization movement as many of the students who attended the original immersion school have become teachers.
