Apurinã language

Apurina is a Southern Maipurean language of the Arawakan family with active-stative syntax, spoken across roughly twenty-seven indigenous territories along the Purus River in Brazil's Amazonas state by the Popikariwakori, or Apurina, people. About 2,000 fluent speakers were documented in 2012 out of a total indigenous population of roughly 9,500, though fewer than 30 percent of the Apurina population can speak the language fluently. UNESCO classifies Apurina as Definitely Endangered, meaning adults still use it while children lack adequate exposure because schooling is conducted in Portuguese or Spanish instead, a decline compounded by historical conflict, disease and social pressure against Indigenous identity.
