Status

The last native speaker is believed to have died in the 2000s. During this period, only ten people were estimated to have Akuriyó as a second language. By 2012, only two semi-speakers remained.^[1] There may still be speakers in uncontacted groups, while the language has been replaced by closely related Tiriyó among contacted groups.^[2]

Sepi Akuriyó, one of the last surviving speakers of Akuriyó, went missing 2 December 2018, when a small plane carrying eight people disappeared during a flight over the Amazon rainforest. The search and rescue operation was called off after two weeks.^[3]
