The Waorani (Huaorani) language, commonly known as Sabela (also Wao, Huao, Auishiri, Aushiri, Ssabela ; autonym: Wao Terero; pejorative: Auka, Auca) is a vulnerable language isolate spoken by the Waorani people, an indigenous group living in the Amazon rainforest between the Napo and Curaray Rivers in Ecuador.
A small number of speakers with so-called uncontacted groups may live in Peru.
Other areas where it is spoken include Pastaza and Napo provinces (including the towns of Puyo and Coca), Yasuní National Park, and the Taromenani Tagaeri Intangible Zone.
However, it forms part of Terrence Kaufman's Yawan proposal.
Loukotka (1968) lists the following basic vocabulary items for Sabela and Tiwituey.
