Aikanã (sometimes called Tubarão, Corumbiara/Kolumbiara, or Huari/Uari/Wari) is an endangered language isolate spoken by about 250 Aikanã people in Rondônia, Brazil. It has SOV word order. Aikanã uses the Latin script. The people live with speakers of Koaia (Kwaza).

Demographics

Aikanã is traditionally spoken in the Terra Indígena Tubarão-Latundê, where it is still the dominant language. About 250 people speak the language. It is also spoken in the Terra Indígena Kwazá do Rio São Pedro, where Kwazá is traditionally spoken. The language is currently being learned by children and used sometimes in school. A few Aikanã families in also reside in the Terra Indígena Rio Guaporé, but they do not speak the language there. There are nearly 100 ethnic Aikanã (locally known as Kassupá) people, in the Comunidade Indígena Cassupá e Salamãi, although the final Aikanã speaker there died in 2018.

Name

The name Huari originates from the Guarasu language, meaning 'Indian', and is not recognized by the Aikanã. The names Massaká and Kassupá are the names of important family heads originating from different Aikanã settlements. Tubarão is a corruption of the name Gubal’um, a Salamãi (Mondé) man who became an influential figure in the Aikanã after he married into them. Aikanã is also known by the name of the Corumbiara River.

Classification

Hein van der Voort (2005) observes similarities among Aikanã, Kanoê, and Kwaza, but believes that it is not strong enough to definitively link the three languages together as part of a single language family.

Jolkesky (2016) also observes lexical similarities with Kanoe, Kwaza, and Nambikwara, which he claims is due to contact.
