Aikanã (sometimes called Tubarão, Corumbiara/Kolumbiara, or Huari/Uari/Wari) is an endangered language isolate spoken by about 200 Aikanã people in Rondônia, Brazil. It is morphologically complex and has SOV word order. Aikanã uses the Latin script. The people live with speakers of Koaia (Kwaza).
Aikanã is traditionally spoken in the Terra IndÃÂgena Tubarão-Latundê, where it is still the dominant language. It is also spoken in the Terra IndÃÂgena Kwazá do Rio São Pedro, where Kwazá is traditionally spoken. A few Aikanã families in also reside in the Terra IndÃÂgena Rio Guaporé, but they do not speak the language there. There are nearly 100 ethnic Aikanã (locally known as Kassupá) people, in the Comunidade IndÃÂgena Cassupá e Salamãi, although the final Aikanã speaker there died in 2018.
Van der Voort (2005) observes similarities among Aikanã, Kanoê, and Kwaza, and believes that it is strong enough to definitively link the three languages together as part of a single language family. An automated computational analysis (ASJP 4) by Müller et al. (2013) also found lexical similarities between Aikanã and Kwaza. However, since the analysis was automatically generated, the grouping could be either due to mutual lexical borrowing or genetic inheritance.
Jolkesky (2016) also notes that there are lexical similarities with Kanoe, Kwaza, and Nambikwara due to contact.
