Aikanã is an endangered language isolate spoken by about 250 Aikanã people in the Terra Indígena Tubarão-Latundê reserve of Rondônia, Brazil, where it remains the community's dominant language and is still being learned by children. Its word order is subject-object-verb. Researchers have noted lexical and structural similarities with the neighboring isolates Kanoê, Kwaza and Nambikwara, but the evidence is not strong enough to establish a genealogical family linking them, so Aikanã is classified as an isolate with no confirmed relatives.
Facts
RegionRondônia, Brazil, in the Terra Indígena Tubarão-Latundê and neighboring Terra Indígena Kwazá do Rio São Pedro 1 Speaker CountAbout 250 speakers as of the estimate cited; a related group of nearly 100 further ethnic Aikanã (locally Kassupá) people is recorded separately, though their last fluent speaker died in 2018. Proto-Language StatusAikanã is treated as an unclassified language isolate. Hein van der Voort (2005) found similarities among Aikanã, Kanoê and Kwaza but judged the evidence too weak to establish them as a single demonstrated family; Jolkesky (2016) attributes further lexical similarities with Kanoe, Kwaza and Nambikwara to language contact rather than shared descent, so no proto-language has been reconstructed. 1 In the Other Atlases
