Xocó language

Xocó (Chocó, Shokó) is a dead and poorly attested language or languages of Brazil that is not known to be related to other languages. It is known from three populations: Xokó (Chocó) in Sergipe, Kariri-Xocó (Kariri-Shoko, Cariri-Chocó) in Alagoas, and Xukuru-Kariri (Xucuru-Kariri, Xucuru-Cariri) in Alagoas. It is not clear if these were one language or three. It is only known from a few dozen words from one Kariri-Xoco elder and three Xukuru-Kariri elders in 1961.Rememberers persisted for some time after that. Xocó proper has only 4 known words.

It was originally spoken along the Piancó River is an area that is now a suburb of Porto Real do Colégio.

In ISO encoding, the language was conflated with the Kariri family as ISO 639-3 [kzw] 'Karirí-Xocó'; Ethnologue does not indicate if this was a conscious decision. The confusion likely arises from the Kariri community referring to Dzubukuá as Kariri-Xocó.
