Dzubukuá language

Dzubukuá (or Kariri), referred to by the community as Kariri-Xocó, is an extinct Karirian language of Brazil. Since 1989, there is a process of linguistic revitalization underway; the Tingui-Botó people claim to use Dzubukuá, their ancestral language, in their secret Ouricuri ritual.

It was spoken on the São Francisco River islands, in the Cabrobó area of Pernambuco.
