Dzubukuá language

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

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