Pankararú has no proven relatives and remains unclassified. Meader (1978) found that of 80 known lexical items, 26 are clearly cognate with Tupian languages. He speculates that the last speakers of Pankararú may therefore have been bilingual in Tupi. The identity of the rest of the vocabulary has not been identified, and Pankararú may be a
language isolate. Loukotka (1968) also lists these languages as being formerly spoken in
Tacaratu,
Pernambuco State. It is not known whether or not they were related to Pankararú: – village of Pindaé near Brejo dos Padres in Tacaratu, Pernambuco. Survivors now speak only Portuguese. •
Macarú – village of Brejo dos Padres, Tacaratu. A few survivors now speak only Portuguese. The original languages of the
Koiupanká and
Karuazu may have been related or identical to Pankararú.
Kalankó (
Cacalancó), with descendants now living in
Água Branca, Alagoas, may have also been related to, or identical with, Pankararú. ==Vocabulary==
