Suyá language

Kĩsêdjê (Suyá, Kĩsêdjê: Khĩsêtjê kapẽrẽ [kʰĩˈsedʒe kaˈpẽɽẽ]) is a Northern Jê language (Jê, Macro-Jê) spoken in Mato Grosso, Brazil. It is closely related to Tapayúna; together, they form the Tapajós branch of Northern Jê.

Kĩsêdjê is closely related to Tapayúna; the common past on the Tapajós River, shared by the Kĩsêdjê and the Tapayúna, is still part of their oral history. Phonological differences between the languages include the reflexes of Proto-Northern Jê *m/*mb, *mr/*mbr, *c (in onsets), *ñ (in codas), and *b (in stressed syllables). In Kĩsêdjê, these consonants are reflected as m/mb, mr/mbr, s, n, and p, respectively, whereas Tapayúna has w ([w̃]), nr ([ɾ̃]), t ([t̪]), j ([j]), and w ([w]) in the same words.
