Aguano language

Aguano is the extinct language of the Aguano people of Peru. Loukotka identified it with Chamicuro, but Chamicuro speakers say that the Aguano people spoke Quechua.
However, Steward notes that the Aguano had adopted Quechua soon after the Conquest and that their original language is unclassified.
More recently, Campbell & Grondona leave Aguano unclassified due to lack of attestation. According to Glottolog, the language is Arawakan.
