A virtually unknown and extinct Indigenous language of Peru, formerly spoken in Cajamarca Department, is referred to as from its characteristic toponym (also as ). It is known from only three words and is associated with the kingdom of Cuismancu (Guzmango), centred in the province of Contumazá. It may have been related to the HibitoâÂÂCholon languages, and may even be identical to other such languages of the region known solely from their distinctive toponyms such as Chachapoya.
Three words found in a document commissioned by a member of the Cuismancu royal family are attributed to the language by Alfredo Torero. These words are 'lady', 'young girl', and 'female servant'.
