Chiapanec
Chiapanec language
Oto-Manguean language of Chiapas, Mexico
Chiapanec is a presumably extinct indigenous Mexican language of the Oto-Manguean language family. The 1990 census[2] reported 17 speakers of the language in southern Chiapas out of an ethnic population of 32, but later investigations failed to find any speakers.[3]
There are, however, a number of written sources on the language. Vocabularies and grammars based on these materials include Aguilar Penagos (2012) and Carpio-Penagos and Álvarez-Vázquez (2014).
It is closely related to Mangue.
