Chiapanec language

Chiapanec is a presumably extinct indigenous Mexican language of the Oto-Manguean language family believed to have been spoken by the Chiapanec people in the Central Depression of the Mexican state of Chiapas, especially in Chiapa de Corzo. It is closely related to the Mangue language spoken further to the south in Nicaragua and Costa Rica.

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).
