Highland Chatino
Highland Chatino is an indigenous Mesoamerican language, one of the Chatino family of the Oto-Manguean languages. Dialects are rather diverse; Ethnologue 16 counts them as three languages as follows:

Eastern Highland Chatino (Lachao-Yolotepec dialect)
Western Chatino (Yaitepec, Panixtlahuaca, and Quiahije dialects)
Nopala Chatino

Neighboring dialects between the three groups are about 80% mutually intelligible; diversity among the three Western dialects is almost as great. For phonological and grammatical details, see Chatino languages, which includes examples from Yaitepec dialect. Phonology
