This project supported by the Mexican Academy of Sciences (AMC, CONACyT, and CCC) has two main goals: a) to extend the recent efforts of language documentation on Southeastern Tepehuan (O’dam), and b) to expand the current database with discourse genres that were not captured or were scarce in the first stage of documentation (2010-211). By providing local records on the real situation of the language, we will benefit both the grammatical study of the language, and the possible comparisons with other Uto-Aztecan languages or neighboring languages.
