The book provides a detailed description of the grammar of Teotitlán del Valle Zapotec, an endangered Mesoamerican language spoken in Oaxaca, Mexico. It also contains rich vocabulary and discussions on typologically interesting phenomena like the encoding of agents by stem alternation and complex interactions between tone and phonation, as well as topics in semantics such as the expression of location and the relevance of the posture of entities in existential predication.
