This episode is the first part of a two-part miniseries on linguistic anthropologists working with Indigenous communities in Mexico. In conversation with Mario Chávez Peón (CIESAS) and Carolyn O’Meara (UNAM), the episode introduces their research on Indigenous languages, their community-engaged fieldwork, and the activism that grows out of it, from developing writing systems alongside speakers to advocating for the rights and visibility of the communities they work with.
