Cherokee, the sole member of the southern branch of Iroquoian languages, is a severely endangered language. Unlike other members of the Iroquoian family, Cherokee has lexical tone. Community members are concerned about the potential loss of their language, and both speakers and teachers comment on the difficulty that language learners have with tone. This paper provides a brief overview of Cherokee tone and describes the techniques, activities, and results from a collaborative project aimed at building greater linguistic capacity within the Cherokee community. Team members from Cherokee Nation, the University of Kansas, and the University of Oklahoma led a series of workshops designed to train speakers, teachers, and advanced language learners to recognize, describe, and teach tone and how to use this information to document Cherokee. Following a participatory approach to endangered language revitalization and training native speakers and second language users in techniques of linguistic documentation adds to the knowledge-base of the community and allows for the documentation process to proceed from a Cherokee perspective rather than a purely academic/linguistic one. This capacity-building aspect of the project could serve as a model for future collaborations between linguists, teachers, and speakers in other communities with endangered languages.
