This study deploys detailed analysis of the language dynamics in the Fort Apache indigenous community in North America to explore deepening global concerns over diminishing linguistic heritages. Moving beyond a narrow focus on linguistic documentation, the author examines the ways in which the linguistic and cultural identities of indigenous populations are subsumed by larger socio–cultural groupings and interests. Nevins provides a much–needed appraisal of the potential conflicts between community members and the educators and scholars who research their unique linguistic heritage. The author believes that the debates surrounding the revitalization of indigenous languages need broadening to include larger questions of social mediation, shifting cultural identities, and evaluation of the low levels of participation among indigenous people in language programs. This engaging ethnography examines these questions, and investigates the language dynamics of the Fort Apache Reservation and the particular effects of the dominant non–indigenous textual models that are inimical to their local interests.  Nevins reveals the community’s historical and contemporary concerns for language documentation, maintenance and revitalization. Her text provides perceptive commentary on the need for language maintenance programs and for flexibility in the face of evolving indigenous languages that reflect wider–scale cultural influences.
