Bridging the fields of youth studies and language planning and policy, this book takes a close, nuanced look at Indigenous youth bi/multilingualism across diverse cultural and linguistic settings, drawing out comparisons, contrasts, and important implications for language planning and policy and for projects designed to curtail language loss. Indigenous and non-Indigenous scholars with longstanding ties to language planning efforts in diverse Indigenous communities examine language policy and planning as "de facto "and "de jure" as covert and overt, bottom-up and top-down. This approach illuminates crosscutting themes of language identity and ideology, cultural conflict, and linguistic human rights as youth negotiate these issues within rapidly changing sociolinguistic contexts. A distinctive feature of the book is its chapters and commentaries by Indigenous scholars writing about their own communities. This landmark volume stands alone in offering a look at diverse Indigenous youth in multiple endangered language communities, new theoretical, empirical, and methodological insights, and lessons for intergenerational language planning in dynamic sociocultural contexts."
