This volume offers both insider and outsider perspectives about metalinguistic communities, using concepts such as linguistic objectification, ethnolinguistic infusion, linguistic reindigenization, nostalgia socialization, and raciolinguistics, among others, by which speakers of minoritized languages show enthusiasm for their language and differentiate themselves from outsiders, and how outsiders differentiate against insidersthus foregrounding speakers agency. Linguistic anthropologists, sociolinguists, and anyone working on language revitalization and second language acquisition will find the volume helpful.
