Does migration preserve a language or hasten its disappearance? How do languages adapt, resist, or die in diaspora compared with life in their homelands? Drawing on twenty-two vivid case studies of more than thirty endangered languages used in Europe, Asia, Latin America, Canada, Africa, and Australia, this book shows how mobility reconfigures transmission, identity, and power. It reveals why diaspora can intensify language loss while also spark creativity and revival. Across these cases, speakers step into new roles as teachers, activists, and digital innovators. For readers seeking to understand how endangered languages survive or fail in a mobile world—across families, institutions, and digital networks—this book offers incisive analysis and fresh perspectives.
