This book challenges the traditional view of diasporas as territorialized, bounded, and homogeneous entities. It examines the role of language in the evolution of late modern diasporas through a detailed study of Hungarian diasporic speakers in Catalonia. Based on a four-year ethnographically informed critical sociolinguistic study, the volume introduces a new sociolinguistic theory of diasporization, developed collaboratively with the diasporic speakers. The book presents four perspectives on diasporization: chronotopic, boundary-management, posthumanist, and rhizomatic. These insights offer valuable, multidisciplinary approaches to diaspora studies.
