Heritage Speakers of Spanish and Study Abroad is an edited volume that provides emerging research on heritage speakers of Spanish in immersion contexts in theoretical, empirical, and programmatic terms. This edited collection seeks to expand our understanding of heritage speakers of Spanish by incorporating research on their linguistic, sociolinguistic, and pragmatic development during and after a sojourn abroad, by discussing the complexities of their identity formation and negotiation during immersive stays, and by highlighting programmatic innovations that could be leveraged to better serve diverse learners in study abroad contexts. This volume advances the fields of both heritage language education and research on immersion study in a variety of ways and will be of interest to scholars of applied linguistics, sociolinguistics, second language acquisition, and educational linguistics, especially those interested in study abroad programming and Spanish for heritage speakers.
