This book addresses increasingly diverse language learning trajectories in a modern, globalized world, specifically outside of formal classroom situations and with respect to second and additional language practices. This includes, but is not restricted to, intersections of formal and informal learning, computer-mediated contexts as well as family contexts and language learning in multilingual contexts. The book provides a current and specifically anthropological view on the second and additional language acquisition in non-school settings through various studies. It is unique in its focus and scope and is relevant to anthropologists and linguists, who are interested in the intersection of language and culture.
