A tour de force. The book includes discussions of all the latest trends, such as multilingualism on the internet and urban youth language, and weaves them seamlessly into existing research traditions. It covers a whole gamut of social and individual aspects of the subject with clarity, erudition, and panache. It is a first-class teaching tool, offering relevant discussion points after each chapter. Above all, it is a pleasure to read. Penelope Gardner-Chloros, Birkbeck, University of London sakriti opis
