This book draws on 10 years of collaborative sociolinguistic work on the changing conditions of language use. It begins with guiding principles, shifts to empirically driven arguments in urban sociolinguistics, and concludes with studies of (in)securitised communication addressed to challenges ahead.

Ben Rampton is Professor of Applied & Sociolinguistics at King's College London. Using linguistic ethnography and interactional sociolinguistics, his work covers urban multilingualism; youth, ethnicity and social class; conflict and (in)securitization; and language education policy and practice.
