Book excerpt: This book explores the instrumentality of language in constructing identity in contemporary society. The processes of globalization, hyper-mobility, rapid urbanization, and the increasing desire of local populations to be linked to the global community have created a pressing need to reconfigure identity in this new world order. Following the digital revolution, both traditional and new media are dissolving linguistic boundaries. The centrality of language in organizing communities and groups cannot be overstated: our social order is developed alongside our linguistic allegiance, shared narratives, collective memories, and common social history. Keeping in mind the fluidity of identity, the book brings together fourteen chapters providing cultural and social perspectives. The ideas reflected here draw on a range of disciplines, such as psychology, sociology, anthropology, cultural studies, the politics of language, and linguistic identity.
