Human language has changed in the age of globalization: no longer tied to stable and resident communities, it moves across the globe, and it changes in the process. The world has become a complex ‘web’ of villages, towns, neighbourhoods and settlements connected by material and symbolic ties in often unpredictable ways. This phenomenon requires us to revise our understanding of linguistic communication. In The Sociolinguistics of Globalization Jan Blommaert constructs a theory of changing language in a changing society, reconsidering locality, repertoires, competence, history and sociolinguistic inequality.
