Sociocultural linguistics has long conceived of languages as
well-bounded, separate codes. But the increasing diversity of languages
encountered by most people in their daily lives challenges this
conception. Globalization has accelerated population flows, so that
cities are now sites of encounter for groups that are highly diverse in
terms of origins, cultural practices, and languages. New media
technologies invent communicative genres, foster hybrid semiotic
practices, and spread diversity as they intensify contact and exchange
between peoples who often are spatially removed and culturally different
from each other. Diversity--even super-diversity--is now the norm. In
response, recent scholarship complicates traditional associations
between languages and social identities, emphasizing the connectedness
of communicative events and practices at different scales and the
embedding of languages within new physical landscapes and mediated
practices. This volume takes stock of the increasing diversity of
linguistic phenomena and faces the theoretical-methodological challenges
that accounting for such phenomena poses to sociocultural linguistics.
