Twenty years after Edgar W. Schneider's publication of the Dynamic Model, the field of World Englishes is as vibrant as ever. The further spread and entrenchment of English around the world as a result of globalisation but also localisation tendencies and, in particular, the spread of the language and its multiple varieties through the new media, has led to even further dispersion and contact scenarios, many of which challenge early conceptualisations of the World Englishes paradigm. This volume is dedicated to new perspectives, approaches, and developments in the field, how they fit in with earlier research in the paradigm, how they can be conceptualised, and which challenges they bring along. In addition, the collection showcases some of the methodological diversity in and the transdisciplinary nature of modern World Englishes research.
