Twenty years after Edgar W. Schneider’s publication of the Dynamic Model, the field of World Englishes is as vibrant as ever. 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.
