Abstract
The chapter provides an overview of the developments in synchronic and diachronic corpus-linguistic research into World Englishes (WE), detailing methodological concerns such as sampling frames, representativeness, corpus size, and statistical modelling on the one hand and the broadening scope of corpus-based research from ENL to ESL and EFL varieties on the other hand. It also surveys areas in which corpus-evidence has been applied in the study of WE (e.g. as a testing bed for models of WEs, for the study of language contact, typology and change or as a source of evidence for sociolinguistic and pragmatic variation), providing ample illustration from seminal research papers and recent studies in the field.
