This book brings together two types of varieties of English that have so far been treated separately: postcolonial and non-postcolonial Englishes. It examines these varieties of English against the backdrop of current World Englishes theory, with a special focus on the extra- and Intra-Territorial Forces (EIF) Model. Bringing together a range of distinguished researchers in the field, each chapter tests the validity of this new model, analyses a different variety of English and assesses it in relation to current models of World Englishes. In doing so, the book ends the long-standing conceptual gap between postcolonial and non-postcolonial Englishes and integrates these in a unified framework of World Englishes.
