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. Case studies examine English(es) in England, Namibia, the United Arab Emirates, India, Singapore, the Philippines, South Korea, Japan, Australia, North America, the Bahamans, Trinidad, Tristan da Cunha, St. Helena, Bermuda, and the Falkland Islands, Ireland, Gibraltar and Ghana.
