An Introduction to the Intra-and Extra-territorial Forces Model in World Englishes
With increasing globalization and localization,English has transformed from being singular to plural.Since the introduc-tion of the concept of World Englishes by Kachru in the 1980s,various theories on World Englishes have emerged.As an extension to Schneider's Dynamic Model,the Intra-and Extra-territorial Forces model proposed by Buschfeld and Kautzsch endeavors to account for the development of Englishes that are affected by foreign rule and those that are not within the unified framework.This model highlights the interplay of these two strands of forces on the evolution of English,thereby enhancing people's understanding of World Englishes.
