This chapter begins by contextualizing the development of World Englishes as a relatively new field of study. First, in showing that there are many Englishes, not just one, the work of Braj Kachru is reviewed and the importance of his contributions are summarized. Next, debates concerning the motivations for language change in New Englishes are reviewed and examples of a few innovative linguistic features in those varieties are provided. Then we consider the developmental stages in the emergence of New Englishes. Finally, we discuss recent developments, including the role of English as a Lingua Franca (ELF) and the influence of new technology.
