Cambridge Handbook of World Englishes [PDF ebook] 

The plural form 'Englishes’ conveys the diversity of English as a global language, pinpointing the growth and existence of a large number of national, regional and social forms. The global spread of English and the new varieties that have emerged around the world has grown to be a vast area of study and research, which intersects multiple disciplines. This Handbook provides a comprehensive and authoritative survey of World Englishes from 1600 to the present day. Covering topics such as variationist sociolinguistics, pragmatics, contact linguistics, linguistic anthropology, corpus- and applied linguistics and language history, it combines discussion of traditional topics with a variety of innovative approaches. The chapters, all written by internationally acclaimed authorities, provide up-to-date discussions of the evolution of different Englishes around the globe, a comprehensive coverage of different models and approaches, and some original perspectives on current challenges.
