This book is a ground-breaking investigation into recent developments in the English language. The data underpinning the book has been rigorously collected and meticulously analysed, and Cogo and Dewey's wealth of original examples of ELF lexicogrammar and pragmatics will provide an invaluable resource for students and researchers of ELF alike for years to come. Meanwhile, the authors' penetrating discussions of the processes and motivations involved in ELF communication challenge tired old equations of proficiency with nativeness, and cast important new light on what it means to be proficient in English in our increasingly globalized world.

Alessia Cogo and Martin Dewey ... provide a very timely book, which will serve as an introduction to the field for interested linguists and non-linguists alike ... The authors are to be commended for setting out the ELF position in such a clearly structured, well-written and convincing ... manner.
