Reports that American English are ruining English English have been greatly exaggerated. This fun and informative look at the differences between the two languages (and the hows and the whys behind how they came to be thought of as so very different) is the subject of this book by American-born UK-living linguist Lynne Murphy. She does the research and looks into the claims and concludes that, hey, both languages are good and bad in different ways but it’s certainly not true that American changes to the English language are in any way the only negative influence on how people speak today.
