This book is a translation of the US and is very well done.
This book literally fascinated me and I really recommend it to anyone wanting to learn more about the languages and their mechanisms (especially in Western languages but many are more general notion)
The only point that I do not appreciate is that some passages are a little technical and boring to read but fortunately there are few!
Once you read this book you can not see his mother tongue in the same way!
Do not hesitate!
