The book I have read is titled Mother Tongue, and it was written by Bill Bryson twenty years ago.
Basically, it is an essay about English and the way this language was growing along the centuries, from its origin to our days, when it has become the most important language in the world. In fact, the author tries to explain to us the different factors that have contributed to get English in the first position above all languages. Furthermore, the book is full of curious details that make reading it quite interesting.
In my opinion, Mother Tongue should be read by all the students who want to learn English because it could help them to understand everything regarding this language in a better way.
