People who are interested in language or linguistics would definitely love this book. David Crystal explains a number of features of language very nicely in this book. Language is like people, it lives, it changes and it dies. Amazing fact is that all the language are different, yet they are alos similar in some sort of way and those could be explored through this book. In present days, interenet is playing a major role on the language change and that has also been discussed by the author.
The book is easy to read and has lots of illustrations to accompany the discussion. Just like any other encyclopedia, this book is also large in size and heavy. So those who want to read it on their journy by train or by bus, would not find it comfortable. However the book is so interesting that it worth to allocate time just to be with the book and read it properly by sitting on a desk and a chair.
