American and British Idioms [PDF ebook] 

Idiom is an expression, the meaning of which cannot be derived literally. It indicates subtle shades of underlying meaning or intention. The Idioms in English can be divided into two broad categories: British Idioms and American Idioms. This book provides its readers with both these types of Idioms. The world has now shrunk into a global village where one has to be conversant with both British and American English.
