Webster's New World American Idioms Handbook

Rating:
Summary: Outstanding !
Review: It is a MUST for foreign people wanting to master the English language. It is very didactic, has a lot of practical examples, and it is organized according to topics (idioms for business, idioms for love, idioms to describe emotions, etc). There can be other books with more number of idioms, but they are not didactic. This one has the most important and common. You will not need more.
There are a lot of idioms in the movies and conversations, and now I can understand them.
