Small enough to fit in purse or pocket, this dictionary presents more than 2,500 American-English idiomatic words and expressions with their meanings. "In one's element" ... "nail down" ... "off base" and most other American idioms are composed of simple words that somehow take on brand-new meanings when they are combined. ESL students, foreign travelers in North America, and anybody with an interest in language usage will find this book to be an informative quick-reference guide.
