Small enough to fit in purse or pocket, this dictionary presents nearly 3000 America 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. Here's a handy reference guide to them for ESL students, foreign travelers in North America, and anybody with an interest in language usage. Expressions are listed alphabetically, identified according to their part of speech, and categorized as informal, formal, slang, or literary. Each expression is defined and supplemented with an illustrative sentence.
