This revised, updated, and expanded edition defines more than 8000 idiomatic words and phrases of American English. Each alphabetical entry has a grammatical explanation and an example sentence. The dictionary, which includes a preface in nine different languages, is a tool to help increase fluency in English for students, business travelers, and leisure travelers. The dictionary may also be used by native-born Americans who are sometimes confused by colloquial phrases (many of them regional in nature) not readily found in ordinary dictionaries and by non-native Americans whose mother tongue is not English. The dictionary's preface explains what an idiom is, what kinds of idioms there are, and how they work, and provides instructions on how to use the dictionary. The ordering of information in the dictionary includes the parts of the sentence, explanations, examples, and cross-references in alphabetical order on every pertinent page. (NKA)
