McGraw-Hill's dictionary of American idioms and phrasal verbs

McGraw-Hill's Dictionary of American Idioms is the most comprehensive reference of its kind, bar none. It puts the competition to shame, by giving both ESL learners and professional writers the complete low-down on more than 24,000 entries and almost 27,000 senses. Entries include idiomatic expressions (e.g. the best of both worlds), proverbs (the best things in life are free), and clich é s (the best-case scenario). Particular attention is paid to verbal expressions, an area where ordinary dictionaries are deficient.

The dictionary also includes a handy Phrase-Finder Index that lets users find a phrase by looking up any major word appearing in it.
