Senior moment. Think outside the box. Idioms like these can't be understood just from the words that make them up. The American Heritage® Dictionary of Idioms explores the meanings of idioms, including phrasal verbs such as kick back, proverbs such as too many cooks spoil the broth, interjections such as tough beans, and figures of speech such as elephant in the room. Since the publication of the first edition 15 years ago, author Christine Ammer has made extensive revisions that reflect new historical scholarship and changes in the English language. This second edition defines over 10,000 idiomatic expressions in greater detail than any other dictionary available today. English language learners will find this dictionary especially useful.
