In the Know is the last word on idioms as they are used today. Based on extensive research in the Cambridge International Corpus, it contains 40 four-page units and are grouped by context, by concept, or by key words. Each four-page unit starts out with a presentation page, which is folowed by three sections: Focus on Meaning, Focus on Form, and Focus on Use. A reference section gives definitions and examples from the Cambridge dictionary of American Idioms to give students a resource for checking the idioms they've learned.
