The Makeup of Idioms

If you had never heard someone say "We're on the same page," would you have understood that they weren't talking about a book? And the first time someone said he'd "ride shotgun", did you wonder where the gun was? A modern English-speaker knows thousands of idioms, and uses many every day. Idioms can be completely ordinary ("first off", "the other day", "make a point of", "What's up?") or more colorful ("asleep at the wheel", "bite the bullet", "knuckle sandwich"). A particular type of idiom, called a phrasal verb, consists of a verb followed by an adverb or preposition (or sometimes both); in make over, make out, and make up, for instance, notice how the meanings have nothing to do with the usual meanings of over, out, and up.
