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.

Origin and Etymology of idiom

Middle French & Late Latin; Middle French idiome, from Late Latin idioma individual peculiarity of language, from Greek idiōmat-, idiōma, from idiousthai to appropriate, from idios
