50 Common English Idioms and Their Meanings

Idioms are expressions whose intended meaning is not simply the sum of their individual words. For example, let the cat out of the bag means to reveal a secret, not to release an animal. Oxford Learner’s Dictionaries and Merriam-Webster describe this nonliteral quality, though idiom can also refer to a language variety or style. The expressions below are useful in conversation and informal writing, but their tone and familiarity differ. Examples are original; regional labels flag alternatives where relevant.

Choose idioms with the audience in mind

An idiom can make conversation sound natural, but too many can obscure a point. Some are informal, some are associated more strongly with a region, and several can seem dismissive or pointed depending on who hears them. In a formal email, plain wording is often safer; in dialogue or a relaxed message, an idiom may add warmth or character.
