www.englishclub.com › ref › IdiomsIdioms List An idiom is a group of words in current usage having a meaning that is not deducible from those of the individual words. For example, rain cats and dogs (meaning "rain very heavily") is an idiom; and over the moon ("extremely happy") is another idiom. In both cases, you would have a hard time understanding the real meaning if you did not already know these idioms!
