Idiom - A group of words (or a single word) which have a meaning that is not understood by combining the standard definitions of the individual words (though that meaning may sometimes be inferred). Idioms are a style or form of (often artistic) expression, characteristic of a particular language, group, subculture, school of thought, generation, or medium (for example, movies and television). Idioms can convey that the current situation being described has a resemblance with past history, and in that sense they may be similar to analogies or metaphors. Learning some key idioms and their usages can help your score.
