Nonliteral phrases, also known as IDIOMS, are expressions that have a figurative meaning that is different from the literal meaning of the words. IDIOMS are used in everyday language and can be found in literature, movies, and other forms of media. They are often used to convey a certain emotion or sentiment that cannot be expressed with literal language. Examples of nonliteral phrases include 'it's raining cats and dogs, ' 'break a leg, ' and 'biting off more than you can chew.'
