Idioms are expressions that usually cannot be understood by defining the separate words. Most idioms don't seem to make any sense because their origins are so old. Some of them come from ancient literature or even classic films. Learning the background of idioms can help you to remember them. . For example, if your host mother says, "I think it's time to hit the hay", she means, "I think it's bed-time"! You would not be able to understand her by looking up the words hit and hay. Like phrasal verbs, these expressions need to be memorized as a whole. Try visualizing them or drawing pictures when you study them.
