Cultural definitions for idiom

idiom

A traditional way of saying something. Often an idiom, such as “under the weather,” does not seem to make sense if taken literally. Someone unfamiliar with English idioms would probably not understand that to be “under the weather” is to be sick. (See examples under “Idioms.”)
