The term idiom refers to a set expression or a phrase compromising two or more words. An interesting fact regarding the device is that the expression is not interpreted literally. The phrase is understood to mean something quite different from what individual words of the phrase would imply. Alternatively, it can be said that the phrase is interpreted in a figurative sense. Further, idioms vary in different cultures and countries. For example, every cloud has its silver lining but it is sometimes a little difficult to get it to the mint. The statement quoted above uses “silver lining” as an idiom which means some auspicious moment is lurking behind the cloud or the difficult time. There is another example. I worked the graveyard shift with old people, which was really demoralizing, because the old people didn’t have a change in hell of ever getting out. In the extract quoted above, graveyard shift is used as an idiom which means the work shift during the night.
