What Is An Idiom?

An idiom is a common word or phrase which means something different from its literal meaning but can be understood because of their popular use.

Idioms are not the same thing as slang. Idioms are made of normal words that have a special meaning known to almost everyone. Slang is usually special words or special meanings of normal words that are known only to a particular group of people.

Take some examples of idioms to understand more what it is. “Break a leg” – This is a way to wish someone good luck. “To shed crocodile tears” means to cry about something but without actually caring or another example is “It’s raining cats and dogs” means it’s raining heavily.
