Theory:

Idioms are a group of words that are established by usage and are unique to the language. It usually has a different meaning than what it reads. It is a set expression or a phrase, and it does not hold the same meaning when read separately. Idioms do not have literal meanings
Example:
A snake in the grass
In general terms, it has its usual meaning. But when used as an idiom, the meaning refers to a disloyal person who pretends to be good.
 
To come off with flying colours
It means to emerge out with brilliant success, but not the literal meaning of coming out with a colourful display!
