what is idiomatic expression?

Sagot :

IDIOMATIC EXPRESSIONS Are fixed expressions whose meaning is not literal or obvious. Their meaning cannot be derived from the combined meaning of the individual. It also adds color and life to communication to words or phrases.
Example:
"When Ana receives her birthdaypresent, she will be Over The Moon"

 The idiom over the moon does not mean that Ana is really over the moon. The motion just expresses that she is extremely happy.
