There are six types of clichés, including:
Ex: A leopard cannot change its spots.
Ex: I will take any port in a storm.
Ex: “Come on down!” (Means the Price Is Right)
Ex: Do not bang your head against a concrete wall.
Ex: He eats like a monster.
Achilles’ heel (weak spot of someone)
As you know that cliché is a worn-out and overused expression, which conveys a popular idea, and all above-mentioned types follow the same pattern, however remember that it is not necessary that all proverbs, catchphrases, idioms, similes and metaphors are clichés.
