A saying that means something different from its literal interpretation is called an idiom. One common example is “it’s raining cats and dogs.” This phrase does not mean that actual cats and dogs are falling from the sky; rather, it means that it is raining very heavily.
Another example is “bite the bullet.” This saying does not involve any actual biting; instead, it means to face a difficult situation with courage and determination.
Idioms often reflect cultural contexts and can vary widely between different languages and regions.
