English idioms
An English idiom is a phrase or expression that has a figurative meaning that is different from the literal meaning of the individual words.
Idioms are commonly used in everyday English conversation, and they add color and variety to the language.
For example:
break a leg (means “good luck”)
raining cat and dog (means “raining very heavily”)
kick the bucket (means “to die”)
cost an arm and a leg (means “very expensive”)
