The best definition of an idiom is a phrase containing figurative language in which the word expresses a different idea from its exact meaning.

The best definition of an idiom is a phrase containing figurative language in which the words express a different idea from their exact meaning. This means that idioms are expressions that can't be understood just by knowing the individual words' definitions. Instead, their meaning is derived from the context and cultural understanding surrounding them. For example, the idiom "kick the bucket" does not literally mean kicking a bucket, but rather it means to die. Similarly, the idiom "bite the bullet" does not mean to actually bite a bullet, but it means to face a difficult or unpleasant situation with courage. Idioms add color and depth to a language.
