What is an idiom?

An idiom is a phrase with a figurative meaning that is different from its literal meaning. This means that the words in the phrase do not convey their usual meaning when combined in a specific way. For example, the idiom "kick the bucket" does not literally mean to kick a bucket; rather, it is a humorous way to refer to someone dying. Understanding idioms requires familiarity with the cultural context in which they are used, as the figurative meaning may not be obvious just by looking at the words themselves. This unique characteristic distinguishes idioms from other forms of expression, making option A the correct choice.
