An idiom is defined as an expression that has a meaning different from the literal meanings of its component words. This characteristic is what distinguishes idioms from other types of phrases. For example, the idiom "kick the bucket" does not relate to physically kicking a bucket but rather means to pass away. Understanding that idioms convey meanings that are often culturally specific and require knowledge of the language is essential to grasp their use fully.

While the other options present different types of phrases or figures of speech, they do not encapsulate what an idiom is. A phrase describing a physical action would be more straightforward and literal, not capturing the nuanced, figurative meaning of idioms. Similarly, a synonym for a common phrase does not indicate the unique, often non-literal nature of idioms. Lastly, a figure of speech that makes a direct comparison between two unlike things points to similes or metaphors, which is a different linguistic device entirely. Thus, the distinctive quality of idioms lies in their non-literal interpretations, highlighting why the chosen definition is appropriate.
