Chiasmus is a rhetorical device in which words, phrases, or concepts are repeated in reverse order. This structure creates a mirror-like effect, enhancing the meaning and impact of the statement. A classic example is the phrase, "Never let a Fool Kiss You or a Kiss Fool You," where the arrangement of words emphasizes the relationship between the ideas.
Often used in literature and speeches, chiasmus can make language more memorable and engaging. It is found in various works, including those of John F. Kennedy and William Shakespeare. By reversing the order of elements, chiasmus encourages deeper reflection on the ideas presented.
