chiasmus

Chiasmus is a rhetorical device in which words, phrases, or concepts are repeated in reverse order, creating a mirrored structure. It often emphasizes contrast or highlights a relationship between ideas. A famous example is John F. Kennedy's quote: "Ask not what your country can do for you, ask what you can do for your country." Here, the order of the phrases is switched to enhance the message's impact, making it more memorable and persuasive. Chiasmus is commonly found in literature, speeches, and everyday language to create rhythm and deepen meaning.
