Chiasmus: Definition & 30+ Memorable Examples

Chiasmus (pronounced ky-AZ-mus) is a rhetorical device in which two or more clauses are balanced against each other by reversing their structure. The pattern is often described as A-B-B-A: the first clause introduces elements in one order, and the second clause flips them. The result is a sentence that feels balanced, memorable, and often profound — which is why chiasmus has been a favorite tool of speechwriters, poets, and philosophers for thousands of years.

Chiasmus vs Antimetabole

These two terms are often used interchangeably, but there is a technical distinction:

In practice, most people use "chiasmus" for both forms, and most famous examples (JFK, Mae West) are technically antimetabole. For writers, the distinction matters less than the technique: the power of the reversal.

Famous Examples of Chiasmus

• "Ask not what your country can do for you — ask what you can do for your country."

  John F. Kennedy, Inaugural Address (1961)

  Perhaps the most famous chiasmus in English. The reversal of "country/you" creates a memorable call to civic duty.

• "It's not the men in your life that counts, it's the life in your men."

  Mae West, I'm No Angel (1933)

  Mae West was a master of chiasmus — the reversal creates wit, surprise, and innuendo in a single sentence.

• "Fair is foul, and foul is fair."

  Shakespeare, Macbeth

  The witches' chiasmus establishes the moral inversion that defines the entire play. What appears good is evil, and what appears evil is good.

• "By day the frolic, and the dance by night."

  Samuel Johnson, "The Vanity of Human Wishes"

  A structural chiasmus: activity-time / time-activity. The reversal gives the line its rhythmic elegance.

• "We shape our buildings, and afterwards our buildings shape us."

  Winston Churchill

  The chiasmus makes a philosophical point memorable: the relationship between people and their environments is reciprocal.

• "One should eat to live, not live to eat."

  Attributed to Socrates (via Cicero)

  The reversal sharpens a moral argument about moderation. The chiastic structure makes the contrast impossible to miss.

• "In America, you can always find a party. In Soviet Russia, the party always finds you."

  Yakov Smirnoff (adapted)

  Comedy frequently uses chiasmus — the reversal is the joke's punchline structure.

• "When the going gets tough, the tough get going."

  Proverb (popularized by Joseph P. Kennedy)

  The reversal of "going/tough" creates a motivational statement that feels inevitable and true because of its symmetry.

• —"Success is getting what you want. Happiness is wanting what you get." — Dale Carnegie
• —"Some men are alive simply because it is against the law to kill them." — E.W. Howe (not chiasmus, but often mistaken for one — included to illustrate the difference)
• —"You can take the boy out of the country, but you can't take the country out of the boy." — Common saying
• —"Never let a fool kiss you or a kiss fool you." — Joey Adams

Why Chiasmus Is So Effective

It creates memorability

The A-B-B-A structure creates a satisfying symmetry that the brain latches onto. This is why chiasmus is the backbone of so many slogans, proverbs, and quotable lines. The structure itself does half the work of making the sentence stick.

It implies depth

By reversing two ideas, chiasmus suggests a relationship between them — that they are connected, reciprocal, or paradoxically intertwined. "Beauty is truth, truth beauty" doesn't just state an equivalence; the chiastic structure makes the equivalence feel inevitable and philosophical.

It creates contrast

The reversal highlights the difference between two perspectives, conditions, or choices. JFK's chiasmus works because the two sides of the reversal represent two different orientations toward citizenship — receiving vs. contributing. The structure makes the contrast sharp and unavoidable.

How to Craft Chiasmus in Your Writing

Start with a relationship between two ideas

Chiasmus works best when two concepts have a meaningful relationship — cause and effect, appearance and reality, giving and receiving. Identify the pair first, then experiment with reversing the structure.

Keep it concise

The best chiasmus is tight. Long, complex clauses dilute the impact of the reversal. Aim for short, punchy phrases where the flip is immediately apparent.

Use it for dialogue and internal monologue

In fiction, chiasmus works beautifully in the mouths of witty, philosophical, or rhetorical characters. A character who naturally speaks in chiasmus comes across as sharp-minded, perhaps performative, possibly manipulative — the device itself becomes characterization.

Don't force it

A chiasmus that doesn't say something meaningful is just a word trick. "She opened the door and the door opened her" sounds chiastic but means nothing. The reversal must illuminate a genuine insight or tension.
