20 Rhetorical Devices Every Writer and Speaker Should Know

Why do some lines from speeches stay with us for decades while others are forgotten before the applause ends? Often, the answer is rhetorical devices: deliberate patterns of language that make ideas more memorable, persuasive, or moving.

Rhetorical devices aren’t decoration. Used well, they help an audience follow an argument, feel its importance, and remember it afterward. This guide explains twenty of the most useful devices, with clear definitions, well-known examples, and advice on using each one in your own essays and speeches.

Before the Devices: The Three Appeals

Rhetoric traditionally identifies three modes of persuasion, described by Aristotle:

Ethos: appeal to the speaker’s credibility and character
Pathos: appeal to the audience’s emotions and values
Logos: appeal to logic, evidence, and reasoning

Rhetorical devices are the tools that deliver these appeals. A well-placed rhetorical question can stir emotion (pathos); a careful analogy can clarify reasoning (logos). For more on the appeals, see our guide to writing a persuasive essay.

Devices of Repetition

Repetition is the most powerful tool in spoken rhetoric, because listeners can’t reread. Repeating a word or structure helps them remember.

1. Anaphora

Definition: Repeating the same word or phrase at the beginning of successive sentences or clauses.

Example: Winston Churchill, June 1940: “We shall fight on the beaches, we shall fight on the landing grounds, we shall fight in the fields and in the streets…”

Use it: to build momentum and emphasis toward a climax. It is especially effective in speeches.

2. Epistrophe

Definition: Repeating the same word or phrase at the end of successive clauses.

Example: Abraham Lincoln’s Gettysburg Address: “…government of the people, by the people, for the people, shall not perish from the earth.”

Use it: to hammer home a single key idea.

3. Tricolon (the rule of three)

Definition: A series of three parallel words, phrases, or clauses.

Example: Julius Caesar (as reported by ancient writers): “Veni, vidi, vici” (“I came, I saw, I conquered”).

Use it: almost anywhere. Lists of three feel complete and balanced. Try it in thesis statements, speech previews, and conclusions: “faster, cheaper, and safer.”

4. Parallelism

Definition: Using the same grammatical structure for related ideas.

Example: John F. Kennedy’s inaugural address, 1961: “…we shall pay any price, bear any burden, meet any hardship, support any friend, oppose any foe…”

Use it: to show that ideas are equally important and to make sentences easier to follow. Faulty parallelism (“I like swimming, to run, and bikes”) sounds clumsy.

5. Epizeuxis

Definition: Repeating a word immediately, for emphasis.

Example: “Education, education, education,” a phrase used by Tony Blair to signal his government’s top priorities in 1996.

Use it: sparingly, for a single word you want the audience to feel.

Devices of Contrast and Balance

6. Antithesis

Definition: Placing contrasting ideas side by side in a balanced structure.

Example: Neil Armstrong, 1969: “That’s one small step for [a] man, one giant leap for mankind.”

Use it: to sharpen a choice or show the significance of an idea. Antithesis makes great closing lines.

7. Chiasmus

Definition: Reversing the order of words or ideas in the second half of a phrase (an A-B-B-A pattern).

Example: John F. Kennedy: “Ask not what your country can do for you; ask what you can do for your country.”

Use it: for a memorable final line. It’s difficult to write well, so draft several versions.

8. Juxtaposition

Definition: Placing two contrasting elements near each other to highlight their differences.

Example: The opening of Dickens’s A Tale of Two Cities: “It was the best of times, it was the worst of times…”

Use it: in introductions, to create tension your essay will explore.

9. Oxymoron

Definition: Combining two contradictory terms.

Examples: “deafening silence,” “bittersweet,” “open secret.”

Use it: to capture complex or paradoxical feelings in a few words.

Devices of Questioning and Address

10. Rhetorical question

Definition: A question asked for effect, not to get an answer.

Example: Sojourner Truth’s speech at the 1851 Women’s Convention in Akron, Ohio, is remembered for the refrain “Ain’t I a woman?” (The wording comes from later published accounts, which differ from one another.)

Use it: to prompt reflection or to introduce a point you’re about to answer. Avoid stacking several in a row.

11. Hypophora

Definition: Asking a question and then immediately answering it yourself.

Example: “So why do so many students struggle with essays? It isn’t a lack of ideas. It’s a lack of structure.”

Use it: to anticipate what your audience is wondering and guide them to your point. Very effective in speeches and essay introductions.

12. Apostrophe

Definition: Directly addressing someone absent, dead, or an abstract idea or object.

Example: John Donne: “Death, be not proud…”

Use it: mostly in poetry, eulogies, and dramatic moments in speeches.

Devices of Comparison and Imagery

13. Metaphor

Definition: Describing something as if it were something else, without “like” or “as.”

Example: Martin Luther King Jr., 1963: “…a lonely island of poverty in the midst of a vast ocean of material prosperity.”

Use it: to make abstract ideas concrete. Extended metaphors can carry through a whole speech.

14. Simile

Definition: A comparison using “like” or “as.”

Example: “Her words hit the room like cold water.”

Use it: to create vivid images. Avoid clichés (“as busy as a bee”).

15. Analogy

Definition: An extended comparison that explains an unfamiliar idea through a familiar one.

Example: “A firewall works like a security guard at the door of a building: it checks everyone coming in and turns away anyone not on the list.”

Use it: in informative essays and speeches, to explain complex processes. It’s one of the most useful tools for logos.

16. Allusion

Definition: An indirect reference to a well-known person, event, text, or work of art.

Example: Calling a difficult task “a Herculean effort” alludes to the labors of Hercules.

Use it: to add depth quickly, but only when your audience will recognize the reference.

Devices of Emphasis and Understatement

17. Hyperbole

Definition: Deliberate exaggeration for effect.

Example: “I’ve told you a million times.”

Use it: for humor or emotion in speeches and personal essays. Avoid it in academic arguments, where it can undermine credibility.

18. Litotes

Definition: Understatement by denying the opposite.

Example: “That was no small achievement.” / “She’s not unfamiliar with the subject.”

Use it: to sound measured and modest while still emphasizing a point.

19. Climax (auxesis)

Definition: Arranging words or ideas in order of increasing importance.

Example: “It’s a crime, it’s a scandal, it’s a betrayal of everything this school stands for.”

Use it: to build toward your most important point. Pairs naturally with tricolon and anaphora.

20. Asyndeton and polysyndeton

Definition: Asyndeton omits conjunctions (“I came, I saw, I conquered”), creating speed and urgency. Polysyndeton adds extra conjunctions (“and we laughed and we cried and we talked until dawn”), creating a sense of abundance or slowness.

Use it: to control rhythm. Asyndeton for punchy lists; polysyndeton for emotional, flowing passages.

How to Use Rhetorical Devices Well

Serve the message. Every device should make your point clearer, more memorable, or more persuasive. If it’s just there to sound impressive, cut it.
Don’t overdo it. One well-placed anaphora is powerful. Five in one paragraph is exhausting.
Save the best for key moments. Use your strongest devices in your opening, your thesis, transitions between major points, and especially your closing line.
Match the context. Speeches can handle more repetition and drama than academic essays. In formal writing, rely more on parallelism, antithesis, analogy, and careful rhetorical questions.
Read aloud. Rhetorical devices are rooted in sound. If it doesn’t sound good spoken, revise.

Analyzing Rhetoric in Texts

If you’re asked to write a rhetorical analysis, don’t just name devices. Explain their effect:

Weak: “Churchill uses anaphora.”
Strong: “Churchill’s repetition of ‘we shall fight’ creates a relentless rhythm that mirrors the determination he wants the British public to feel; each repetition sounds like another line of defense that refuses to give way.”

Identifying a device earns little credit. Explaining how and why it works is the real analysis.

Practice Exercise

Rewrite this plain sentence three times, using a different device each time (try anaphora, antithesis, and tricolon):

Reading helps students improve their vocabulary, their focus, and their empathy.

Sample answers:

Anaphora: “Reading builds vocabulary. Reading builds focus. Reading builds empathy.”
Antithesis: “Screens give students answers; books teach them to ask questions.”
Tricolon with climax: “Reading expands what students know, sharpens how they think, and deepens how they feel.”
