Understanding Rhetorical Devices in IB English A
In IB English A: Language & Literature, students analyze non-fiction texts such as speeches, essays, advertisements, and opinion pieces. These texts often use rhetorical devices — persuasive techniques designed to influence or move an audience.
Mastering rhetorical analysis is crucial for Paper 1 commentaries, Individual Orals (IOs), and Higher Level Essays (HLEs). It allows students to demonstrate how language shapes power, persuasion, and perspective, a key aspect of IB assessment criteria.
What Are Rhetorical Devices?
Rhetorical devices are deliberate language techniques authors use to persuade, emphasize, or evoke emotion. They can appear through word choice (diction), structure, or figurative language.
Example:
In Martin Luther King Jr.’s “I Have a Dream” speech, repetition of the phrase “I have a dream” emphasizes unity, hope, and moral conviction — a rhetorical strategy that stirs emotional response (pathos) while reinforcing the message’s rhythm.
The Three Classical Appeals | Ethos, Pathos, Logos
The foundation of rhetorical analysis in IB English comes from Aristotle’s rhetorical triangle, which highlights three modes of persuasion:
1. Ethos – Credibility and Authority
Appeals to ethics and the speaker’s credibility.
Example: “As a doctor with 20 years of experience, I can assure you this treatment is safe.”In IB analysis, note how the writer builds trust or authority through expertise, tone, or personal reputation.
