Rhetoric: how persuasion works
English · Key Stage 3 · The School
The devices worth knowing
A rhetorical question asks without wanting an answer. A triad lists three things because three sounds complete. Repetition drives a phrase home. Direct address makes “you” responsible. A statistic borrows authority. Emotive language chooses the loaded word — “slaughtered” rather than “killed”. Six devices covers most of what any speech is doing.
Naming is not analysing
“The writer uses a rhetorical question” earns almost nothing. What did it do? A rhetorical question makes the reader supply the answer themselves, so they end up agreeing with a point the writer never had to prove. Say what the device does to the reader, and the mark follows.
Why three is the magic number
Two items sound like a list that got cut short; four begins to drag. Three sounds finished, which is why speeches are full of triads and why they are almost invisible until you look for them. The rhythm carries a sense of completeness that the argument may not have earned.
Persuasion is a technique, so it can be turned on you
The same devices sell a charity appeal and an unpleasant political argument. Learning them is not only about writing better; it is about noticing when a piece of writing is working on you. A statistic with no source, a triad with no evidence, a loaded verb — these are worth spotting in things you did not choose to read.
Every device serves one of three appeals, and naming the appeal is what turns description into analysis. ETHOS is trust me: credentials, shared values, plain speaking. PATHOS is feel this: anecdote, emotive word choice, the single named victim. LOGOS is the evidence says so: statistics, cause and effect, concession then rebuttal. A rhetorical question is not simply a rhetorical question — it is usually pathos, handing the reader the answer so it feels like their own.
