A
Accumulatio
noun
A
Etymology Latin: accumulation, a heaping up
A figure of thought in which the speaker summarizes and reinforces the main points of an argument in rapid succession at the end of a section or speech, creating the effect of overwhelming convergence. Often used at the peroration.
In Use
"You lied to the court, you deceived your partners, you defrauded your investors, and you betrayed your country — and now you ask for leniency."
Ad Hominem
noun / fallacy
A
Etymology Latin: to the person
A logical fallacy in which an argument is rejected not on its merits but because of something about the person making it — their character, affiliations, or perceived hypocrisy. A legitimate move when credibility is genuinely at issue; a fallacy when it substitutes for substantive engagement with the argument itself.
In Use
"We shouldn't listen to her argument about tax policy — she was convicted of tax evasion."
Allegory
noun
A
Etymology Greek allēgoria: speaking otherwise
An extended metaphor in which characters, events, and settings represent abstract ideas or moral qualities. Allegory sustains a second, figurative meaning throughout an entire narrative or discourse. Plato's Cave is allegory; Orwell's Animal Farm is allegory.
In Use
Spenser's The Faerie Queene uses characters named Holiness, Temperance, and Chastity to allegorize the virtues Elizabeth I was expected to embody.
Alliteration
noun
A
Etymology Medieval Latin alliteratio, from littera: letter
The repetition of the same initial consonant sound across a sequence of words in close proximity. A figure of sound that creates emphasis, musicality, and memorability. Distinct from assonance (repeated vowel sounds) and consonance (repeated consonant sounds in any position).
In Use
"Peter Piper picked a peck of pickled peppers." More rhetorically: Churchill's "blood, toil, tears, and sweat" — the tonal echo reinforcing the speech's martial gravity.
Allusion
noun
A
Etymology Latin allusio: a playing with, a reference
An indirect reference to a person, event, text, or cultural object that the speaker assumes the audience will recognize. Allusion compresses meaning by activating the audience's prior knowledge, lending the speaker's current point the weight of the alluded-to referent without requiring explicit elaboration.
In Use
"He met his Waterloo" alludes to Napoleon's final defeat, implying decisive and irreversible failure without naming Napoleon.
Amplification
noun
A
Etymology Latin amplificatio: an enlarging, a making great
The rhetorical process of expanding and intensifying a point by adding detail, repetition, accumulation, or additional perspectives. Amplification was one of the core operations of classical style, practiced through eight primary techniques in the Roman tradition: accumulation, division, reasoning by contraries, comparison, simile, example, authority, and description.
In Use
"This was not just a mistake. It was a catastrophic, irreversible, foreseeable, preventable catastrophe that will affect millions of people for generations."
Anaphora
noun
A
Etymology Greek anaphora: a carrying back
The repetition of the same word or phrase at the beginning of successive clauses, sentences, or lines. One of the most powerful and frequently used figures of rhetoric, anaphora creates rhythm, emphasis, and the effect of mounting conviction. The repetition makes each subsequent clause feel more inevitable and more powerful.
In Use
Martin Luther King Jr.'s "I have a dream" is the canonical modern example. Churchill: "We shall fight on the beaches, we shall fight on the landing grounds, we shall fight in the fields."
Antanaclasis
noun
A
Etymology Greek: a reflecting back, a bending back
A figure of repetition in which the same word is used multiple times but with different meanings each time. The shift in meaning creates emphasis through the contrast between the uses. Distinct from simple repetition because the meaning genuinely changes.
In Use
Benjamin Franklin: "Your argument is sound — all sound." The word 'sound' first means 'valid'; then means 'mere noise.' Also: "If you aren't fired with enthusiasm, you will be fired with enthusiasm."
Antimetabole
noun
A
Etymology Greek: a turning about
A figure of repetition in which the key words of a phrase are repeated in reverse grammatical order in the following clause, creating a chiastic structure with identical terms. Often used to make a distinction or reveal an irony through the reversal.
In Use
JFK: "Ask not what your country can do for you — ask what you can do for your country." Also: "We do not eat to live; we live to eat."
Antithesis
noun
A
Etymology Greek antithesis: opposition, setting against
The juxtaposition of contrasting ideas in parallel grammatical structures. Antithesis creates clarity by sharpening distinctions; it also creates the impression that the speaker has considered both sides of a question and has a definitive position. The balance of the structure creates persuasive force beyond the logical content of the contrast.
In Use
"It was the best of times, it was the worst of times." (Dickens). "Speech is silver; silence is golden." In argument: "Where they see chaos, we see opportunity."
Apophasis
noun
A
Etymology Greek: a denial, a saying off
A figure of thought in which the speaker raises a subject by claiming to pass over it or by denying that it will be mentioned. The denial accomplishes the introduction of the topic without the speaker appearing to introduce it. Also called praeteritio or paralipsis.
In Use
"I won't mention the fact that my opponent was arrested three times — this campaign is about the issues." The statement both denies and performs the mention.
Apostrophe
noun
A
Etymology Greek apostrophē: a turning away
A figure in which the speaker turns from the present audience to address an absent or imaginary person, place, abstract quality, or object directly. Creates emotional intensity by dramatizing the speaker's engagement with the addressed entity. Distinct from the grammatical apostrophe (punctuation mark).
In Use
Cicero: "O tempora! O mores!" (O what times! O what customs!) — addressing the abstraction of the times themselves. Also: a lawyer addressing 'Justice' rather than the jury.
Arete
noun
A
Etymology Greek aretē: excellence, virtue
In Aristotle's account of ethos, one of the three components of the speaker's credibility — specifically the speaker's moral character and virtue. A speaker perceived as honest, principled, and genuinely committed to good values persuades through the credibility that moral excellence confers. Distinct from phronesis (practical wisdom) and eunoia (goodwill).
In Use
A physician who acknowledges uncertainty and the limits of their knowledge demonstrates arete — the willingness to tell uncomfortable truth rather than perform false confidence.
Arrangement
noun
A
Etymology From Latin dispositio: a placing, an ordering
The second of the Five Canons of Rhetoric — the art of organizing a discourse's parts for maximum effectiveness. Classical arrangement prescribed a six-part structure: exordium, narration, partition, confirmation, refutation, and peroration. Modern rhetoric treats arrangement more flexibly but maintains that the order of information has significant persuasive consequences.
In Use
A lawyer who places the most damaging evidence before the jury has already partially lost the case, regardless of the argument's logical quality. Arrangement is argument.
Asyndeton
noun
A
Etymology Greek asyndeton: unconnected
The omission of conjunctions between coordinate words, phrases, or clauses. Creates a rapid, clipped, urgent effect — the absence of connective tissue makes the elements feel like a rush of simultaneous impressions. The opposite is polysyndeton (the addition of many conjunctions).
In Use
Caesar's "I came, I saw, I conquered" is the canonical example. The asyndeton makes the three acts feel instantaneous and absolute. Also: "He was brilliant, brutal, tireless, remorseless."
Auxesis
noun
A
Etymology Greek auxēsis: growth, increase
The arrangement of words, phrases, or clauses in ascending order of importance, weight, or emotional intensity — a climactic ordering that builds toward the most emphatic point. The opposite is meiosis (diminishment). Also used more broadly to mean amplification or exaggeration.
In Use
"A minor inconvenience, a serious setback, a catastrophe, an extinction-level event" — each term escalates the severity, making the final term land with maximum impact.
C
Catachresis
noun
C
Etymology Greek katachrēsis: misuse
The use of a word in a way that departs from its conventional meaning — either as deliberate stylistic transgression for effect, or as a strained, mixed, or forced metaphor. Some catachreses become so common they cease to register as unusual ("the leg of a table"); deliberate catachresis creates defamiliarization.
In Use
"To take arms against a sea of troubles" (Shakespeare, Hamlet) — one cannot take arms against a sea; the mixed metaphor is a deliberate catachresis that creates a sense of futile, confused struggle.
Chiasmus
noun
C
Etymology Greek letter chi (X) — referring to the cross-over structure
A figure of repetition in which the grammatical structure of a phrase or clause is reversed in the next phrase or clause, creating an ABBA pattern. Related to antimetabole but does not require the exact repetition of words — only the reversal of grammatical structure. Creates elegant, balanced, memorable formulations.
In Use
"Fair is foul, and foul is fair" (Shakespeare). "Do not live to eat, but eat to live" (Socrates). The X-pattern of the structure is felt even without repeating identical words.
Climax
noun
C
Etymology Greek klimax: ladder, staircase
In rhetoric, a figure in which a series of elements are arranged in ascending order of importance or emotional intensity, each step preparing for the next. Also used to describe the overall emotional and argumentative peak of a speech or composition. Related to auxesis and gradatio.
In Use
"First, they came for the socialists... then they came for the trade unionists... then they came for the Jews... and then they came for me." Each repetition escalates the stakes.
Consubstantiality
noun
C
Etymology Late Latin: sharing the same substance
Kenneth Burke's term for the condition of shared substance — interests, values, attitudes, sensations — that rhetoric creates between a speaker and an audience. Identification is the rhetorical process; consubstantiality is its product. Speakers and audiences become consubstantial when symbolic action successfully bridges their division.
In Use
When a political leader says "we are one people," and the audience believes it, a state of consubstantiality has been rhetorically produced — shared identity constituted through symbolic act rather than discovered as pre-existing fact.
Context Collapse
noun
C
Etymology Contemporary digital media theory (danah boyd)
The phenomenon in which a message composed for one audience is seen simultaneously by many other audiences for whom it was not calibrated. Particularly characteristic of social media, where a post addressed to friends may be read by employers, journalists, or hostile actors. Context collapse makes classical audience adaptation much harder and raises the stakes of rhetorical miscalculation.
In Use
A comedian's decade-old tweets — written for followers who shared their comic sensibility — go viral and are read by a general audience that lacks the contextual frame that made them funny, causing a crisis of ethos.
Copia
noun
C
Etymology Latin: abundance, plenty
Erasmus's term for linguistic abundance — the capacity to express the same idea in many different ways. Copia is not mere verbal prolixity but the trained mastery of the full range of rhetorical resources, enabling the selection of the most appropriate expression for any context. Erasmus demonstrated it by offering 147 variations of a single sentence.
In Use
The ability to express the same condolence in 40 different registers — formal, familiar, poetic, plain, emotional, restrained — represents copia. The educated writer selects the appropriate register rather than defaulting to a single formula.
D
Decorum
noun
D
Etymology Latin decorum: what is fitting, seemly
The rhetorical principle that style, tone, subject matter, and register must be appropriate to the occasion, audience, and purpose. Cicero and Quintilian treated decorum as the master principle of style: not the most ornate or the most plain, but whatever is fitting for this speaker, this audience, this moment. Violations of decorum — being too informal at a funeral, too formal at a party — are rhetorical failures regardless of logical content.
In Use
A commencement address that dwells on mortality and failure violates decorum for that occasion, regardless of the truth or profundity of its content.
Deliberative Rhetoric
noun
D
Etymology Latin deliberatio: weighing, consideration
One of Aristotle's three rhetorical genres — rhetoric addressed to a legislative or deliberative body, concerned with future action, and oriented toward the values of the beneficial and the harmful. The central question of deliberative rhetoric: what should we do? Associated with political speech, policy argument, and calls to action.
In Use
A senator arguing for a climate bill, a CEO presenting a strategic plan to the board, a parent arguing at a school board meeting — all practice deliberative rhetoric.
Delivery
noun
D
Etymology From Latin pronuntiatio / actio
The fifth of the Five Canons of Rhetoric — the vocal and physical performance of a discourse. Cicero called delivery "the dominant factor in oratory," and Demosthenes reportedly named it the most important, second most important, and third most important aspect of rhetoric. Encompasses voice (rate, pitch, volume, pause), body (gesture, posture, eye contact, movement), and facial expression.
In Use
The same sentence — "I did not say she stole the money" — communicates seven entirely different meanings depending on which word receives stress. Delivery determines meaning in ways that transcribed text cannot capture.
Dispositio
noun
D
Etymology Latin: arrangement, disposition
The Latin term for the second canon of rhetoric — arrangement. The art of ordering the parts of a discourse to achieve maximum persuasive effect. Classical dispositio prescribed the six-part oration: exordium, narratio, partitio, confirmatio, refutatio, peroratio. Each part has a specific rhetorical function, and departures from the template require strategic justification.
In Use
A lawyer who front-loads all their strongest evidence, rather than building to it, may be following good journalism practice (inverted pyramid) but poor dispositio — the strongest arguments often land harder when the audience has been prepared.
Docere
verb / noun
D
Etymology Latin: to teach
In Cicero's tripartite account of rhetorical purpose, docere is the function of teaching or instructing — engaging the audience's intellect and ensuring they understand the facts and arguments of the case. The other two functions are movere (moving the emotions) and delectare (giving pleasure). A complete rhetoric must achieve all three.
In Use
The expository section of a legal brief — setting out the facts, the applicable law, and the logical argument — performs docere. If the brief only informs without moving or pleasing, it is incomplete rhetoric.
E
Elenchus
noun
E
Etymology Greek elenkhos: refutation, cross-examination
The Socratic method of cross-examination — a form of inquiry that proceeds through questions designed to expose contradictions in the interlocutor's stated beliefs. The elenchus is rhetoric as epistemology: its goal is not the defeat of the interlocutor but the joint discovery of truth through the rigorous testing of claims.
In Use
Socrates asking Euthyphro to define piety, then showing that each definition he offers either contradicts a prior definition or relies on an unstated premise — leading Euthyphro (and the reader) to recognize that he does not actually know what piety is.
Elocutio
noun
E
Etymology Latin: a speaking out, expression
The Latin term for the third canon of rhetoric — style. The art of selecting and deploying language with clarity, correctness, appropriateness, and ornament. The most extensively theorized of the five canons, producing the vast classical and Renaissance literature on figures of speech, diction, rhythm, and register. The four primary virtues of style: correctness (Latinitas), clarity (perspicuitas), ornament (ornatus), and decorum (aptum).
In Use
The same argument can be expressed in a dozen different styles — and each style changes how the argument is received. Elocutio is the art of choosing and executing the style that best serves the argument with this audience in this moment.
Enthymeme
noun
E
Etymology Greek enthymema: thought, consideration
Aristotle's term for the primary instrument of rhetorical proof — a probabilistic syllogism that draws on shared audience knowledge, often leaving one premise unstated because the audience is assumed to already accept it. The rhetorical equivalent of the logical syllogism, but operating in the domain of the probable rather than the certain. The suppressed premise is what gives enthymemes their persuasive power: they engage the audience's own beliefs.
In Use
"She must be intelligent — she went to MIT." This suppresses the premise "MIT graduates are intelligent." The audience supplies the suppressed premise, making the argument feel more convincing than an explicitly stated syllogism.
Epideictic Rhetoric
noun
E
Etymology Greek epideixis: display, showing off
One of Aristotle's three rhetorical genres — rhetoric delivered on ceremonial occasions, concerned with praise or blame, and oriented toward the value of honor. Epideictic rhetoric is present-oriented and functions primarily to reinforce community values, define collective identity, and celebrate or condemn exemplary figures. Often underappreciated as "mere" ceremony; in fact, the rhetorical genre most responsible for shaping culture.
In Use
Eulogies, graduation speeches, award ceremonies, political conventions, national commemorations, product launches, and brand communications are all primarily epideictic.
Epiphora
noun
E
Etymology Greek: a bringing upon
Also called epistrophe — the repetition of the same word or phrase at the end of successive clauses or sentences. The mirror image of anaphora (which repeats at the beginning). Creates an emphatic, often incantatory effect; the repeated ending word accumulates emotional weight with each repetition.
In Use
"Government of the people, by the people, for the people" (Lincoln) — epiphora on "the people." Also: "When I was a child, I spoke as a child, I understood as a child, I thought as a child" (1 Corinthians 13).
Ethos
noun
E
Etymology Greek ēthos: character, custom, disposition
One of Aristotle's three modes of rhetorical proof — persuasion through the perceived character of the speaker. Aristotle identified three components: phronesis (practical wisdom — the speaker knows what they're talking about), arete (moral virtue — the speaker can be trusted), and eunoia (goodwill — the speaker has the audience's interests at heart). Ethos is not merely the speaker's reputation but is actively constructed within the discourse itself.
In Use
A doctor who acknowledges the uncertainty in a diagnosis demonstrates arete; one who shows intimate knowledge of the patient's specific circumstances demonstrates eunoia; one who accurately explains the relevant research demonstrates phronesis — all three components working together to create trust.
Eunoia
noun
E
Etymology Greek: goodwill, kindness of mind
In Aristotle's account of ethos, one of the three components of the speaker's credibility — specifically the speaker's demonstrated goodwill toward the audience. A speaker who appears to genuinely care about the audience's interests, rather than merely serving their own, is more credible. Eunoia is the component most often missed by technically competent speakers who fail to communicate genuine care.
In Use
A financial advisor who recommends a product that is in the client's interest rather than the advisor's commission demonstrates eunoia — and builds the client loyalty that serves long-term self-interest anyway.
Exemplum
noun
E
Etymology Latin: example, model
A historical or fictional example used as evidence or illustration in an argument. Aristotle identified the example (paradeigma) as one of the two primary modes of rhetorical proof (alongside the enthymeme), functioning as the inductive counterpart to the deductive enthymeme. A single powerful exemplum can be more persuasive than many abstract claims.
In Use
A preacher citing the story of the Prodigal Son as evidence that God's mercy extends even to the most wayward. A trial lawyer citing a similar prior case as precedent. Both are deploying exempla as rhetorical proof.
Exigence
noun
E
Etymology From Latin exigentia: need, demand
Lloyd Bitzer's term for the urgent problem or imperfection that calls a rhetorical discourse into being. The exigence is not merely the occasion for speech but the specific rhetorical need — the situation that requires a particular kind of communicative response. An imperfection that cannot be addressed through human action is not a rhetorical exigence; a genuine exigence is one that rhetoric can modify.
In Use
Lincoln's exigence for the Gettysburg Address was not simply the cemetery dedication ceremony but the urgent need to redefine the meaning of the Civil War — to transform it from a war about union into a war about equality.
Exordium
noun
E
Etymology Latin: a beginning, the warp of a web
The opening section of a classical oration — its function is to secure the audience's attention (attentum parare), goodwill (benevolum parare), and receptivity (docilem parare). The exordium must make the audience want to listen and prepare them to receive the argument favorably. The equivalent in modern writing is the hook or lead.
In Use
A lawyer who opens with the story of the victim — making the jury feel the human stakes before hearing the legal argument — is building an effective exordium: the facts will be more persuasive because the audience already cares.
F
Fallacy
noun
F
Etymology Latin fallacia: a trick, deception
An error in reasoning that makes an argument invalid, weak, or misleading — either through formal violation of logical rules or through informal errors in the use of evidence, language, or appeals. Formal fallacies violate the rules of valid inference; informal fallacies cover a broad range of errors in content, context, and rhetorical exploitation of cognitive biases.
In Use
Ad hominem, straw man, false dichotomy, appeal to authority, hasty generalization, post hoc ergo propter hoc, and slippery slope are among the most common informal fallacies. Recognizing them is a core skill of rhetorical literacy.
Figures of Speech
noun
F
Etymology Latin figurae elocutionis
Departures from ordinary, expected language use that create specific rhetorical effects. Rhetoricians distinguished tropes (figures involving a change in the meaning of words, like metaphor and metonymy) from schemes (figures involving a change in the arrangement of words, like anaphora and chiasmus). The classical tradition catalogued hundreds of figures; modern practice focuses on the most commonly useful.
In Use
Anaphora, chiasmus, antithesis, hyperbole, metaphor, simile, alliteration, and tricolon are among the most important figures for practicing rhetoricians.
Five Canons of Rhetoric
noun
F
Etymology Systematized by Cicero in De Inventione and Ad Herennium
The classical framework organizing the five dimensions of effective communication: Inventio (invention — discovering and generating arguments), Dispositio (arrangement — organizing material), Elocutio (style — selecting and deploying language), Memoria (memory — internalizing discourse), and Pronuntiatio (delivery — vocal and physical performance). The most enduring pedagogical framework in rhetorical education.
In Use
Writing a speech involves all five canons: deciding what to say (inventio), structuring it effectively (dispositio), crafting the language (elocutio), rehearsing until fluent (memoria), and performing it compellingly (pronuntiatio).
Forensic Rhetoric
noun
F
Etymology Latin forum: public space, marketplace
One of Aristotle's three rhetorical genres — rhetoric addressed to a judicial audience, concerned with past actions, and oriented toward the values of justice and injustice. The central question of forensic rhetoric: what happened, and was it just? The genre of the law court, the investigation, and the historical judgment.
In Use
Trial advocacy, legal briefs, investigative journalism, historical assessments of responsibility, and criminal prosecutions are all exercises in forensic rhetoric.
Frame
noun
F
Etymology Old English: to profit, be helpful; modern cognitive science sense from Erving Goffman and George Lakoff
A cognitive structure that organizes how we interpret a domain of experience — what counts as a problem, who the relevant actors are, what causal relationships obtain, and what solutions are conceivable. Frames are activated by specific words, images, and narratives; once active, they shape interpretation of all subsequent information. Competing political arguments are often competing frames rather than competing facts.
In Use
"Tax relief" and "civic investment" are competing frames for the same government policy. The frame activated by the language determines what emotions, values, and arguments become relevant to the discussion.
I
Identification
noun
I
Etymology Kenneth Burke's term, from Latin identificare: to make identical
Kenneth Burke's replacement for 'persuasion' as rhetoric's master term — the process by which a speaker invites an audience to see themselves as sharing substance (interests, values, attitudes, sensations) with the speaker or the speaker's cause. Identification is necessary precisely because people are irreducibly separate (divided); rhetoric bridges this division by creating provisional consubstantiality. The process operates through language, imagery, gesture, and every other semiotic resource.
In Use
"I grew up in a town just like yours." "We share the same values." "This threat faces all of us." Each is an act of identification — an invitation to discover shared substance.
Inventio
noun
I
Etymology Latin inventio: discovery, finding
The first of the Five Canons of Rhetoric — the art of discovering and generating arguments, evidence, and material appropriate to the rhetorical situation. Inventio is not invention in the modern sense (creating from nothing) but discovery: finding the available arguments through systematic exploration of topics. The classical topoi were the primary tool of inventio.
In Use
Before writing a brief, a lawyer engaging in inventio asks: What are all the arguments for my client's position? What arguments will the opponent make? What facts, precedents, analogies, and principles are relevant to this case? Systematic inventio prevents the error of arguing only the obvious.
Irony
noun
I
Etymology Greek eirōneia: simulated ignorance
The use of language to mean something different from — typically opposite to — its literal meaning, relying on the audience's ability to detect the gap between stated and intended meaning. Verbal irony is a figure of speech; dramatic irony (in narrative) involves the audience knowing something a character does not. Rhetorical irony can be a powerful tool for critique, humor, and indirection.
In Use
"Oh yes, that went brilliantly" (about a disaster). Swift's "A Modest Proposal" — proposing to eat Irish babies as a solution to poverty — is sustained rhetorical irony: the literal proposal is monstrous; the critique of English policy toward Ireland is the actual argument.
Isocolon
noun
I
Etymology Greek: equal members
A figure of parallelism in which two or more clauses or phrases have the same length (number of syllables or words) and the same grammatical structure. Creates a sense of perfect balance, equality, and formal elegance. Related to parallelism but specifically concerned with equal length as well as parallel structure.
In Use
Caesar: "I came, I saw, I conquered" — three verbs, identical structure, identical rhythm. "Veni, vidi, vici" in Latin has exact metrical equality. More loosely: "Work hard, play hard, live fully."
M
Memoria
noun
M
Etymology Latin memoria: memory
The fourth of the Five Canons of Rhetoric — the internalization of a discourse for performance. In the age of written communication, memoria is often treated as the least relevant canon; in antiquity it was considered essential, and the classical memory systems — placing vivid images in imagined architectural spaces — were among the most sophisticated cognitive technologies of the ancient world.
In Use
Cicero reportedly had memorized thousands of arguments, examples, and passages from the Greek and Latin literary tradition, enabling him to deploy appropriate material spontaneously in oral argument. The modern equivalent is deep internalization of material so that it feels spontaneous rather than recited.
Metaphor
noun
M
Etymology Greek metaphora: a carrying over, transfer
The most fundamental trope — the description of one thing in terms of another. For Aristotle, metaphor was the mark of genius, requiring the perception of similarity in dissimilar things. For Lakoff and Johnson, conceptual metaphor is not a literary device but the cognitive infrastructure through which we understand abstract experience. Metaphor frames, reveals, and conceals — every metaphor highlights certain aspects of its subject and backgrounds others.
In Use
"Argument is war" (Lakoff) — we attack positions, defend our claims, demolish arguments, and score points. The military metaphor highlights the adversarial dimension of argument while backgrounding its collaborative, truth-seeking dimension.
Metonymy
noun
M
Etymology Greek metōnymia: change of name
A trope in which one thing is referred to by the name of something closely associated with it — the container for the contents, the producer for the product, the institution for its members. Metonymy works through contiguity (things that go together) rather than similarity (things that resemble each other, as in metaphor). Much of our ordinary language is metonymic.
In Use
"The White House announced today" (the institution for its occupants). "Washington is divided" (the city for its politicians). "Have you read Proust?" (the author for his works). "The kettle is boiling."
Movere
verb / noun
M
Etymology Latin: to move
In Cicero's account of rhetorical purpose, movere is the function of moving the audience emotionally — engaging the passions in ways that motivate action and deepen conviction. The other two functions are docere (teaching) and delectare (pleasing). Cicero considered movere the most powerful rhetorical function — and the most difficult to achieve honestly.
In Use
A lawyer's closing argument that makes the jury feel the victim's suffering is performing movere. Without it, the most logically complete case may fail to produce a verdict.
P
Paralipsis
noun
P
Etymology Greek: a passing over
A figure in which the speaker mentions something by claiming to omit it — emphasizing a point by pretending to pass over it. Related to apophasis and praeteritio. The rhetorical effect: the content is communicated without the speaker appearing to choose to communicate it, lending it the appearance of reluctant truth rather than deliberate assertion.
In Use
"I won't even mention the fact that he was fired from his last three jobs." The mention in the denial achieves the rhetorical goal while maintaining the speaker's appearance of restraint.
Parallelism
noun
P
Etymology Greek parallelos: alongside one another
The use of similar grammatical structures for similar ideas — coordinating equal ideas in equal forms. Parallelism creates clarity (by signaling that the parallel elements are equal in status or type), elegance (through formal balance), and rhythm (through the repetition of structure). Failures of parallelism signal careless thinking as well as careless writing.
In Use
"I came to study, to learn, and to grow" — three infinitives in parallel. Compare: "I came to study, learning, and growth" — the violation of parallel structure signals that the three items are not truly coordinate.
Parrhesia
noun
P
Etymology Greek: frankness of speech, speaking everything
Frank, fearless speech that tells the truth to power at personal risk. Parrhesia is a virtue of rhetorical character — the willingness to say what needs to be said to an audience that may not want to hear it, because truth and goodwill demand it. Foucault devoted his final lectures to parrhesia as a practice of self-constitution and political resistance.
In Use
A physician who tells a patient their lifestyle is killing them, at the risk of losing them as a patient. A general who tells the Commander-in-Chief the war cannot be won. An employee who tells the CEO the strategy is wrong.
Pathos
noun
P
Etymology Greek pathos: experience, suffering, emotion
One of Aristotle's three modes of rhetorical proof — persuasion by putting the audience in the right emotional state. Aristotle devoted an entire book of the Rhetoric to analyzing emotions systematically: what produces each emotion, what its opposite is, and what audiences are most susceptible to each. Emotional appeals are not irrational departures from argument but legitimate means of engaging the full human capacity for evaluation.
In Use
A lawyer who presents photographs of a crime scene before presenting the legal argument is using pathos not to bypass rational evaluation but to ensure that the emotional reality of the harm is present to the jury during their deliberation.
Peroration
noun
P
Etymology Latin peroratio: a speaking at length, a conclusion
The concluding section of a classical oration — its function is to summarize the argument (recapitulatio), amplify the emotional appeal (amplificatio), and move the audience to a specific response (commiseratio or indignatio). The peroration should close the speech on its highest emotional and argumentative note; it is what the audience remembers.
In Use
Lincoln's "with malice toward none" closing at the Second Inaugural is a masterpiece of peroration: it summarizes the war's meaning, amplifies the appeal to national reconciliation, and issues a call to action — all in three sentences.
Persona
noun
P
Etymology Latin: mask (worn by actors in Roman theater)
The public identity or character that a speaker or writer constructs for a particular rhetorical context — the 'I' of the discourse, which may or may not correspond closely to the author's private self. Every rhetorical act involves persona construction: the choice of how to present oneself, which aspects of identity to foreground, and which voice to adopt.
In Use
A politician's "plain-speaking outsider" persona; a brand's "friendly expert" persona; a writer's carefully crafted authorial voice. The construction of persona is itself a rhetorical act, and audiences often respond as much to persona as to argument.
Phronesis
noun
P
Etymology Greek phrónēsis: practical wisdom, prudence
In Aristotle's account of ethos, one of the three components of the speaker's credibility — specifically the speaker's practical wisdom or good judgment. A speaker who demonstrates sound understanding of the subject, accurate knowledge of the facts, and good judgment about what to do in complex situations persuades through the credibility that competence confers.
In Use
A general who accurately assesses the military situation and recommends a strategy that proves correct demonstrates phronesis. The demonstrated accuracy of past judgments is the most powerful form of phronesis-based ethos.
Polyptoton
noun
P
Etymology Greek: using many cases (of a word)
A figure of repetition in which the same word appears in different grammatical forms (different cases, persons, tenses, or parts of speech). Creates emphasis through variation — the changing form signals that the concept is being examined from multiple angles.
In Use
"We shall not fail. We shall not falter. Failure is not an option." — The noun and verb forms of 'fail/failure' create polyptoton. Also: "With eager feeding food doth choke the feeder" (Shakespeare).
Polysyndeton
noun
P
Etymology Greek: much bound together
The use of many conjunctions between coordinate elements — the opposite of asyndeton. Where asyndeton creates a rapid, clipped effect, polysyndeton creates a slow, deliberate, often solemn or exhaustive effect. Each element is given equal weight and full pause; nothing is rushed past.
In Use
Genesis: "And God saw the light, and it was good. And God divided the light from the darkness. And God called the light Day, and the darkness he called Night." The accumulated 'and's create a stately, inexorable rhythm.
Praeteritio
noun
P
Etymology Latin: a passing by
A figure in which the speaker declares their intention not to discuss something — and in so doing, discusses it. Identical in function to apophasis and paralipsis. The figure allows the speaker to introduce a damaging or controversial point while maintaining the rhetorical position of having chosen not to raise it.
In Use
"I shall not rehearse here all the evidence of my opponent's conflicts of interest — that is not the kind of campaign I intend to run." The conflicts of interest have been mentioned; the speaker has also claimed moral high ground.
Prolepsis
noun
P
Etymology Greek: a taking beforehand
Anticipating and addressing an objection before the audience raises it. A powerful ethos-building technique: it demonstrates that the speaker has considered opposing views, and it frames the objection on the speaker's terms. Also used in narrative to refer to anticipating future events (a flashforward).
In Use
"Before you object that this plan is too costly, let me show you why its long-term savings make it the fiscally responsible choice." The objection has been named, owned, and answered before it could be used against the speaker.
Pronuntiatio
noun
P
Etymology Latin: a pronouncing, delivery
The Latin term for the fifth canon of rhetoric — delivery. Also called actio. Encompasses the full range of vocal and physical presentation: voice quality, rate, volume, pitch variation, articulation, pause, facial expression, gesture, posture, and movement. Classical rhetoricians considered it the most powerful component of actual persuasion in practice.
In Use
The same sentence delivered in a whisper of intimacy versus a shout of indignation produces entirely different rhetorical effects. Demosthenes was reportedly asked what the most important quality in an orator was. His answer: 'Delivery, delivery, delivery.'
Prosopopoeia
noun
P
Etymology Greek: face-making, personification
A figure in which an absent or imaginary person is represented as speaking or acting — sometimes called personification when abstract qualities are given human voice. Related to apostrophe (addressing an absent entity) but specifically involves giving that entity a voice and persona. A powerful device for imagining alternative perspectives.
In Use
Cicero's Pro Caelio, in which he imagines the voice of the ancient Appius Claudius speaking from beyond the grave to rebuke Clodia. A lawyer saying: "If the victim could speak today, she would say..."
R
Refutatio
noun
R
Etymology Latin: a beating back, refutation
The fifth part of the classical oration — the systematic answering of the opponent's arguments. A well-constructed refutatio anticipates the strongest objections, states them fairly (sometimes more strongly than the opponent did), and then demonstrates why they fail. Weak refutation that attacks only easy targets (the straw man fallacy) damages the speaker's ethos.
In Use
A lawyer who spends three minutes of their closing argument on the three most compelling arguments the opposing counsel made — and genuinely answers each — demonstrates both intellectual honesty and argumentative confidence.
Rhetor
noun
R
Etymology Greek rhētōr: public speaker, orator
The speaker or writer who produces a rhetorical discourse. In modern rhetorical theory, the rhetor is not necessarily a single human individual: institutions, organizations, social movements, and even algorithms can function as rhetors when they produce systematic communicative interventions. The rhetor is one element of the rhetorical situation alongside audience, exigence, and constraints.
In Use
The rhetor of a presidential address is technically the president, but the actual discourse is produced by speechwriters, communications staff, and institutional processes. In social media, platform algorithms are rhetors that shape what arguments billions of people encounter.
Rhetorical Question
noun
R
Etymology Greek erotēma
A question asked for effect rather than to elicit information — one whose answer is assumed, obvious, or beside the point. Rhetorical questions invite the audience to supply the answer themselves, creating the experience of independent reasoning that makes the conclusion feel more genuinely held. They can express indignation, generate agreement, or frame an issue.
In Use
"Are we going to let this continue?" (Inviting the answer: No.) "Is this the best we can do?" (Inviting the answer: No.) "Who among us has not felt this way?" (Inviting agreement.)
Rhetorical Situation
noun
R
Etymology Term coined by Lloyd Bitzer, 1968
Lloyd Bitzer's model of the context within which rhetorical discourse is produced and received. The rhetorical situation comprises three elements: the exigence (the urgent problem requiring a response), the audience (those who can be influenced to modify the exigence), and the constraints (factors that limit the available rhetorical moves). Every effective discourse responds to its specific rhetorical situation.
In Use
Lincoln's exigence at Gettysburg was the need to redefine the meaning of the Civil War; his audience was the mourners and, through publication, the nation; his constraints included the specific genre of the cemetery dedication and the expectations of the occasion.
S
Sententia
noun
S
Etymology Latin: opinion, feeling, meaning
A pithy, memorable expression of a general truth — a maxim or aphorism used in an argument to give weight and authority to a specific claim. The sententia connects the particular case to a universal principle, lending the principle's authority to the argument. Often appears at the conclusion of a section as a pointed summary.
In Use
"The more things change, the more they stay the same." "Power tends to corrupt." "We do not inherit the earth from our ancestors; we borrow it from our children." Each is a sententia — a general truth that can be deployed in specific arguments.
Simile
noun
S
Etymology Latin similis: like, resembling
An explicit comparison between two different things using 'like' or 'as.' Distinct from metaphor in that the comparison is stated rather than implied — the tenor and vehicle remain distinct rather than fusing. Similes can be analyzed into their stated and unstated components: the stated comparison activates a set of associations that then transfer to the subject being described.
In Use
"Her voice was like honey poured over gravel." "The negotiations were as productive as rearranging deck chairs on the Titanic." The Titanic simile imports the entire narrative of futility and impending disaster into the characterization of the negotiations.
Stasis Theory
noun
S
Etymology Greek stasis: standing, position, point of rest
A classical method for identifying the precise point of dispute in any controversy — the question on which the argument 'stands.' Developed by Hermagoras of Temnos and elaborated by Cicero and Quintilian, stasis theory identifies four fundamental types of dispute: fact (did it happen?), definition (what kind of thing is it?), quality (what is its moral character?), and procedure (is this the right forum?). Identifying the correct stasis prevents arguing at the wrong level.
In Use
A criminal trial may involve all four stases simultaneously: Fact (did the defendant commit the act?), Definition (was it assault or self-defense?), Quality (if assault, was it justified?), Procedure (is this court the proper venue?). The defense wins by attacking the strongest stasis.
Style
noun
S
Etymology Latin stilus: a writing instrument; later, a manner of writing
The third of the Five Canons of Rhetoric — the selection and deployment of language to express thought with clarity, correctness, appropriateness, and ornament. Style is not a superficial coating applied to pre-existing content; it is constitutive of meaning. The how of expression is inseparable from the what. Classical rhetoricians distinguished three primary styles: grand (elevated, emotional), middle (moderate, elegant), and plain (simple, clear).
In Use
The same information delivered in plain style ("the company lost money"), middle style ("the quarter's results fell short of expectations"), and grand style ("we stand at the precipice of financial reckoning") produces different understandings and different emotional responses to the same underlying fact.
Syllepsis
noun
S
Etymology Greek: a taking together
A figure in which a single word (often a verb) governs two or more words but applies to each in a different sense. Related to zeugma but specifically involves the grammatical or semantic mismatch between the shared word and its multiple objects. When it works, the effect is witty or surprising; when it doesn't, it reads as careless.
In Use
Dickens: "She went home in a flood of tears and a sedan chair." The word 'flood' applies literally to tears and absurdly to a sedan chair; the mismatch creates wry comic effect. Also: "He took his leave and several hundred dollars."
Syllogism
noun
S
Etymology Greek syllogismos: reasoning, inference
A form of deductive reasoning in which a conclusion follows necessarily from two premises. The classical form: major premise (all X are Y) + minor premise (Z is X) = conclusion (Z is Y). In rhetoric, the syllogism is the formal model against which the enthymeme (the probabilistic rhetorical syllogism) is contrasted — rhetoric deals in probabilities, not certainties, so rhetorical argument is enthymematic rather than syllogistic.
In Use
All men are mortal. Socrates is a man. Therefore, Socrates is mortal. In practice, rhetorical arguments rarely have the certainty of valid syllogisms — they work with probable premises and probable inferences.
Symploce
noun
S
Etymology Greek: an interweaving
A figure that combines anaphora (repetition at the beginning) with epiphora (repetition at the end) — the same phrase or word appears at both the start and the end of successive clauses. Creates an enclosed, insistent structure that feels both cumulative and circular.
In Use
"We will not fail them. We will not forget them. We will not abandon them." — Anaphora on 'we will not'; the parallelism is complete. More perfectly: "If you worked hard, you succeeded hard; if you played hard, you lived hard."
Synecdoche
noun
S
Etymology Greek: a taking together, an understanding
A trope in which a part represents the whole, or the whole represents a part. Related to metonymy (which works through contiguity) but specifically involves part-whole relationships. Synecdoche is one of the most pervasive figures in ordinary language — we use it without noticing.
In Use
"All hands on deck" (hands = sailors). "Give us this day our daily bread" (bread = all food, all sustenance). "The Pentagon announced" (the building = the military establishment). "Nice wheels" (wheels = the entire vehicle).
T
Terministic Screens
noun
T
Etymology Kenneth Burke, A Grammar of Motives (1945)
Kenneth Burke's concept that every terminology — every set of terms used to describe reality — simultaneously directs attention toward certain features and away from others. Like photographic filters, different terminologies produce different 'pictures' of the same reality. The choice of terms is never neutral: it is always a selective emphasis that serves some purposes and obscures others.
In Use
Describing an economic system as 'the free market' versus 'capitalism' versus 'the neoliberal order' are three different terministic screens applied to the same phenomenon — each highlighting different features and implying different evaluations and solutions.
Topoi
noun
T
Etymology Greek topos: place (singular); topoi: places (plural)
The 'places' or categories of argument in classical rhetoric — systematic locations where arguments can be found through inventio. Common topoi include: definition, comparison, relationship (cause and effect), circumstances (possible/impossible), and testimony (authority). Special topoi are arguments specific to particular disciplines. The topoi are tools for ensuring that all available arguments have been considered before a discourse is constructed.
In Use
Using the topos of comparison: "If we invest in early education, we prevent later crime — this has been proven in dozens of municipalities." The comparison topos asks: where has a similar approach been tried, and what happened?
Tricolon
noun
T
Etymology Greek: three members
A figure of three parallel elements — words, phrases, or clauses — presented in a series. One of the most powerful and ubiquitous structures in rhetoric and literature, the tricolon creates a sense of completeness and inevitability. Three has an aesthetic and cognitive privilege: two elements feel unresolved; four feels excessive; three feels exactly sufficient.
In Use
"Life, liberty, and the pursuit of happiness." "Liberté, égalité, fraternité." "Veni, vidi, vici." "Blood, toil, tears, and sweat." (Churchill deliberately extended the classic tricolon to disrupt the expected resolution, creating additional weight.)
Trope
noun
T
Etymology Greek tropos: a turn, turning
A figure of speech involving a 'turn' or change in the meaning of words — distinct from a scheme (which changes word arrangement). The primary tropes are metaphor, metonymy, synecdoche, and irony. Tropes work by transporting meaning from one domain to another; the transportation illuminates, distorts, and frames simultaneously. Deconstruction theory treats trope as fundamental to all language.
In Use
Metaphor ('the world is a stage'), metonymy ('the White House decided'), synecdoche ('all hands'), and irony ('what a wonderful performance') — each involves a turn in meaning that carries the vehicle's associations to the tenor.
Tu Quoque
noun / fallacy
T
Etymology Latin: you too, you also
A logical fallacy in which an argument is rejected on the grounds that the person making it is guilty of the same error they are criticizing. "You can't tell me not to smoke — you smoke yourself." The fallacy: the argument's validity is independent of whether the speaker adheres to it. (Though the speaker's credibility may legitimately be affected.)
In Use
"You argue we should reduce emissions, but you fly internationally multiple times a year." This may affect the speaker's ethos (hypocrisy) but does not refute the argument about emissions reduction.
