Owing to its origin in ancient Greece and Rome, English rhetorical theory frequently employs Greek and Latin words as terms of art. This page explains commonly used rhetorical terms in alphabetical order. The brief definitions here are intended to serve as a quick reference rather than an in-depth discussion.

Rhetoric is the art of persuasion. It is one of the three ancient arts of discourse (trivium) along with grammar and logic/dialectic. As an academic discipline within the humanities, rhetoric aims to study the techniques that speakers or writers use to inform, persuade, and motivate their audiences. Rhetoric also provides heuristics for understanding, discovering, and developing arguments for particular situations.
A sophist was a teacher in ancient Greece in the fifth and fourth centuries BCE. Sophists specialized in one or more subject areas, such as philosophy, rhetoric, music, athletics and mathematics. They taught arete, "virtue" or "excellence", predominantly to young statesmen and nobility.
Metonymy is a figure of speech in which a concept is referred to by the name of something closely associated with that thing or concept.
A figure of speech or rhetorical figure is a word or phrase that intentionally deviates from straightforward language use or literal meaning to produce a rhetorical or intensified effect. In the distinction between literal and figurative language, figures of speech constitute the latter. Figures of speech are traditionally classified into schemes, which vary the ordinary sequence of words, and tropes, where words carry a meaning other than what they ordinarily signify.
Antithesis is used in writing or speech either as a proposition that contrasts with or reverses some previously mentioned proposition, or when two opposites are introduced together for contrasting effect.
In rhetoric, litotes, also known classically as antenantiosis or moderatour, is a figure of speech and form of irony in which understatement is used to emphasize a point by stating a negative to further affirm a positive, often incorporating double negatives for effect. Litotes is a form of understatement, which can be in the form of meiosis, and is always deliberate with the intention of emphasis. However, the interpretation of negation may depend on context, including cultural context. In speech, litotes may also depend on intonation and emphasis; for example, the phrase "not bad" can be intonated differently so as to mean either "mediocre" or "excellent". Along the same lines, litotes can be used, to euphemistically provide emphasis by diminishing the harshness of an observation; "He isn't the cleanest person I know" could be used as a means of indicating that someone is a messy person.
Hyperbole is the use of exaggeration as a rhetorical device or figure of speech. In rhetoric, it is also sometimes known as auxesis. In poetry and oratory, it emphasizes, evokes strong feelings, and creates strong impressions. As a figure of speech, it is usually not meant to be taken literally.
In rhetoric, a rhetorical device, persuasive device, or stylistic device is a technique that an author or speaker uses to convey to the listener or reader a meaning with the goal of persuading them towards considering a topic from a perspective, using language designed to encourage or provoke an emotional display of a given perspective or action. They seek to make a position or argument more compelling than it would otherwise be.
In rhetoric, zeugma and syllepsis are figures of speech in which a single phrase or word joins different parts of a sentence.
In literature and writing, stylistic devices are a variety of techniques used to give an auxiliary meaning, idea, or feeling.
Pathos appeals to the emotions and ideals of the audience and elicits feelings that already reside in them. Pathos is a term used most often in rhetoric, as well as in literature, film and other narrative art.
Inventio, one of the five canons of rhetoric, is the method used for the discovery of arguments in Western rhetoric and comes from the Latin word, meaning "invention" or "discovery". Inventio is the central, indispensable canon of rhetoric, and traditionally means a systematic search for arguments.
Dispositio is the system used for the organization of arguments in the context of Western classical rhetoric. The word is Latin, and can be translated as "organization" or "arrangement".
The Rhetorica ad Herennium is the oldest surviving Latin book on rhetoric, dating from the late 80s BC. It was formerly attributed to Cicero or Cornificius, but is in fact of unknown authorship, sometimes ascribed to an unnamed doctor.
A literary trope is the use of figurative language, via word, phrase or an image, for artistic effect such as using a figure of speech. Keith and Lundburg describe a trope as "a substitution of a word or phrase by a less literal word or phrase". The word trope has also undergone a semantic change and now also describes commonly recurring or overused literary and rhetorical devices, motifs or clichés in creative works. Literary tropes span almost every category of writing, such as poetry, film, plays, and video games.
In rhetoric, a scheme is a type of figure of speech that relies on the structure of the sentence, unlike the trope, which plays with the meanings of words.
In classical rhetoric, figures of speech are classified as one of the four fundamental rhetorical operations or quadripartita ratio: addition (adiectio), omission (detractio), permutation (immutatio) and transposition (transmutatio).
In literary criticism and rhetoric, a tautology is a statement that repeats an idea, using near-synonymous morphemes, words or phrases, effectively "saying the same thing twice". Tautology and pleonasm are not consistently differentiated in literature. Like pleonasm, tautology is often considered a fault of style when unintentional. Intentional repetition may emphasize a thought or help the listener or reader understand a point. Sometimes logical tautologies like "Boys will be boys" are conflated with language tautologies, but a language tautology is not inherently true, while a logical tautology always is.
In rhetoric, parallel syntax is a rhetorical device that consists of repetition among adjacent sentences or clauses. The repeated sentences or clauses provide emphasis to a central theme or idea the author is trying to convey. Parallelism is the mark of a mature language speaker.
The Elements of Eloquence: How to Turn the Perfect English Phrase is a non-fiction book by Mark Forsyth published in 2013. The book explains classical rhetoric, dedicating each chapter to a rhetorical figure with examples of its use, particularly in the works of William Shakespeare. Forsyth argues the power of Shakespeare's language was a result of studying formal rhetoric, and highlights their use through Shakespeare's development.
