Terms AP English Language and Composition: 60 Key Terms

Earning a high score on the AP English Language and Composition exam depends less on memorizing long lists and more on recognizing how writers make choices—and being able to name those choices precisely. That is why learning the core terms AP English Language and Composition covers is so useful: they give you a shared vocabulary for analyzing rhetoric, argument, and style, both on the multiple-choice section and in your essays. The exam itself is built around close reading and evidence-based writing, and the terms below map directly onto those skills.

This guide breaks the essential vocabulary into three practical groups: the rhetorical situation, appeals and argument, and style and analysis. Learn them as tools you apply to a passage, not as definitions to recite.

The rhetorical situation: context, purpose, and audience

Every AP Lang passage sits inside a situation. Before you analyze word choice, identify who is speaking, to whom, why, and under what circumstances.

• Rhetorical situation — the full set of conditions surrounding a text: the writer, the audience, the purpose, the context, and the message. Nearly every analysis question begins here.
• Exigence — the spark that makes the writer speak now. A speech delivered the day after a tragedy has a different exigence than an op-ed written a year later.
• Purpose — what the writer wants to achieve: to persuade, inform, entertain, or provoke.
• Audience — the intended readers or listeners, whose values and expectations shape every other choice.
• Persona — the version of the self the writer projects, which may or may not match the real person.
• Tone — the writer’s attitude toward the subject, conveyed through diction and syntax.

The College Board frames the course around exactly this kind of situational reading, so treat these as your starting questions on any prompt.

A quick worked example

Suppose a student council president writes a column asking peers to stop leaving trash in the cafeteria. The exigence is the ongoing mess; the audience is fellow students, not administrators; the purpose is to change behavior, not to vent; the persona is a reasonable peer rather than an authority figure. Those four facts already dictate which appeals and which tone will work.

Appeals, argument, and evidence

This cluster covers how writers build a case and how they earn a reader’s trust. It is the heart of the exam’s argument essay.

• Ethos — an appeal to the writer’s credibility, character, or authority.
• Pathos — an appeal to the audience’s emotions, values, or sympathies.
• Logos — an appeal to logic, reasoning, and evidence.
• Claim — the main assertion a writer asks the audience to accept.
• Evidence — the facts, examples, statistics, or testimony that support a claim.
• Warrant — the often-unstated assumption that links evidence to a claim.
• Concession — an acknowledgment that an opposing point has merit.
• Rebuttal — the response that explains why the writer’s position still holds.
• Qualifier — a word or phrase that limits a claim (“often,” “in most cases”) to make it more defensible.
• Counterargument — the opposing view a writer anticipates and addresses.

A single sentence can carry several of these at once: “While remote work has clear benefits, it often isolates newer employees, and companies that ignore that risk pay for it in turnover.” The concession opens the sentence, the qualifier (“often”) softens the claim, and the causal reasoning supplies the logos. Purdue’s writing resources emphasize that strong arguments anticipate objections rather than ignore them, which is exactly what concession and rebuttal do.

Use a table when you need a fast distinction among the three appeals:

Style and analysis: diction, syntax, and the moves that earn points

AP Lang asks you to explain how a sentence works, not just what it says. These terms let you do it, and the ones at the end describe the language of your own essays.

• Diction — word choice, including its connotation and formality level.
• Syntax — sentence structure, from length and punctuation to the order of clauses.
• Connotation vs. denotation — a word’s emotional associations versus its literal meaning.
• Juxtaposition — placing two items side by side to highlight contrast.
• Antithesis — a balanced contrast within a sentence (“not by power, but by principle”).
• Parallelism — repeated grammatical structure across words or clauses.
• Anaphora — repetition of a word or phrase at the start of successive clauses.
• Metaphor and simile — implied and explicit comparison.
• Hyperbole and understatement — deliberate exaggeration and deliberate restraint.
• Irony and satire — a gap between what is said and meant, and the use of that gap to criticize.
• Allusion — a reference to a well-known text, person, or event.
• Rhetorical question — a question asked for effect, not for an answer.
• Rhetorical analysis — explaining how a text persuades, not merely what it says.
• Line of reasoning — the logical sequence that holds an argument together.
• Commentary — your explanation of why evidence matters, which is distinct from restating it.
• Thesis — the central arguable claim that organizes an essay.
• Shift — a change in tone, focus, or direction, often marked by “but,” “however,” or a new paragraph.

Two sentences, two effects

Compare these openers. “The city council voted.” Five words, flat, neutral—it reports. Now: “After months of hearings, after hundreds of public comments, after a flood of angry emails, the city council finally voted.” The second sentence uses anaphora (“after… after… after”) and delayed syntax to build pressure before the verb. Same event, entirely different rhetorical weight, and that difference is what earns analysis points.

The College Board’s exam pages note that successful essays integrate quotations with commentary rather than dropping evidence in and moving on; the distinction between evidence and commentary matters a great deal. A practical test: if a sentence could have been written without reading the passage, it is probably summary, not analysis.

Key Takeaways

• Learn the terms as tools for the rhetorical situation—speaker, audience, purpose, exigence, context—not as a memorized list.
• Ethos, pathos, and logos work together; strong arguments also concede, rebut, and qualify.
• Diction and syntax create effects you must explain, not merely label. Always connect the device to its purpose.
• Distinguish evidence from commentary. The exam rewards explanation of why a choice matters.
• Build a reusable line of reasoning, and use transitions and shifts to show how an argument develops.
• Practice on real passages so each term becomes a move you can spot and name in seconds.
