The Complete Glossary of Debate Terms (A-Z, With Examples)

Walk into your first debate tournament and you'll hear 30 words you've never used outside an English class — and 20 more invented by debaters and used by no one else. This glossary exists so you don't have to fake-nod for a season.

Terms are alphabetical. Each entry includes a plain-language definition, the format it's most relevant to, and a usage example. If a term has multiple meanings across formats, the format-specific meanings are listed separately.

How to use this glossary

Read straight through if you're new. Search for specific terms if you're trying to decode a round you just judged. Bookmark it for the first month of competing — most of these become second nature within a season.

Want to hear these terms used in context? You can listen to live or recorded debates on YouTube (search for NSDA Nationals, TOC, or NDT finals), or watch two AIs argue any topic at your own pace on DebateThis — useful for getting fluent with the structure before you sit through your first round.

A

Affirmative (Aff). The side defending or supporting the resolution. In Policy and LD, the Aff usually presents a plan or framework. "The Aff has to win every link in their solvency chain."

Apriori. An argument that, if won, automatically wins the round regardless of other arguments. Rare and contested. "They're running an apriori on framework — if you buy it, the substance debate doesn't matter."

Argumentation. The skill of building and defending positions. Distinct from rhetoric (which is style); argumentation is structure.

Attack. A direct refutation of an opponent's claim. "I have three attacks on their second contention."

B

Bid. Qualification for a major tournament (most often the Tournament of Champions). Earned by reaching late elimination rounds at qualifying tournaments. "They got a TOC bid at Glenbrooks."

Block. A pre-written response to an argument the opposing team is likely to run. Debate teams spend hours building blocks for common positions. "Pull our K block — they're running cap."

Burden of proof. The obligation a side has to support its claims. In most formats, the Aff has the burden of proof for the resolution. "The Aff has the burden of proof; they have to prove the resolution is true."

C

Card. A piece of evidence — typically a quoted passage from an article, with citation. Comes from the era when evidence was literally written on index cards. "They read three cards on inherency."

Carded. Said of an argument supported by evidence. The opposite is "uncarded" or "analytic." "That's a carded warrant — they have a study backing it."

Case. A debater's full set of prepared arguments on a particular side of the resolution. "Our Aff case has two contentions and a counter-plan."

Clash. Direct engagement between opposing arguments. Judges look for clash; rounds without it feel like two parallel monologues. "There was no clash on the first contention — they just talked past each other."

Closing argument. The final speech of a round. In most formats it's a summary plus a final pitch to the judge. Cannot introduce new arguments.

Conditionality (Cond). The right to drop arguments mid-round in formats that allow it (mainly Policy). Heavily contested theoretically.

Constructive. A speech that introduces new arguments. Distinguished from "rebuttal" speeches, which respond to existing arguments.

Contention. A main argument in a case. Most PF cases have 2-3 contentions; LD cases often have 1-2. "Their first contention is on economic impacts; the second is on geopolitical."

Counter-plan (CP). A Negative argument that proposes an alternative to the Aff's plan, claiming the alternative solves the harms better. "Their counter-plan is to do the plan but only in one state."

Cross-examination (CX, Cross-X, Cross). A period where one debater questions another. Format-specific: in Policy it's 3 minutes; in LD it's 3 minutes; in PF there's a 3-minute "crossfire."

D

Disad / Disadvantage (DA). A Negative argument that the Aff's plan causes a bad outcome. The classic DA structure: uniqueness + link + impact. "They're running a politics DA — passing the plan tanks Biden's political capital."

Drop. Concede an argument by not responding to it. A dropped argument is "extended" by the side that introduced it. "They dropped our impact — we're going to extend it."

Drop the argument (DTA) vs. Drop the debater (DTD). Common theory arguments. DTA = if you win this theory argument, you just kick out the bad practice. DTD = you win the round.

E

Evidence. Cited material used to support claims. Stronger evidence = more recent, more credentialed source, more direct on the point. "Their evidence is from 2019 — we have 2026 evidence on the same point."

Extend. To carry an argument forward in a later speech. "I'm extending our first contention into the rebuttal."

Extempore (Extemp). A separate competitive speech category, not technically debate. Speakers get 30 minutes to prepare a 7-minute speech on a current-events question.

F

Flow. (1) The notes a judge or debater takes during a round, tracking arguments and responses. (2) The act of taking those notes. "They didn't flow our 4th response, which is why they dropped it."

Framework. The standard by which the round should be evaluated. In LD, framework debate (value + criterion) is central. In Policy, framework is often about whether the round should be policy-focused or critical. "Their framework is 'minimize structural violence.'"

G

Going for. Choosing to focus on one argument in your final speech. "I'm going for the topicality argument in the 2NR."

H

Harms. The negative consequences of inaction or maintaining the status quo. The Aff usually argues that harms exist; the Neg argues that they don't or aren't significant.

I

Impact. The ultimate consequence of an argument. "The impact of their disad is nuclear war." Impacts are weighed against each other to determine which side's world is worse.

Inherency. The barrier that prevents the status quo from solving the problem. Aff has to prove the harm wouldn't go away on its own.

J

Judge philosophy / paradigm. A document where a judge explains how they evaluate rounds. Critical to read before competing. "Their paradigm says they don't vote on theory — focus on substance."

K

Kritik (K). A philosophical critique of the resolution itself, the opposing side's assumptions, or the practice of debate. "They're running a cap K — capitalism is the root cause."

L

Lay judge. A judge without formal debate training (often a parent volunteer). Adapt your speed and jargon. "It's a lay panel — slow down and explain everything."

Link. The argument that connects two ideas — usually that the Aff's plan causes the DA's impact. "Their link is weak; the plan doesn't actually trigger their disad."

M

Member of Parliament (MP). Speaker role in World Schools and Parliamentary debate.

N

Negative (Neg). The side opposing the resolution.

O

Off-case. Arguments introduced by the Neg that aren't direct attacks on the Aff case — DAs, CPs, Ks, topicality. "They ran three off-case positions."

Opening. The first speech of a round. Lays out the case and primary arguments.

P

Paradigm. See "Judge philosophy."

Perm / Permutation. An Aff response to a counter-plan, arguing that the Aff can do both the plan AND the CP. "Perm: do both."

Plan. A specific policy proposal the Aff is defending. Required in Policy; less common in PF and LD.

R

Rebuttal. A speech that responds to the opposing side's arguments. Distinguished from "constructive" speeches that introduce new arguments.

Resolution. The topic statement being debated. "The resolution is: The U.S. should adopt single-payer healthcare."

Round. A single debate match. Tournaments have multiple rounds.

S

Sign-post. A clear verbal cue that you're moving to a new argument. "My second response: ..."

Solvency. The argument that a plan actually solves the problem it's designed to solve. "They have no solvency — their evidence doesn't prove the plan works."

Speed (Spreading). Speaking very fast to fit more arguments into a speech. Common in Policy and some LD. Controversial — most paradigms discourage it.

T

Tab. The tournament administration desk. Where pairings are posted and judges check in. "They posted Round 3 at tab."

TOC (Tournament of Champions). The most prestigious U.S. high school debate tournament, held at the University of Kentucky. Bid-only.

Topicality (T). An argument that the Aff's plan doesn't meet the resolution. Procedural — if T wins, the Aff loses regardless of substance.

Turn. An argument that the opposing side's position actually helps your side. "That's a link turn — their evidence supports our case."

U

Uniqueness. In DA debate, the argument that the DA's impact will happen only if the plan passes. Without uniqueness, the impact already exists and the plan doesn't cause it.

V

Value (LD). The core moral principle the debater is defending. Common values: justice, freedom, morality, equality.

Value criterion (LD). The standard for weighing the value. "My value is justice; my criterion is maximizing equal opportunity."

Voter. A reason the judge should vote a particular way. Standard in final rebuttals. "Three voters: solvency, magnitude of impact, and probability."

W

Warrant. The reasoning that supports a claim. A claim without a warrant is an assertion. "They have a claim but no warrant — why would the plan cause the impact?"

Weigh / Weighing. Comparing the importance of competing arguments. "Weigh our impact against theirs — ours is more probable and more severe."

Z

Zero risk. An argument that the opposing side has no probability of winning a particular argument. Rare and often abused. "They're saying there's zero risk of the DA — but they didn't refute the link."

What to do with this glossary

Don't memorize it. Read it once, then refer back to it as you sit through real rounds. Most of these terms only make sense in context — you'll absorb them naturally over a season of competing or judging.

If you want to accelerate the absorption, watch debates in your preferred format on YouTube with the glossary open. Pause when you hear a term you don't recognize, look it up, then keep going. After about 10 hours of round-watching, the vocabulary becomes background.

Or run free-form rounds on DebateThis and pay attention to how the AI scorer breaks down the round — substance, structure, evidence, clash. Those four scoring categories map directly to four of the most important concepts in this glossary, and they'll show up over and over in judge feedback at real tournaments.
