A claim supported by reasons and evidence, intended to persuade a reasonable audience; distinct from an opinion, which needs no support.
Thesis
The central, debatable claim of an argument, stated clearly and defended throughout the paper or presentation.
Claim
An assertion that something is true, valuable, or should be done. Each body paragraph typically advances one claim that supports the thesis.
Evidence
Facts, data, examples, testimony, or scholarship used to support a claim; must be credible, relevant, and sufficient.
Reasoning (commentary)
The explanation that connects evidence to a claim; the writer's own analysis showing why the evidence matters.
Line of reasoning
The ordered chain of claims, each supported by evidence and commentary, leading logically to the conclusion. It should be traceable at a glance.
Warrant
The often-unstated assumption that links evidence to a claim in the Toulmin model; if the audience rejects the warrant, the evidence fails to persuade.
Toulmin model
Framework of claim, grounds (evidence), warrant, backing, qualifier, and rebuttal for building and analyzing arguments.
Qualifier
Language such as 'often,' 'in most cases,' or 'to a large extent' that limits a claim to what the evidence can support.
Rebuttal
A response that shows why an opposing argument is weaker, flawed, or outweighed.
Concession
Acknowledging that part of an opposing view is valid before explaining why one's own claim still holds.
Counterargument
The strongest reasonable objection to a thesis, presented fairly. Top rubric levels require engaging real counterarguments, not straw men.
Straw man
A fallacy that misrepresents an opposing view as weaker or more extreme than it is, then attacks the distortion.
Ad hominem
A fallacy attacking the person making an argument instead of the argument itself.
Hasty generalization
A fallacy drawing a broad conclusion from too few or unrepresentative examples.
False dilemma
A fallacy presenting only two options when more exist ('either we ban phones or students will fail').
Slippery slope
A fallacy claiming one step will inevitably lead to extreme consequences without evidence for the chain.
Appeal to authority (misused)
Citing an authority outside their field or treating authority as proof rather than evidence.
A fallacy assuming that because B followed A, A caused B.
Circular reasoning
Using the claim itself as evidence for the claim ('this policy is right because it is the correct policy').
Ethos
Persuasive appeal based on the credibility and character of the speaker or the sources cited.
Logos
Persuasive appeal based on logic, evidence, and structured reasoning; the primary mode expected in Seminar arguments.
Pathos
Persuasive appeal to the audience's emotions and values; effective when paired with logos, weak when used alone.
Inductive reasoning
Reasoning from specific observations to a general conclusion; conclusions are probable, not certain.
Deductive reasoning
Reasoning from general premises to a specific conclusion; valid structure plus true premises yields a certain conclusion.
Sufficiency of evidence
Whether enough evidence of the right kinds supports a claim; one study rarely settles a complex question.
Relevance of evidence
Whether evidence actually bears on the specific claim rather than a related but different point.
Solution or resolution
The IWA and presentation typically move from problem to a proposed solution, resolution, or recommendation, evaluated for feasibility and consequences.
Implications and consequences
What follows if the argument is accepted, including unintended effects; strong arguments address them.
Nuance
Recognizing degrees, exceptions, and trade-offs rather than presenting an issue as simple; a hallmark of higher rubric scores.
Complexity of argument
Handling competing perspectives and acknowledging limitations while still advancing a clear thesis.
Signposting
Explicit transitions ('First,' 'However,' 'Given this evidence,') that make the line of reasoning easy to follow.
Topic sentence
The first sentence of a paragraph stating its claim and its link to the thesis; anchors the line of reasoning.
Integrating evidence
Introducing a source, presenting the evidence, and then explaining its significance rather than dropping quotations without context.
Attribution
Naming the source of evidence in the text ('According to a 2022 CDC report...') to build ethos and support citation.
Conclusion
The final section that restates the resolved thesis, addresses implications, and leaves the audience with a clear takeaway; not a mere summary.
