Argument Structure

A series of propositions or claims where each point logically follows from the previous one, building toward a conclusion.

"The lawyer constructed a logical chain of evidence that made the defendant's guilt unavoidable."

"The strength of an argument depends on whether the premises are credible and whether they adequately support the conclusion."

To provide evidence, reasoning, or proof that supports an assertion or assertion sufficiently.

"The researcher substantiated her claims with extensive empirical data and peer-reviewed studies."

"The presenter anticipated counterarguments and addressed them preemptively, strengthening her overall position."

The logical consistency and unified direction of an argument from opening through conclusion.

"Despite raising multiple points, the essay maintained argumentative coherence by consistently returning to the central thesis."

To strengthen a position through additional evidence, refining logic, or addressing potential objections.

"The debater fortified her argument by introducing new statistical evidence that countered the opposition."

A flaw in reasoning that invalidates an argument, such as circular logic, ad hominem, or false dilemma.

"The proposal relied on a logical fallacy by assuming that correlation necessarily implies causation."

The facts, statistics, examples, or expert testimony that validate an argument's claims.

To identify and articulate a logical flaw or unsubstantiated claim in another's argument.

"The rebuttal exposed a weakness in the original proposal by showing it relied on outdated statistical models."

To directly confront anticipated criticisms or concerns rather than ignoring or deflecting them.

"The presenter addressed objections head-on, demonstrating how the proposed solution handles edge cases."

To emphasize that a conclusion inevitably follows from the premises presented.

"The argument underscores the logical necessity of policy reform by showing how current approaches systematically fail."
