Definition
To contradict a witness is to introduce evidence proving that a fact to which the witness testified is otherwise than as the witness stated. In practice, contradiction is a specific form of witness impeachment: rather than attacking the witness's general credibility or character, it targets a particular factual assertion and offers contrary proof. The goal is to show that the witness was wrong — whether from mistake, faulty memory, or deliberate untruth — on a specific point, not to disqualify the witness altogether.
Contradiction is distinct from impeachment by prior inconsistent statement, though the two overlap conceptually. Contradiction typically involves extrinsic evidence (testimony of another witness, a document, physical evidence) demonstrating that the disputed fact is not as the first witness described it. Prior inconsistent statements impeach by showing the witness has said something different at another time; contradiction shows the world is different from what the witness claimed.

Common Language
Modern common usage (Wiktionary): To deny the truth or validity of a statement; to oppose a person by denying what they have said; to be contrary to something; to say things that conflict with each other.
Historical common usage (Webster's 1913): To assert the contrary of; to oppose in words; to take issue with; to gainsay; to deny the truth of a statement or speaker.
The common meaning is broad — contradiction covers any assertion that opposes another. The legal meaning is narrower and procedural: it refers specifically to the evidentiary act of proving a witness wrong on a particular fact through contrary evidence in the record. In law, you do not contradict someone merely by saying they are wrong; you contradict them by producing proof that the fact is otherwise.

Common Confusion
CONTRADICT vs. IMPEACH: These terms are frequently used interchangeably in everyday speech but carry distinct meanings in evidence law. Impeachment attacks the witness's general credibility — through bias, prior convictions, character for untruthfulness, or prior inconsistent statements. Contradiction attacks a specific factual claim the witness made by proving the fact is otherwise. A party may contradict its own witness on a particular fact; the older rule (still operative in many jurisdictions) prohibited a party from impeaching its own witness on general credibility grounds. This distinction is legally significant, and the historical sources draw it explicitly.
CONTRADICT vs. REBUT: To rebut is to counter an opposing party's evidence generally, often at a designated stage of trial. To contradict is the specific act of disproving a particular witness's factual assertion. Anderson directs readers to REBUT, signaling the concepts are related but not synonymous.

Why It Matters in Research
The critical research trap here is the collateral matters doctrine. Contradiction is not unlimited: courts restrict the use of extrinsic evidence to contradict a witness on collateral matters — points not independently relevant to the case other than as they reflect on the witness's credibility. A researcher encountering contradicting evidence arguments in historical pleadings or appellate records must determine whether the contested fact was collateral, because the admissibility of the contradicting evidence turns on that classification. This doctrine is live, contested, and jurisdiction-sensitive, and its application varies considerably across the corpus.
In historical sources, contradiction appears almost exclusively in the evidentiary practice context — proving a fact otherwise than a witness stated — and the vocabulary is stable from Bouvier through the early twentieth century. Researchers working with pre-Federal Rules materials should note that the party's right to contradict its own witness was a significant procedural battleground; common law courts were more restrictive than modern rules. FRE 607 (permitting any party to impeach any witness) changed the landscape, but it did not eliminate the separate analytical category of contradiction.
The cross-reference to PAROL in Anderson is worth noting: contradiction of written instruments by parol (oral) evidence implicates the parol evidence rule, a separate doctrinal area. A researcher must distinguish contradiction of a witness's testimony from contradiction of a contract or deed's written terms — the latter raises entirely different rules.
Watch for terminological slippage in nineteenth-century reports where "impeach" and "contradict" are sometimes used interchangeably even by courts. The more precise distinction is in the treatise literature (Greenleaf, cited in Bouvier, is the key authority) rather than in many judicial opinions of the period.

Historical Dictionary Support
The historical sources are in agreement on the core definition and remarkably consistent across editions. Black's (both editions), Bouvier, and Rapalje & Lawrence all define contradiction in nearly identical terms: proving a fact contrary to what a witness has asserted. The formulation is stable, suggesting this was settled usage by the mid-nineteenth century.
Bouvier offers the most substantive treatment, citing Greenleaf's Evidence and a series of state court decisions to support the proposition that a party may contradict its own witness on a particular fact but may not impeach that witness's general character. This party-witness distinction was a practical concern in an era when parties themselves were incompetent witnesses; the rule mattered most when a party called a witness who then gave unhelpful testimony. Bouvier's citations point researchers toward the foundational treatise and case law corpus for this doctrine.
Rapalje & Lawrence sharpens the definition slightly: contradiction proves a fact "to be otherwise than as stated by the witness" — emphasizing that the contradicting party must actually produce contrary proof, not merely argue the witness is wrong. The cross-reference to IMPEACHMENT in Rapalje is the correct navigational signal for researchers who need the full framework.
Anderson's entry is minimal, cross-referencing only PAROL and REBUT, which likely reflects a judgment that the term was sufficiently understood and that the interesting doctrinal questions arose under those neighboring concepts.
What the historical sources collectively omit is any treatment of the collateral matters limitation — a doctrine well understood by contemporaneous courts and treatise writers but not spelled out in these dictionary entries. Researchers relying solely on dictionary definitions would miss the most litigated aspect of contradiction doctrine.

Jurisdictional Note
Federal courts apply FRE 607 and 613 to questions of witness contradiction and impeachment, and the collateral matters limitation operates as a common-law gloss on the rules rather than as a codified restriction. State courts vary: some have codified the collateral matters doctrine, others apply it through case law, and a few have relaxed it significantly. Historical research in state records requires attention to the specific jurisdiction's rules, which often tracked common law more closely than modern federal practice.
