Pronunciation

  • Classical: [kɔn.traːˈdɪk.ti.oː][1]
  • Ecclesiastical: [kon.traˈdik.t͡si.o][1]

Forms

contrādictiō f (genitive contrādictiōnis); third declension[1]

Etymology

It is from Latin contrādīcō (“to speak against”) + -tiō.[2][1][3] That verb is formed from contrā (“against”) and dīcō2 (“to say”).[1]

Earliest recorded meaning

Its first known use is in the elder Seneca's Suasoriae, of a counterargument that has been put forward.[2][4][3]

Semantic evolution

Lewis & Short note that it is post-Augustan and most frequent in Quintilian, for the replies and objections of judicial pleading;[5] contradictionem sumere meant to anticipate an opponent's objection.[5] Tacitus uses it of speaking in opposition.[2] Boethius uses it in logic for the opposition of affirmation and negation, a contradiction.[4]

In Medieval Latin it meant a refusal, and the denial or contesting of a right.[6] English contradiction (late 14th century) comes from Old French or directly from it.[7]
