Forms
interrogātiō f (genitive interrogātiōnis); third declension[1]
Etymology
It is from Latin interrogō (“to question”) + -tiō.[2][1] interrogō is inter (“between”) and rogō (“to ask”), which de Vaan explains as a verb made from a noun Proto-Italic *rogo- (“request; stretching out”), from Proto-Indo-European *h₃roǵ-o- (“stretching”), perhaps of the arms when begging.[1][3]
Earliest recorded meaning
Köbler dates it from Cicero,[4] who speaks of someone obstructing the cause of the tax farmers with very stupid questions.[2]
Semantic evolution
It is the putting of questions, especially the examination of witnesses, as Tacitus' frequent questions that made the watchword known, and a single question or inquiry.[2][5] In rhetoric it is the figure of the rhetorical question, and in philosophy an argument conducted by question and answer, a syllogism, as Cicero speaks of those who conclude nothing by a proper argument.[2][1] The Itala and the Vulgate use it in the First Epistle of Peter of baptism as the appeal or pledge of a good conscience.[6][7] In Medieval Latin it is a hearing or session, a formal demand, a claim and a tallage.[8] English interrogation (late 14th century) is from Old French or directly from Latin.[9]
