Forms

cautor m (genitive cautōris); third declension[1]

Etymology

It is from Latin caveō (“to be on one's guard”) + -tor.[2][3] De Vaan lists it, with cautus, cautiō and cautēla, among the derivatives of the verb found from Plautus on.[3] The verb goes back to Proto-Italic *kawē- and Proto-Indo-European *kouh₁-éie- (“to perceive”).[3]

Earliest recorded meaning

Plautus uses it in the Captivi of a careful man, in a remark that even the man who thinks he has taken precautions is often caught.[4][5]

Semantic evolution

Plautus also uses it, in jest, in the Epidicus, where the wary one is himself caught.[4][6] Cicero uses it of one who wards off danger from another or stands bail for him: the cautor alieni periculi.[7][5][6]

Timeline

  • c. 250–184 BC – Plautus uses it of a wary man.[4][8]
  • 81–43 BC – Cicero uses it of one who guards another against danger.[7][8]

Meanings
