Pronunciation

  • IPA (Classical): [ˈka.we.oː][1]
  • IPA (Ecclesiastical): [ˈkaː.ve.o][1]

Forms

caveō (present infinitive cavēre, perfect active cāvī, supine cautum); second conjugation[1]

Etymology

It is inherited from Proto-Italic *kawē-, inherited from Proto-Indo-European *kouh₁-éie- (“to perceive”).[2] De Vaan explains the /a/ by an unrounding of PIE /ou̯/ before the stress, so that *kou̯(H)-éie- gave *kawē-.[2] The perfect cāvī and the participle cautus are regular from it.[2]

Cognate with Umbrian kutef (“in silence”),[2] Sanskrit कवि (kaví, “seer, poet”), Ancient Greek κοέω (koéō, “to perceive”) and Old High German scouwōn (“to look at”).[2][3][1] Wiktionary adds English show.[1]

Earliest recorded meaning

It is found from Naevius onwards.[2] In Plautus a character says he ought to have taken care before he was ashamed.[3]

Semantic evolution

Its first sense was to be on one's guard, and with an accusative to guard against or avoid a danger, as in Terence's “what you can avoid it's foolish to let happen”.[3] The imperative cave with a subjunctive meant “mind you don't”, and with a dative it meant to look out for someone's interests.[3]

In law it meant to provide for something in a contract or statute, to give a surety or guarantee, and to obtain security from someone, as in Cicero and Caesar.[3] The noun cautiō gave English caution, first “bail, guarantee” about 1300, and the subjunctive caveat, “let him beware”, was taken into English in the 1550s.[4]

Timeline

  • c. 235–200 BC – Naevius uses it.[2][5]
  • c. 250–184 BC – Plautus uses it in the sense “to take precautions”.[3][5]
  • 81–43 BC – Cicero uses it of legal provisions.[3][5]
  • c. 1300 – English caution comes from its derivative cautio.[4]
  • 1550s – English caveat is taken from its subjunctive.[4]
