Pronunciation

  • IPA (Classical): [ˈwɛ.toː], [ˈwɛ.tɔ][1]
  • IPA (Ecclesiastical): [ˈvɛː.to][1]

Forms

vetō (present infinitive vetāre, perfect active vetuī, supine vetitum); first conjugation[1]

Etymology

The origin is uncertain: the OLD and Lewis & Short call it doubtful.[2][3] The older form is votō, used in the manuscripts of Plautus.[2][3] Wiktionary suggests it is perhaps inherited from Proto-Italic *wotāō or *wotaō, the first from Proto-Indo-European *woth₂-eh₂-yeti, the second from Proto-Indo-European *woth₂-éye-ti.[1] Georges compared Greek Ancient Greek ἐτώσιος (etṓsios, “vain, fruitless”).[4]

Earliest recorded meaning

Plautus uses it, in the form votō, to forbid something, as in “what I had forbidden, you avoided”.[2][3] Köbler dates Plautus c. 250–184 BC.[5]

Semantic evolution

The core sense is to forbid an action or to forbid someone to do something, with an infinitive, an accusative and infinitive or nē.[2][6] In politics it meant to reject a proposal: tribes that voted against a law were said to vetāre, and vetō “I forbid” was the formula of the tribunes of the plebs blocking a measure.[2][6] Things too could forbid or prevent, such as an oak blocking the sun in Seneca's tragedy.[2] Döderlein distinguishes vetāre, forbidding by law, opposite iubēre, from interdīcere, forbidding by official authority.[7] The perfect vetāvī is poetic and late, as in the Vulgate.[3]

English veto was taken from the tribunes' formula in the 1620s.[8]

Timeline

  • c. 250–184 BC – Plautus uses the form votō.[2][5]
  • 59 BC–17 AD – Livy reports the tribunes' formula vetō.[6][5]
  • 390–406 AD – The Vulgate uses the perfect vetāvī.[3][5]
  • 1620s – Borrowed into English as veto.[8]
