Forms

toxicō (present infinitive toxicāre, perfect active toxicāvī, supine toxicātum); first conjugation[1]

Etymology

It is from Latin toxicus (“poisoned”).[1] The adjective comes from toxicum (“poison”), from Ancient Greek τοξικόν (toxikón), the poison for arrows, from τόξον (tóxon, “bow”).[2]

Earliest recorded meaning

It is first found in Ambrose, only in the past participle: sagitta toxicata, a poisoned arrow.[3][4]

Semantic evolution

It is a Late and Ecclesiastical Latin word for smearing something with poison.[1][5] Medieval writers use it of poisoned weapons, and the participle as an adjective for anything poisonous, also figuratively, as of poisoned tongues.[6][7] Du Cange cites it from John of Salisbury and Peter of Blois for killing with poison,[8] and Neo-Latin writers still use it of poisoned souls and of a person said to have been poisoned.[9]

It lives on in Italian tossicare, Romanian topseca and Venetan tosegar.[1]

Timeline

  • c. 340–397 AD – Ambrose speaks of a poisoned arrow.[3][4]
  • before 735 – Bede tells of a poisoned dagger.[6]
  • 1115–1143 – William of Malmesbury tells of a poisoned dagger.[6]
  • 1130–1180 – John of Salisbury asks whether it is not madness to poison a serpent.[6][8]
