Pronunciation

  • Classical: [anˈtɪ.dɔ.tũː][1]
  • Ecclesiastical: [anˈtiː.do.tum][1]

Forms

antidotum n (genitive antidotī); second declension[1]

Etymology

It is borrowed from Ancient Greek ἀντίδοτον (antídoton, “remedy against poison”),[2][3][4] the neuter of the adjective ἀντίδοτος (antídotos), which is also behind the less common feminine forms ⟨antidotos⟩ and ⟨antidotus⟩.[3][4] The Greek word means literally “given against”: it is formed from ἀντί (antí, “against”) and the stem of δίδωμι (dídōmi, “to give”).[5][6]

Isidore of Seville explained it as “given from the contrary”, since contraries are cured by contraries.[7][8]

Earliest recorded meaning

It appears in the 1st century AD in the medical writer Celsus, who says that antidotes are seldom but sometimes necessary,[4][5] and in the fables of Phaedrus,[4][9] meaning a remedy against poison.[3][4]

Semantic evolution

Quintilian and Suetonius use it of a counterpoison,[4] and the feminine form antidotus occurs in Gellius.[10] In Spartianus' life of Hadrian it means a remedy of any kind,[10] and it was also used figuratively.[10][11]

In Medieval Latin it meant an antidote or a remedy for poison or disease;[11] Old English glossaries render it with wyrtdrenc, a herbal drink.[11] Christian writers kept the word for a counterpoison or remedy.[12] English took it over in the early 15th century as antidote, partly through Old French.[6]

Timeline

  • 14–37 AD – Celsus discusses antidotes in his work on medicine.[4][5]
  • c. 15 BC–c. 50 AD – Phaedrus uses the word in his Fables.[4][9][5]
  • c. 35–95/96 AD – Quintilian has someone promise to give an antidote.[4][5]
  • c. 165 AD – Gellius uses the feminine form antidotus.[10][5]
  • c. 560–636 AD – Isidore of Seville explains the name as “given from the contrary”.[8][5]
  • early 15th century – English borrows it as antidote.[6]
