Pronunciation

  • Classical: [ɛ.pɪˈɫeːp.tɪ.kʊs][1]
  • Ecclesiastical: [e.piˈlɛp.ti.kus][1]

Forms

epilēpticus (feminine epilēptica, neuter epilēpticum); first/second-declension adjective[1] Late spellings include epilempticus and epilenticus.[2][3]

Etymology

It is borrowed from Ancient Greek ἐπιληπτικός (epilēptikós, “epileptic”),[4][5][6] from ἐπίληψις (epílēpsis, “seizure; epilepsy”), the noun of ἐπιλαμβάνω (epilambánō, “to seize”).[5][7]

Earliest recorded meaning

A passage of Ulpian in the Vatican Fragments names the epileptic among those who are excused,[2] Calcidius speaks of an epileptic fall,[8][5] and Firmicus Maternus uses it as a noun in his astrology,[2][9][5] meaning a person suffering from epilepsy.[2]

Semantic evolution

The native Latin name of the illness was morbus comitialis, so epileptica passio in Caelius Aurelianus is a medical loan term.[8][9] Medical writers such as Marcellus glossed the epileptics as those “whom they call caduci”,[2] and Pseudo-Apuleius equated them with the possessed.[2]

Medieval writers used the adjective with morbus and passio for epilepsy and the noun for the patient;[3][10] British sources have it from the 12th century.[6] English epileptic came through French about 1600.[7]

Timeline

  • c. 300 AD – Calcidius speaks of an epileptic fall.[8][5]
  • 343/350 AD – Firmicus Maternus names epileptics among those born under certain stars.[2][9][5]
  • 5th century AD – Caelius Aurelianus uses epileptica passio for the disease.[9][5]
  • 538/539–594 AD – Gregory of Tours uses the form epilenticus.[2][5]
  • c. 1600 – English borrows epileptic through French.[7]
