Pronunciation

  • Classical: [ɔk.kɪ.dɛnˈtaː.lɪs][1]
  • Ecclesiastical: [ot.t͡ʃi.denˈtaː.lis][1]

Forms

occidentālis (neuter occidentāle); third-declension two-termination adjective[1]

Etymology

It is formed from Latin occidēns + -ālis,[2][1] the noun occidēns meaning “west”.[1] Köbler refers it further to occidō2 (“to fall, set”).[3]

Earliest recorded meaning

Lewis & Short and Gaffiot first cite it from Pliny the Elder in the 1st century AD, who speaks of the western side of the north;[4][5][3] the TLL counts it only from Gellius on and discusses the Pliny passage separately.[6]

Semantic evolution

Lewis & Short note that it is post-Augustan.[4] Gellius has the west wind, ventus occidentalis, and Ammianus Marcellinus a western star.[4][6] In Late Latin it described the Western provinces and their bishops, as against the East,[6] and Chalcidius used the neuter plural occidentālia as a noun for the West.[7] The Vulgate speaks of the western sea.[4]

In Medieval Latin it marked one of the four quarters of the world, western kingdoms and jurisdictions and the Western church, and as a noun a westerner.[8] English occidental came from Old French and directly from Latin about 1400.[9]

Timeline

  • 23/24–79 AD – Pliny the Elder speaks of the western side of the north.[4][5][3]
  • c. 165 AD – Gellius names the west wind ventus occidentalis.[6][4][3]

  • c. 383–419/420 AD – Jerome writes of the western provinces.[6][3]
  • c. 1400 – English borrows it as occidental.[9]
