Pronunciation

  • IPA (Classical): [adˈwɛr.sʊs][1]
  • IPA (Ecclesiastical): [adˈvɛr.sus][1]

Forms

adversus (feminine adversa, neuter adversum, comparative adversior, superlative adversissimus), first/second-declension adjective, also an adverb and a preposition with the accusative (adversus, adversum).[2][3]

Etymology

It is the perfect participle of advertō “to turn towards”.[2][1][4] Plautus, Terence and others have the older ⟨advorsus⟩, and inscriptions ⟨atversus⟩ and ⟨arvorsum⟩.[2] The adverb and preposition ⟨adversus⟩, ⟨adversum⟩ “facing, against” come from the adjective.[2]

Earliest recorded meaning

The OLD's earliest citation for the adjective is from Cato, of facing.[2] Köbler's first source for the preposition is Plautus, and for the participle the Law of the Twelve Tables, which he dates about 450 BC.[5]

Semantic evolution

It meant turned towards, facing, opposite, and lectus adversus was the marriage bed opposite the door, as in Cicero.[2] It meant lying in one's way, mutually opposed, diametrically opposite in astronomy, directed to the front, and of light or wind falling full on something.[2] Wounds adversa were received in front, facing the enemy.[2] Of slopes it meant rising, adversō colle “uphill”, and adversō flūmine “upstream”, and of winds contrary.[2] It meant ranged against in war, hostile, opposed in opinion, of gods and omens unfavourable, and of times and events adverse, so that rēs adversae meant misfortune, as in Plautus.[2] Pliny uses it of what is contrary in kind.[2]

In Ecclesiastical Latin it meant turned toward, opposite, facing.[6] English adverse came in the late 14th century through Old French advers, and English adversary from its derivative adversārius.[7]

Timeline

  • c. 450 BC – The Law of the Twelve Tables has the word, according to Köbler.[5]
  • c. 250–184 BC – Plautus uses rēs adversae and the preposition.[2][5]
  • 234–149 BC – Cato uses it of facing.[2][5]
  • 81–43 BC – Cicero uses it of contrary winds and hostile opinions.[2][5]
  • late 14th century – English adverse is recorded.[7]
