Pronunciation

  • Classical: [ɔbˈniː.tɔr][1]
  • Ecclesiastical: [obˈniː.tor][1]

Forms

obnītor (present infinitive obnītī or obnītier, perfect active obnīxus sum or obnīsus sum); third conjugation, deponent[1]

Etymology

It is from Latin ob- + nītor (“to lean on, strive”).[2][1][3] De Vaan finds the original meaning of nītor unclear, "lean on" or "exert pressure", and reconstructs Proto-Italic *kniχw-et- with a velar-final root, comparing cōnīveō (“to close the eyes”).[4]

Earliest recorded meaning

Lucretius has it first, with the old infinitive ⟨obnītier⟩: ships seem to push against the waves with broken sterns.[2][5]

Semantic evolution

Lewis & Short call it mostly poetic and post-Augustan, and not found in Cicero or Caesar.[5] It is to press against something, and to resist pressure: Celsus uses it of a swelling held back by the membrane.[2] In Virgil it is to make a stand: a bull pushes against its opponent, and bees strive not to yield.[2][5] Velleius uses it of resisting someone's plans.[2] The participle ⟨obnīxus⟩ is used as an adjective, steadfast.[2][5] Church Latin glosses it to strive, struggle, press.[6]

Timeline

  • 96–55 BC – Lucretius of ships pushing against the waves.[2][5][7]
  • 70–19 BC – Virgil of a bull and of bees.[2][5][7]
  • 14–37 AD – Celsus of a swelling.[2][7]
