Pronunciation

  • Classical: [ɪnˈniː.tɔr][1]
  • Ecclesiastical: [inˈniː.tor][1]

Forms

innītor (present infinitive innītī, perfect active innīxus sum or innīsus sum); third conjugation, deponent[1] The perfect participle is usually innīxus;[2][3] innīsus is found in Tacitus.[2][3]

Etymology

It is from Latin in- (“on”) + nītor (“to lean, strive”).[2][3][1] De Vaan reconstructs nītor as Proto-Italic *kniχw-et- and, with Walde–Hofmann and Pokorny, connects it with cōnīveō (“to be tightly closed”); he notes that the verb's first meaning could have been either to lean on or to exert pressure.[4]

Earliest recorded meaning

The earliest example in the OLD is in Caesar's Gallic War, of soldiers who fought on leaning on their shields.[2][5]

Semantic evolution

It is to lean on something for support, usually with the dative: Ovid has a man leaning on his spear, and Propertius one resting on his right shoulder.[2][6] The participle in the phrase innīxus genū, “the kneeler”, was a name of the constellation Hercules.[2] Things rest on supports too, as a house on Phrygian columns, and an elephant presses its weight on a man with its knee in the Bellum Africum.[2] Figuratively it is to depend or rely on, as when Livy writes that the fortune of the enemy rests on one man.[2] Church Latin uses it chiefly for relying on God.[7]

Timeline

  • c. 50 BC – Caesar of soldiers leaning on their shields.[2][5]
  • 59 BC–17 AD – Livy of fortune resting on one man.[2][5]
  • 98–115 AD – Tacitus has the participle innīsus.[2][3][5]
