Pronunciation

  • Classical: [ʊŋˈkiː.nʊs][1]
  • Ecclesiastical: [un̠ʲˈt͡ʃiː.nus][1]

Forms

uncīnus m (genitive uncīnī); second declension[1]

Etymology

It is formed from Latin uncus (“hook”) + -īnus;[2][3][4] Wiktionary calls it a diminutive of the noun.[1] The base goes back to Proto-Italic *onko- and Proto-Indo-European *h2onḱ-o- (“hook”).[5] Cognate with Sanskrit अङ्क (aṅká-, “hook, clamp”) and Ancient Greek ὄγκος (ónkos, “barb of an arrow”).[5]

Earliest recorded meaning

Vitruvius is the first author the dictionaries cite for it,[3][6][7] with an iron hook (uncinus ferreus).[3]

Semantic evolution

Lewis & Short treat it as a late word that took the place of uncus for a hook or barb.[8] Apuleius and Palladius use it,[3][8] Isidore of Seville speaks of hooks of iron or of wood,[3] an inscription lists poles with hooks (perticae XII uncinorum),[3] and the Vulgate has it in Exodus.[8]

In British Medieval Latin it is still a hook, also in figurative use: Bede writes of hooks with golden chains hanging from them, and of the hook of good works (boni operis uncinus).[9] It lives on in Italian uncino.[7][10]

Timeline

  • c. 84–c. 25 BC – Vitruvius writes of iron hooks.[3][11]
  • c. 125–175 AD – Apuleius uses it in the Metamorphoses.[3][6][11]
  • 390–406 AD – The Vulgate uses it in Exodus.[8][11]
  • end of the 4th or beginning of the 5th century AD – Palladius uses it.[3][11]
  • c. 560–636 AD – Isidore of Seville mentions hooks of iron or wood.[3][11]
