Iberian

Pronunciation

  • Classical: [kʊˈniː.kʊ.ɫʊs][1]
  • Ecclesiastical: [kuˈniː.ku.lus][1]

Forms

cunīculus m (genitive cunīculī); second declension[1] Paul the Deacon's Festus has a neuter cunīculum in the sense of a tunnel.[2][3]

Etymology

It is perhaps borrowed from Iberian, as Pliny the Elder's report on rabbits in Spain suggests;[2][3][1] Lewis & Short call it Spanish.[2][3][1] Wiktionary suggests an Iberian or Celtiberian word with the Latin diminutive suffix, comparing Basque untxi (“rabbit”).[1] Köbler also mentions a derivation from cunnus.[4] It appears in Greek texts as κόνικλος (kóniklos) or κύνικλος (kúniklos).[3][5]

Earliest recorded meaning

Varro describes it as a third kind of hare, like ours but low, which, he says, is called cunīculus.[2][1]

Semantic evolution

The rabbit is the first sense: Catullus speaks of something softer than a rabbit's fur, and Pliny the Elder of a town in Spain undermined by rabbits.[2] From the animal's burrowing it came to mean an underground passage or burrow: Cicero asks what if a man dug tunnels to the treasury.[2][3] In war it is a mine dug under the walls in a siege, as in Caesar and Livy, and figuratively a secret attack, as Cicero says that what was sought openly is now attacked by mines.[2][3] It is also a water conduit or channel, as in Cicero's case about the waters of the Velinus.[2] Church Latin glosses it a mine.[6]

Timeline

  • c. 50 BC – Caesar of siege mines.[2][4]
  • 81/79–52/50 BC – Catullus of a rabbit's fur.[2][4]
