Forms

spēlunca f (genitive spēluncae); first declension[1]

Etymology

It is borrowed from Ancient Greek σπῆλυγξ (spêlunx, “cave”), adapted.[2][3][4] Köbler compares σπήλαιον (spḗlaion, “cave, grotto”) and σπέος (spéos, “cave”).[5]

Earliest recorded meaning

Köbler's first source is Cicero,[5] who has “Philoctetes has now been lying in his cave for ten years”.[3]

Semantic evolution

It is a cave, cavern or grotto, also an animal's den.[2][3] Döderlein distinguishes it from specus and caverna, hollows below or level with the ground: spelunca is a cavity with an opening leading into a mountain, thought of physically, for its darkness and dread, while antrum is a grotto seen as beautiful and cool.[6]

Church Latin glosses it “cave, den, lair”.[7]

Timeline

  • 81–43 BC – Cicero of Philoctetes' cave.[3][5]
  • late 14th century – Borrowed into English as spelunk “cave”, partly through Old French.[4]
