Pronunciation

  • 5th-century BC Attic: /lák.kos/[1]
  • 4th-century AD Koine: /ˈla.kos/[1]
  • 10th-century Byzantine: /ˈla.kos/[1]

Forms

λᾰ́κκος (lákkos) m (genitive λᾰ́κκου); second declension[1]

Etymology

It is perhaps inherited from Proto-Hellenic *lə́kwos,[1] inherited from Proto-Indo-European *lókus (“lake, pond”).[1][2] Beekes, following Schrijver, would have to start from a zero grade *l̥kʷo- and notes that the change of /kʷ/ to ⟨κκ⟩ is unexpected;[2] Chantraine finds a form with ⟨κϝ⟩ plausible, comparing ἵκκος (híkkos) beside ἵππος (híppos).[3]

Greek has an o-stem where western and northern languages have a u-stem: Latin lacus (“lake, pond, pit”), Old Irish loch (“lake, pond”) and Old Saxon lagu (“lake, water”).[2][3] Babiniotis gives the same comparison.[4]

Earliest recorded meaning

It is first found in Herodotus, of a pit or reservoir and of a pond in which water-fowl were kept.[5][6]

Semantic evolution

In Attic it is above all a storage pit dug in the ground and lined, for water, wine, oil or grain: a cistern or tank in Aristophanes and Demosthenes, pits for wine and grain in Xenophon.[7][5] Dionysius of Halicarnassus used it to render the Roman Lacus Curtius.[5]

The Septuagint uses it for the pit into which Joseph is thrown, for a dungeon and for the lions' den, and figuratively for the “pit” of misery and of death in the Psalms; the den of lions recurs in early Christian writers.[8][5][9] The philosopher Porphyry called the Sea of Galilee a mere “pond” in contempt.[5]

Medieval Greek used it for a pit, a cistern or well, a ditch or trench and a grave.[10] Today Modern Greek λάκκος (lákkos) is a hole or pit in the ground and colloquially a grave.[11] The phrase “the split-pea purée has some hole in it” says that something is fishy.[11]
