Pronunciation

  • 5th-century BC Attic: /pé.la.ɡos/[1]
  • 4th-century AD Koine: /ˈpe.la.ɣos/[1]
  • 10th-century Byzantine: /ˈpe.la.ɣos/[1]

Forms

πέλᾰγος (pélagos) n (genitive πελᾰ́γους); third declension[1]

Etymology

The origin is disputed.[1] Frisk connects it with πλάξ (pláx, “flat surface, plain of the sea”) and πλάγιος (plágios, “athwart, sloping”), and Chantraine with πελανός (pelanós), from a base Proto-Indo-European *peləg- with the suffix seen in τέναγος (ténagos, “shallow water”).[2][3] Πάπυρος likewise traces it to the root Proto-Indo-European *pelh₂- (“flat, broad, spread out”).[4] Beekes objects that nothing confirms a link with that root and that the link with those stems is phonetically impossible, and considers it more probably Pre-Greek, from Pre-Greek.[5] A comparison with a Hebrew word for “canal” is rejected.[6]

Earliest recorded meaning

It is found from Homer on, for the open sea: in the Iliad the “great sea”, and in the Odyssey the phrase ἁλὸς ἐν πελάγεσσιν “in the expanses of the sea”.[3][7][8]

Semantic evolution

Chantraine notes that it is distinct both from ἅλς (háls) and θάλασσα (thálassa), the ordinary word for the sea: πέλαγος is the high sea, the open expanse.[3] From Pindar and Herodotus on it names particular seas, with the name of the sea in the genitive or as an adjective, and the tragedians use it figuratively for a sea of troubles.[8][9] Aristotle contrasts the open sea with the shallow water of harbours.[10]

Latin borrowed it as pelagus.[11] Medieval Greek also had the popular forms πέλαγο and πέλαο, which survive in Modern Greek dialects; standard Modern Greek πέλαγος (pélagos) is the learned continuation, meaning the open sea or a named part of the sea.[12][13]
