Pronunciation

  • 5th-century BC Attic: /kóŋ.kʰos/[1]
  • 4th-century AD Koine: /ˈkoŋ.xos/[1]
  • 10th-century Byzantine: /ˈkoŋ.xos/[1]

Forms

κόγχος (kónkhos) m (genitive κόγχου); second declension[1] Also feminine in Polybius and Pausanias.[2][3]

Etymology

It is the masculine beside κόγχη (kónkhē, “mussel, cockle”), with the same meaning.[4][5] Beekes considers the word Pre-Greek, because it is clearly related to κόχλος (kókhlos, “spiral shell, snail”), the pair showing the prenasalization typical of Pre-Greek words, and because Aristotle's text has variants such as κοκάλια (kokália) and κωκάλια (kōkália).[4]

It has long been compared with Sanskrit शङ्ख (śaṅkhá, “mussel, conch”), from which some reconstruct Proto-Indo-European *ḱongʰ- (“shell, mussel”), but no common pre-form can be set up, and the Greek and Sanskrit aspirates do not correspond regularly.[4][1] If the comparison is right, the Greek and the Sanskrit words may be loans from a common source.[4][1] From κόγχη came Latin concha,[4] and Saalfeld lists conchis as borrowed from κόγχος itself.[6]

Earliest recorded meaning

The earliest records are a fragment of Aeschylus and one of Epicharmus, where it means a mussel or cockle, the same as κόγχη (kónkhē).[2][4]

Semantic evolution

Like κόγχη (kónkhē), it soon named a shellful and things shaped like a shell.[2][3] The comic poet Phrynichus speaks of a shellful of salt, and Dioscorides uses it as a small measure.[2] Lycophron uses it for the upper part of the skull, Polybius for the boss of a shield, Dioscorides for a small iron crucible, and Pollux for the socket of the eye and the kneecap.[2][3] Timon has it for a soup of lentils boiled in their pods.[2][1] Hesychius explains it as κοχλίας (kokhlías, “snail”).[7]

Medieval vernacular Greek kept it, also as κόγκος (kónkos).[8] In Modern Greek κόγχος (kónchos) lives on in the anatomical term for the eye socket, continuing the late ancient sense.[9][5]
