Pronunciation

  • IPA (5th-century BC Attic): /kŷː.dos/[1]
  • IPA (4th-century AD Koine): /ˈcy.ðos/[1]
  • IPA (10th-century Byzantine): /ˈcy.ðos/[1]

Forms

κῦδος (kûdos) n (genitive κῡ́δους or κῡ́δεος); third declension[1]

Etymology

It is probably inherited from Proto-Indo-European *kewd-s- (“miraculous power”), as Beekes reconstructs it, comparing Proto-Slavic *čudo (“wonder, miracle”), whose relatives in Old Russian have overtones of sorcery.[2][1] The Greek word names the radiant power of the gods, or the power they confer, as Benveniste put it.[2] Greek ⟨ῡ⟩ in κῦδος replaced the full grade ⟨*eu⟩ of the root.[2]

Frisk, after older scholars, linked the Slavic word with a verb for “to hear, perceive”, Old Church Slavonic чоути (čuti), and so explained κῦδος as “what is heard of”, like κλέος (kléos).[3] Wiktionary similarly connects it with Proto-Indo-European *(s)kewh₁- (“to perceive”) and κοέω (koéō).[3][1][4] Beekes rejects this, as that root has no final d.[2]

Earliest recorded meaning

In the Iliad it is first the outward splendour of a god, in the phrase “exulting in his glory”, and then the glory of victory that a god gives to one side in battle.[5][6][7]

Semantic evolution

In Homer κῦδος is the glory of warriors and kings, often given by Zeus, and the triumph of victory; a person can be the glory of a people, as Odysseus and Nestor are “the great glory of the Achaeans”.[5][7][6] It remained a poetic word, found in lyric, in Herodotus and in Aeschylus, but not in Sophocles, Euripides or Attic prose.[7] Aristophanes uses it only in a mock-epic line.[7][6]

English kudos was taken from it in 1799, probably in university slang; the back-formation kudo is from the 1930s.[4]
