Pronunciation

  • 5th-century BC Attic: /kěu̯.tʰɔː/[1]
  • 4th-century AD Koine: /ˈceɸ.θo/[1]
  • 10th-century Byzantine: /ˈcef.θo/[1]

Forms

κεύθω (keúthō) [1] Also κευθάνω (Iliad 3.453) and κυνθάνει “hides” (Hesychius).[2][3]

Etymology

It is inherited from Proto-Hellenic *kéutʰō,[1] inherited from Proto-Indo-European *(s)kewdʰ- (“to cover, hide”).[4][1][2] The LIV sets it up as a full-grade thematic present of *kewdʰ- (“to hide”), with the root aorist κύθε (kúthe) and the perfect κέκευθα (kékeutha), and perhaps a nasal present in Hesychius' gloss κυνθάνω (kunthánō).[5] It notes that the Greek and Iranian forms would also fit *gʰewdʰ-, but that Proto-Germanic *huzdą (“treasure”) and Latin custōs (“guard”) clearly have *k-.[5]

Beekes, Frisk and Chantraine compare Old English hȳdan (the English word hide), and Sanskrit कुहर (kuhara, “cave”) and कुहू (kuhū́, “new moon”), the “hidden” moon.[4][3][2][1] The LIV, following Szemerényi, takes the Old English verb as derived from hȳd (“skin”) and keeps it apart.[5] Old Armenian սուզանեմ (suzanem, “to dive, hide”) would need an initial palatal *ḱ-, which does not fit the other words.[4][3] Beside these, several Greek forms with a final ⟨τ⟩, such as κύτος (kútos) and σκῦτος (skûtos), may belong to the same root.[4][2]

Earliest recorded meaning

It is a Homeric verb of covering and concealing: the Iliad uses it of a man covered by Hades (23.244) and of all that a city holds within it (22.118), and the Odyssey of the earth that covers a dead man (3.16), of a ship's cargo, and of hiding tears or thoughts.[6][7]

Semantic evolution

It remained a poetic verb.[7] Its favourite subject is the grave: in Aeschylus' Prometheus the earth does not hide a man even when he is dead, and the tragedians use it of the earth or an urn holding the dead.[7][8] The perfect could be intransitive, “to lie buried”.[2] It also means to keep something secret or hold back tears and laughter, to keep a person in the dark, and, more weakly, to harbour a plan or a hatred.[8] Thucydides and Aeschines have it in quoted verse.[8]

Its nouns κεῦθος (keûthos), κευθμών (keuthmṓn) and κευθμός (keuthmós) mean “hiding place, hollow, depths”, mostly in poetry.[3][2]
