Pronunciation

  • 5th-century BC Attic: /dé.os/[1]
  • 4th-century AD Koine: /ˈðe.os/[1]
  • 10th-century Byzantine: /ˈðe.os/[1]

Forms

δέος (déos) n (genitive δέους); third declension[1] Homeric genitive δείους; a rare genitive δέατος in Sophocles.[2]

Etymology

It is a verbal abstract noun of δείδω (deídō, “to fear”), from an older *δϝεῖος (*dweîos).[3][4] Wiktionary takes it as the s-stem noun from Proto-Indo-European *dwey- (“to fear”), the root that also gave δεινός (deinós).[1] The initial /dw/ is assured by Homeric metre, which still treats the word as beginning with two consonants (the genitive ⟨δείους⟩ is written for an older ⟨δϝέεος⟩).[5][2]

Beekes connects the verb with an Avestan word for “threat” and, with an s-extension, a Sanskrit verb meaning “to hate”, and perhaps with Latin dīrus (“fearful”).[3] Chantraine finds the closest match in the Armenian verb for “to fear”, a comparison that Kortlandt rejects, according to Beekes.[5][3] Chantraine and Beekes think the root may come in the end from the word for “two”, as in δίς (dís), fear being the state of a mind divided by doubt.[5][3]

Ancient writers derived it from δέω (déō, “to bind”), since fear binds (Chrysippus), or from the verb “to fear” itself (Philoxenus).[6]

Earliest recorded meaning

It is found from Homer on.[3][7] Its first occurrence in the Iliad (1.515) has the sense “cause for fear”: Thetis tells Zeus that he has nothing to fear in granting her request.[2][8] Elsewhere in Homer it is the fear that seizes warriors, the “pale fear” (χλωρὸν δέος) of the Iliad.[2][7]

Semantic evolution

In Classical Greek δέος was the ordinary word for fear and dread, used with a genitive of what is feared or with a clause “that something may happen”.[7][2] Thucydides and Lysias also use it of a means of inspiring fear, a threat, and the plural δέη is rare.[7][2] In Aeschylus it is also the awe felt before a superior power.[2]

Grammarians distinguished it from φόβος (phóbos): δέος is a lasting expectation of harm, φόβος the sudden fright of the moment.[9][2] In the New Testament it occurs once, in the Letter to the Hebrews, of the awe owed to God.[10]

It survives as Modern Greek δέος (déos), a learned word taken over from the ancient one.[11][12]

Timeline

  • Homer – The Iliad uses it of fear in battle and of a reason for fear.[2][7]
  • 5th century BC – Herodotus pairs it with φόβος (phóbos), and Thucydides uses it of a threat that inspires fear.[2][7][13]
  • 5th century BC – Aeschylus uses it of reverent awe.[2][13]
  • 1st–2nd century AD – The grammarian Ammonius sets it apart from phóbos as a longer-lasting fear.[9][2][13]
  • 1st century AD – The Letter to the Hebrews uses it of awe before God.[10]
  • Modern Greek – The word survives as a learned term.[11]

Meanings

Noun

  1. Fear, dread, alarm, sometimes with the genitive of what is feared.[2][7]
  2. A cause or reason for fear.[2][7]
  3. A means of inspiring fear; a threat.[7][2]
  4. Reverent awe, as before a god or a ruler.[2][10]

Usage notes

Ammonius distinguishes δέος, a lasting apprehension of harm, from φόβος, a sudden fright, and cites Herodotus pairing the two words.[9] Both words appear together in the orators as well.[2]
