οὖρος1 fair wind

Confidence

Formation

From
Proto-Indo-European *h₃er-
Ultimate origin

Pronunciation

  • 5th-century BC Attic: /ûː.ros/[1]
  • 4th-century AD Koine: /ˈu.ros/[1]
  • 10th-century Byzantine: /ˈu.ros/[1]

Forms

οὖρος (oûros) m (genitive οὔρου); second declension[1]

Etymology

The fair wind is perhaps from Proto-Indo-European *h₃er- (“to rise, set in motion”), extended as *h₃er-u-, through a pre-form *ὄρϝος (*órwos);[2][1] this is the root of ὄρνυμαι (órnumai) “to rise, rush” and ὀρούω (oroúō) “to rush forward”.[2][3][4] Frisk gives the connection as a suggestion of Prellwitz.[3] If it is right, Attic οὔριος (oúrios) must be a Homeric or Ionic form.[2][3]

Earliest recorded meaning

In the Iliad and the Odyssey it is a favouring breeze sent by a god to speed a ship, such as the wind Apollo sends the Achaeans; once in the Iliad it is simply a wind.[5][6]

Semantic evolution

Pindar and the tragedians used it figuratively: a fair wind of song, a good moment for action, or what speeds someone out of trouble.[7] From it came οὔριος (oúrios) “with a fair wind, favourable”, an epithet of Zeus, the noun οὐρία (ouría), and the verbs οὐρίζω (ourízō) and ἐπουρίζω (epourízō) “to speed with a fair wind”.[2][3]

Modern Greek uses the learned adjective Modern Greek ούριος (oúrios) in the phrase “fair wind”, literally and of favourable conditions.[8][4]

Timeline

  • Homer – The Iliad uses it for the fair wind Apollo sends.[5][6]
  • 6th–5th century BC – Pindar uses it for the fair wind of song.[7][9]
  • 6th–5th century BC – Aeschylus uses the phrase “with the wind”.[10][9]
  • Modern Greek – The learned adjective Modern Greek ούριος (oúrios) continues the derivative οὔριος (oúrios).[8][4]

  1. A fair wind, a favouring breeze for sailing.[6][7][5]

Inherited from

Ultimate origin

Pronunciation

  • 5th-century BC Attic: /ûː.ros/[1]
  • 4th-century AD Koine: /ˈu.ros/[1]
  • 10th-century Byzantine: /ˈu.ros/[1]

Forms

οὖρος (oûros) m (genitive οὔρου); second declension[1] Mycenaean wo-wo is read /worwos/.[2] Cretan has the verb οὐρεύω (oureúō) “to guard”.[2][3]

Etymology

The guardian is inherited from Proto-Indo-European *wer- (“to observe, watch”), from a pre-form *ϝόρϝος (*wórwos), which Beekes finds in Mycenaean Greek wo-wo.[2][1] It can hardly be separated from ὁράω (horáō) “to see”.[2][3][7] Wiktionary mentions another theory, from Proto-Indo-European *sorwos (“guardian”), comparing Latin servus.[1]

Earliest recorded meaning

In Homer it is almost only used in the phrase “guardian of the Achaeans”, an epithet of Nestor; in the Odyssey Telemachus speaks of a guardian left over his property.[2][6][5][7]

Semantic evolution

Pindar called Achilles the guardian of the Aeacids, and Apollonius of Rhodes used it of Talos, the bronze guardian of Crete.[6][7] The compound ἐπίουρος (epíouros) “guardian, ruler” and Cretan οὐρεύω (oureúō) “to guard”, with οὐρεῖα (oureîa) “fortress”, belong here.[2][3]

Timeline

  • Homer – The Iliad calls Nestor “guardian of the Achaeans”.[5][6]
  • 6th–5th century BC – Pindar uses it of Achilles.[6][7][9]
  • 3rd century BC – Apollonius of Rhodes uses it of Talos, guardian of Crete.[7][9]

Meanings

Noun

  1. A watcher, guardian, protector.[6][7][5]

Word family

  • ἐπίουρος (epíouros)
  • οὐρεύω (oureúō)
  • ὄρνυμαι (órnumai)
  • ὁράω (horáō)

Usage notes

Three more words share this spelling.[6][1] It is the Ionic form of ὅρος (hóros) “boundary” (LSJ οὖρος C),[6][7][11] and the Epic and lyric form of ὄρος (óros) “mountain”.[1][5][11] In an epigram attributed to Hadrian it names the aurochs (LSJ οὖρος D), from Latin ūrus.[6][1][10]
