Pronunciation

  • 5th-century BC Attic: /a.ěː.dɔː/[1]
  • 4th-century AD Koine: /aˈi.ðo/[1]
  • 10th-century Byzantine: /aˈi.ðo/[1]

Forms

ᾰ̓είδω (aeídō) [1] The contracted form ᾄδω (áidō) is the usual one in Attic, tragedy and Plato; ἀείδω is the Epic, lyric and Ionic form.[2][3]

Etymology

It is inherited from Proto-Hellenic *awéidō.[1] Beekes takes the ablaut of the family to point to Proto-Indo-European *h₂weid-, but no cognate outside Greek is known, and LIV records the root only with a question mark.[4][5] Within Greek it belongs with αὐδή (audḗ, “voice”) and perhaps ἀηδών (aēdṓn, “nightingale”).[4][6]

Wackernagel derived the present from a reduplicated aorist, comparable to ἔειπον (éeipon, “I said”);[6] LIV rejects this, and Frisk thinks a reduplicated aorist beside the noun should have had a different shape.[6][5] Harðarson reconstructed *h₂we-h₂ud-, which Beekes finds difficult because of the loss of the laryngeal.[4] Ancient grammarians explained it as an intensive prefix on εἴδω (eídō, “to know”), and Plutarch's grandfather Lamprias as built on /a/, the first sound a child makes.[7]

Earliest recorded meaning

The Iliad opens with it, asking the goddess to sing of the wrath of Achilles; in Homer it means to sing, or to sing of a subject.[2][8]

Semantic evolution

From Homer on it is to sing, or to celebrate someone or something in song, and in the passive to be sung or celebrated.[3][2] It is used of birds singing, of cocks crowing and of cicadas chirping, and in Hellenistic poetry of a stone that rings when it is struck and of a tree in the wind.[3]

Its derivatives ἀοιδός (aoidós, “singer”) and the contracted ᾠδή (ōidḗ, “song”) gave Greek its words for the poet-singer and the ode.[6] Modern Greek has the contracted verb as άδω (ádo).[9]

Timeline

  • Homer – The Iliad and the Odyssey use it for singing a song or a theme.[2][8]
  • Before the 6th century BC – Hesiod's Theogony opens with it.[8]
  • 6th–5th century BC – Pindar uses the passive for a sanctuary filled with song.[2][3]
  • 3rd century BC – Theocritus uses it of a stone ringing when struck.[3]
