Forms

αὖ (aû) adverb[1]

Etymology

It is inherited from Proto-Indo-European *h₂ew (“away, again”).[2][1] It matches Latin au- in aufugiō “flee away”, Lithuanian au- and the Old Church Slavonic prefix u- “away from”, and is probably related to a Sanskrit adverb meaning “down”.[2][3] Wiktionary compares Albanian a “or”.[1] It also forms adverbs and particles such as αὖτε (aûte), αὐτάρ (autár), αὖτις (aûtis) and αὖθις (aûthis), and the pronoun αὐτός (autós); compare auti and Latin aut and autem.[2][3][4]

Earliest recorded meaning

From Homer on it means “again, once more”, often with numerals (τρίτον αὖ “a third time”), and in a question it expresses impatience, as in “who now again…?” in the first book of the Iliad.[5][6][7]

Semantic evolution

From “again” it came to mean “further, moreover”, and, answering a clause with μέν (mén) or joined with δέ (dé), “on the other hand, in turn”.[5][6] Homer also used it for answering in speech, and it never stands at the beginning of its clause.[6][8] It is mainly poetic, but Plato and Xenophon use it too, with αὖθις (aûthis) and πάλιν (pálin).[3][6]

Timeline

  • Homer – The Iliad uses it for “again” and “in turn”.[5][6][7]
  • 6th–5th century BC – Aeschylus uses it with numerals in counting persons.[5][6]
  • 5th–4th century BC – Plato uses καὶ ἔτι γε αὖ “and moreover again”.[5][4]

Meanings

  2. Further, moreover, in addition.[5][6]
  3. In response, in reply.[6]
  4. On the other hand, but.[5][6]
  • αὖθις (aûthis)
  • αὐτάρ (autár)
  • αὖτε (aûte)
  • αὖτις (aûtis)
  • αὐτός (autós)

Usage notes

αὖ αὖ is also Aristophanes' imitation of a dog's bark, “bow-wow”, in the Wasps.[6][4]
