Pronunciation

  • IPA (Classical): [ˈa.wɪs][1]
  • IPA (Ecclesiastical): [ˈaː.vis][1]

Forms

avis f (genitive avis); third declension[1] The ablative singular is avī or ave, the former usual in the language of religion.[2][3]

Etymology

It is inherited from Proto-Italic *awi- (“bird”), inherited from Proto-Indo-European *h₂éwis (“bird”), an i-stem; de Vaan argues against the view, current since Schindler, that it was a root noun, and connects it with ōvum “egg” as a vr̥ddhi derivative.[4][1][5] Cognate with Umbrian avif, with Sanskrit वि (ví-, “bird”) and Avestan vaii- (“bird”), Ancient Greek αἰετός (aietós, “eagle”) from *h₂ewi-eto-, Armenian հաւ (haw, “bird”) and the Brittonic word for “duck”, Middle Welsh hwyat.[4][1][2] The compounds auspex “bird-watcher, augur” and auceps “bird-catcher” contain it.[4] Festus derived it from adventus, and Isidore of Seville explained that birds have no fixed roads but run through trackless places (avia).[5]

Earliest recorded meaning

It is found from Naevius onwards,[4] who has Anchises observe a bird in the sacred precinct, and Ennius has Remus watching alone for a favourable bird.[2]

Semantic evolution

Besides the bird as a creature, caught or served at table, it meant poultry (aves cohortales), and avis alba or avis rara, a white or rare bird, was a marvel.[2][6] Many birds were named by an epithet: avis Afra the guinea fowl, avis Iunonis the peacock, avis Romana the eagle.[2]

In augury it was the bird observed as an omen and hence the omen itself, avi sinistra, “with a bad omen”, or secundis avibus, “with good omens”.[2][6] Poets applied it to the constellations of the Swan, the Crow and the Eagle, and Varro once calls bees aves.[2][3] Medieval texts use it especially of birds of prey and game birds, and of the royal birds reserved for the king;[7] Köbler notes avis regia for the falcon.[8] It survives as Spanish and Portuguese ave.[1]
