Pronunciation

  • Classical: [ˈau̯s.pɪ.kɔr][1]
  • Ecclesiastical: [ˈau̯s.pi.kor][1]

Forms

auspicor (present infinitive auspicārī, perfect active auspicātus sum); first conjugation, deponent[1] An active auspicō is found in early Latin.[2][3][4] Claudius Quadrigarius spells it osp-.[2]

Etymology

It is from Latin auspex (“one who watches birds for omens”) + -or, as auguror is from augur.[2][3][4] De Vaan derives auspex from ⟨*au̯i-speks⟩, a compound of avis (“bird”), from Proto-Indo-European *h₂eu-i- (“bird”), and the root of speciō (“to look”), from Proto-Indo-European *speḱ- (“who sees”).[5]

Earliest recorded meaning

Naevius has the active form: a praetor arrives and takes favourable auspices.[3] Plautus also uses the active, as in the Stichus, where someone asks whether he has taken a weasel for an omen in a matter of life and death.[2][3]

Semantic evolution

It means to take the auspices: Cicero tells how Gracchus forgot to take them when he crossed the city boundary, and speaks of taking them by the tripudium;[3] Livy writes that the birds did not approve when Fabius took the auspices.[3] Varro has dē caelō auspicārī, from signs in the sky.[2] It is also to make a ceremonial beginning: Varro says the priest of Jupiter inaugurates the vintage.[2] After Augustus it often means simply to begin, to make a start for luck's sake: Columella says people begin every kind of work on the first of January for the omen, Seneca used to make a start by jumping into the Aqua Virgo, and Suetonius has Nero begin his jurisdiction and his singing.[3] Pliny the Elder says man begins life with punishments.[3] Apuleius has the active in the sense "to portend": yesterday's rain was an omen of their tears.[2] The older active auspicō is found in Naevius, Caecilius, Atta and Plautus.[3][4] Stelten gives "begin" for Church Latin.[6]
