Word Origin & History
auspicious
1596 (implied in auspiciously), "of good omen," from L. auspicium "divination by observing the flight of birds," from auspex (gen. auspicis) "augur," lit. "one who takes signs from the flight of birds," from PIE *awi-spek- "observer of birds," from *awi- "bird" + *spek- "to see." Connection between birds and omens also is in Gk. oionos "bird of prey, bird of omen, omen," and ornis "bird," which also could mean "omen." Auspice (usually pl.) "influence exerted on behalf of someone or something" is from 1637.
