Origin of VegaMedieval Latin ; from Arabic (ar nasr) al w?qi?, the falling (vulture)
Origin of VegaMedieval Latin, from Arabic (an-nasr) al-waqi‘, the falling (eagle), Vega : al-, the + waqi‘, falling, active participle of waqa‘a, to fall; see wq&ayin; in Semitic roots.
Perhaps chosen arbitrarily as a word beginning with "v" (for "volatility") that sounds as if it could be a Greek letter (like the related risk parameters "delta", "gamma" etc.)
From Medieval Latin, from Arabic ÙˆØ§Ù‚Ø¹ (wÄqi"˜, falling), from the expression Ø§Ù„Ù†Ø³Ø± Ø§Ù„ÙˆØ§Ù‚Ø¹ (an-nasr al-wÄqi"˜, falling eagle). The active participle ÙˆØ§Ù‚Ø¹ derives from the verb ÙˆÙ‚Ø¹ (wÃ¡qa"˜a, to fall, drop, tumble, alight, pounce).
- A surname.
- An automobile that was manufactured by Chevrolet Motor Division of General Motors Corporation from 1970 to 1977.
