Origin of vega
- Medieval Latin from Arabic (an-nasr) al-wāqi‘ the falling (eagle), Vega al- the wāqi‘ falling active participle of waqa‘a to fall wqʕ in Semitic roots
From American Heritage Dictionary of the English Language, 5th Edition
- 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).
- 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 Spanish vega (“meadow, fertile lowland"), which see for more information.
