Origin of Vega

  • From Medieval Latin, from Arabic واقع (wāqi"˜, falling), from the expression النسر الواقع (an-nasr al-wāqi"˜, falling eagle). The active participle واقع derives from the verb وقع (wáqa"˜a, to fall, drop, tumble, alight, pounce).

    From Wiktionary

  • 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

  • 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 Wiktionary
