WHAT IS THE ORIGIN OF EVANESCENT?
The adjective evanescent, “vanishing, fading,” comes via the French adjective évanescent, from Latin ēvānēscēns (inflectional stem ēvānēscent-), the present participle of the verb ēvānēscere “to disappear, vanish, fade away,” whose root word is the adjective vānus “empty, hollow, illusory,” source of English vain (via Old French). Ēvānēscere is a compound of the preposition and prefix ex-, ē- “out, out of, utterly, completely” and the verb vānēscere “to melt into nothing, vanish.” Ēvānēscere becomes esvanir, evanir in Old French, with a present stem esvaniss-, evaniss-, the source of Middle English vanis(s)hen, “to disappear, disappear suddenly,” English vanish. Evanescent entered English in the early 18th century.

Every gesture is sharp but evanescent, vanishing as quickly as it takes shape. - SARAH L. KAUFMAN, "IN PAIN AND RAGE, A PROTESTER APPROACHED POLICE. AND THEN HE DANCED," WASHINGTON POST, JUNE, 6, 2020
