What is the origin of vivify?
The English verb vivify comes from Old French vivifier, from Late Latin vīvificāre “to make alive, restore to life, quicken.” Vīvificāre breaks down easily to vīvus “alive,” from vīv(ere) “to live,” from a very widespread Proto-Indo-European root with many variants: gwei-, gwī-, gwi-, gwiyō- “live” (gw- usually becomes v- in Latin). The Proto-Indo-European forms gwīwos and gwiwos “alive, life” become vīvus in Latin, bivus in Oscan (an Italic language spoken in southern Italy), bíos in Greek (from bíwos, from gwiwos). The Proto-Indo-European adjective gwigwos become kwikwaz in Germanic and ultimately English quick (in the archaic sense “alive,” as in the phrase “the quick and the dead”). The suffix -fy comes from Middle English -fi(en), from Old French -fier, from Latin -ficāre, a combining form for verbs of doing or making, from the adjective suffix -ficus, from the verb facere “to do, make,” from the very complicated Proto-Indo-European root dhē-, dho- (and many other variants) “put, place,” the same source for English do. Vivify entered English in the 16th century.
