Origin: 1535–45; alteration (with -fy for -ficate) of late Middle English vivificate < Latin vīvificātus (past participle of vīvificāre). See vivi-, -ficate
1590s, from O.Fr. vivifier (12c.), from L.L. vivificare "make alive, restore to life," from vivificus "enlivening," from L. vivus "alive" (see vivid) + root of facere "to make" (see factitious). Vivificate in same sense is recorded from early 15c.
