The story
Originally from Latin revīvificāt- (past participial stem of revīvificō (“revivify”)) + -ion. In later use, from revivify (see -fication). Compare later revivificate, Latin revīvificātiō (1567 in a British source), and French révivification. By surface analysis, re- (“again, anew”) + vivification (“giving of life”).
