"beget, generate, engender (children)," 1530s, a back-formation from procreation or else from Latin procreatus, past participle of procreare "bring forth" (offspring), "beget, generate, produce," from pro "forth" (see pro-) + creare "create" (from PIE root *ker- (2) "to grow"). Related: Procreated; procreating.
word-forming element making adjectives from verbs, meaning "pertaining to, tending to; doing, serving to do," in some cases from Old French -if, but usually directly from Latin adjectival suffix -ivus (source also of Italian and Spanish -ivo). In some words borrowed from French at an early date it has been reduced to -y (as in hasty, tardy).
