contraceptive

"birth control, prevention of conception in the womb," coined 1886 from Latin contra "against" (see contra (prep., adv.)) + ending from conception.

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).
