Envenomate is formed from "en-" (meaning to cause to be) and "venom" (from Latin "venenum", meaning poison) and the suffix "-ate" (indicating to make or to cause). The word means to cause to become poisonous or to infuse with venom.
Think of 'causing to be' ('en-') and 'poison' ('venom') — that's how envenomate means to make something poisonous.
