Etymology: "Preemptive" is built from "preempt" plus the suffix "-ive," which turns a verb into an adjective meaning "tending to do or having the function of" the action named. "Preempt" itself came into English as a verb in the sense of acquiring something before others could, and "preemption" (the act of buying before others) was already in use before the adjective appeared. The suffix has a long ancestry. It passed from Latin "-ivus" into Old French "-if" and then into Middle English as "-yf," before settling into the modern "-ive" spelling. So the adjective is a relatively recent formation on an older verb-and-noun pair, with each piece carrying its own history into the word.
