Etymology: "Provoker" is a plain formation: the verb "provoke" with the agentive suffix "-er", meaning one who provokes. It came into English in Middle English, from the verb "provoke" joined to the suffix that turns a verb into a noun for the person or thing doing the action, as in "baker" or "lender". The verb itself came into English from Latin "provocare", meaning "to call forth" or "to challenge", built from "pro-" ("forth") and "vocare" ("to call"). The sense of calling someone out to a contest or fight is what carried over, so a provoker is literally someone who calls another out and stirs them up. The noun describes that person or agent directly, and its meaning of instigator of trouble follows naturally from the verb's sense of inciting a reaction.
