Exterminator → It is formed from "ex-" (meaning out of or away) and "terminare" (meaning to limit or end). The word "exterminator" refers to someone who eliminates or drives out pests or unwanted entities, effectively ending their presence.
Think of someone who drives pests 'out' ('ex-') and 'ends' ('terminare') their existence — that's why an exterminator is someone who eliminates unwanted creatures.
