Overrun → It is formed from "over-" (meaning excessively or beyond) and "run" (from Old English "rinnan", meaning to flow or move). The word "overrun" means to flow or move excessively beyond a limit or boundary.
Think of something that moves or flows 'beyond' ('over-') its intended path — that's why overrun means to exceed limits.
