The word "plane" originates from the Latin planus, meaning "flat" or "level." It entered English via Old French plane (a tool for smoothing wood) and later expanded to describe geometric flat surfaces and aircraft (shortened from "aeroplane," itself derived from Greek aero- (air) + planos (wandering, but later associated with flatness in flight). The silent "e" is a vestige of Middle English spelling conventions.
