1. A lifting device consisting of a platform or cage that is raised and lowered mechanically in a vertical shaft in order to move people from one floor to another in a building: Most department stores have elevators that allow shoppers to get from the main level to any of the other areas above it in a very short time without the need to walk up the stairs.
2. A storehouse for grain, equipped with a mechanism for taking in, lifting, and discharging the grain: While on their trip through the flatlands, Ted and his family could see many elevators or silos being used for keeping wheat, barley, or corn dry.
3. A machine with scoops or similar devices for hoisting something to a higher level: From the distance, the children watched the grain elevators unloading carloads of corn in the trains, one after the other.
4. A hinged flap, either of a pair on the rear portion of the horizontal stabilizing surface or tailplane of an aircraft, used to control the aircraft's up-and-down movement: The elevators on the wings of the planes are essential for their successful takeoffs and landings.
5. On an aircraft carrier, a mechanized platform that transports aircraft from a below-the-deck hangar up to the flight deck and vice versa: Several airplanes were being elevated during the day so the pilots could get more knowledge and skills.
6. A muscle that contracts to lift a part of the body: The jaw elevators raise the lower jaw to the upper jaw while chewing, making it possible for people to eat!

A tall building for storing grain: The farmer took his harvested wheat to the grain elevator in order to keep it dry during the winter months.
