truck
A large motor vehicle used to carry heavy loads.
A truck is a large, powerful motor vehicle designed to carry heavy loads. Unlike cars, which are built mainly for passengers, trucks are built for work: hauling construction materials, delivering furniture, transporting food to grocery stores, or moving equipment from place to place. Trucks have strong engines and sturdy frames that let them pull trailers weighing thousands of pounds.
The back of a truck usually has an open bed or an enclosed cargo area. Pickup trucks, popular with families and workers alike, have an open bed where you can load lumber, sports equipment, or camping gear. Bigger trucks, like eighteen-wheelers (called that because they have eighteen wheels total), haul enormous loads across the country on highways. Everything from smartphones to strawberries probably arrived at its destination on a truck.
People also use truck as a verb meaning to transport something, though this usage is less common today. You might read in an old book about farmers trucking their produce to market.
The phrase “keep on trucking” means to keep going despite difficulties, like a dependable truck that keeps running mile after mile. When someone says they have no truck with something, they mean they want nothing to do with it.
