Other forms: wagons
Anything can be a wagon, so long as it has wheels and can be pulled. Wagons are used for transporting goods, like grains from a farm, or your little sister who wants another ride around the block.
The origin of wagon is the German weg, meaning “move, carry.” You’ll see horse-drawn wagons carrying vegetables, or a wagon pulled by a tractor moving bales of hay into a barn. A paddywagon is slang for a police van that brings suspected criminals to the station. If you “fall off the wagon” that means you started drinking alcohol again after being sober for a while. And when you “hitch your wagon to a star,” you pursue a major goal.
