what is wagon

A wagon, also spelled waggon, is a heavy four-wheeled vehicle pulled by draught animals or, on occasion, by humans. It is used for transporting goods, commodities, agricultural materials, supplies, and sometimes people. Wagons are distinguished from carts by having four wheels and are primarily used for carrying goods, unlike lighter four-wheeled vehicles designed for carrying people, such as carriages. They can be pulled by animals such as horses, mules, or oxen, and are used for various purposes, including agricultural activities and transportation of materials. In modern times, the term "station wagon" refers to an automotive body-style variant of a sedan with its roof extended rearward over a shared passenger/cargo volume, providing access at the back via a third or fifth door instead of a trunk/boot lid
