A pot is a container that is usually made from earthenware or metal. Pots can be used for a great variety of things, and come in different shapes. Most pots are round but some are square, some have handles and some don't, some are narrow at the base and others are the same width the whole way up. Most pots have no lid but some do. Pots can be used to store things in, to cook food in, or to grow plants in. Pot is also a slang term for marijuana.
