A curtain is a piece of cloth used to block light, water, or cold air from entering a place (some curtains are better at blocking than others because of the type of fabric used).[1][2][3][4] Curtains are hung around showers to keep water off the floor around the shower. Curtains are also hung around windows to keep light from coming in. A curtain is raised and lowered during a play or other theatrical production. Curtains can come in many different colors and different types of fabric. It is also originally a French word.
Curtains can also be made from air.
