A knitted jacket or jersey, often made of thick wool, that athletes wear before or after exercise. For warmth, a similar garment is used. A person who perspires heavily may need to replace his or her shirt more frequently than someone who is less affected by heat. The word "sweater" comes from the English language word "swathe," which means a bundle of something flexible like cotton or wool wrapped around something solid like wood or metal. The word was first used in 1765 to describe a piece of cloth used to swathe an injured body part to protect it while it healed. In modern usage, the term "sweater" refers to a garment that covers the torso, usually with arms' holes for wearing it. It may be simple or elaborate depending on the wearer's status or wealth. Women's sweaters are generally shorter and thinner than men's versions. Kids' sweaters tend to be smaller yet. Some examples of animals named after their color: red wolf, blue whale, yellow tiger. Other examples: cat, dog, cow, fish, lizard, bird.
