A glove is a piece of clothing that you wear on your hand, to protect it or keep it warm. Most people wear a pair of gloves, unless — of course — they are imitating Michael Jackson.
Cold-weather gloves are soft and warm, made from fabrics like wool, polar fleece, or leather. There are also gloves that protect the skin on your hands while you're cleaning, using chemicals, or washing dishes; and gloves that prevent the spreading of germs, worn by food handlers and health care workers. Athletes sometimes wear gloves as well, like boxing gloves or the gloves worn by hockey goalies.
