The term 'Mitten' is a type of GLOVE that covers the entire hand and usually has a separate compartment for each finger. It is typically made of wool or other thick material to keep the hands warm in cold weather. The term 'GLOVE' is also a type of hand covering, but it only covers the palm and fingers, leaving the thumb exposed. Gloves are usually made of thinner material than mittens and are used to protect the hands from dirt or other hazards.
