An earring is any kind of ring, stud, hoop, or dangling decoration that you clip on your earlobe or hook through a hole pierced in your ear. Many people wear two matching earrings, one in each lobe, although others have just one pierced ear and wear a single earring — and some have multiple piercings in which they can wear a variety of earrings. In the 18th century, an earring that dangled was called an ear-drop.
