Ring finger

The ring finger, third finger, fourth finger, leech finger, or annulary is the fourth digit of the human hand, located between the middle finger and the little finger. Sometimes the term ring finger only refers to the fourth digit of a left-hand, so named for its traditional association with the wedding ring following instructions in the 1662 Book of Common Prayer, although other societies may not use this digit as the ring finger. Traditionally, a wedding ring was worn only by the bride or wife, but in recent times more men also wear a wedding ring. It is also the custom in some societies to wear an engagement ring on the ring finger. In anatomy, the ring finger is called digitus medicinalis, the fourth digit, digitus annularis, digitus quartus, or digitus IV. In Latin, the word anulus means "ring", digitus means "digit", and quartus means "fourth".
