Résumé
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 wedding rings in many societies, although not all 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".
The origin of the selection of the fourth digit as the ring finger is not definitively known. According to László A. Magyar, the names of the ring finger in many languages reflect an ancient belief that it is a magical finger. It is named after magic or rings, or called nameless (for example, in ).
In Japanese, it is called 薬指 (kusuri yubi, "medicine finger"), deriving its name from the fact that it was frequently used when taking traditional powdered medicine, as it was rarely used otherwise and hence was considered the cleanest of all.
In other languages such as Sanskrit, Finnish, and Russian, the ring finger is called "Anamika", "nimetön", and "Безымянный" (bezymianny, "nameless"), respectively.
In Semitic languages such as Arabic and Hebrew, the ring finger is called bansur (meaning "victory") and kmitsa (meaning "taking a handful"), respectively.

Before medical science discovered how the circulatory system functioned, people believed that a vein ran directly from the fourth digit on the left hand to the heart. Because of the hand–heart connection, they chose the descriptive name vena amoris, Latin for the vein of love, for this particular vein.
