Definition

The index finger is located between the thumb and the middle finger. This finger is used by people to point at or indicate a direction or object. At school, raising one's finger high in the air signals the wish to speak. This finger is also used to press the button calling for an elevator, or to mime writing with one's fingers. The index finger literally means the "pointing finger", and it represents one of the five fingers of the hand, along with the thumb, the middle finger, the ring finger, and the little finger.
