The index finger or forefinger is the second digit of a human hand, located between the thumb and the middle finger. It is usually the most dexterous finger of a hand and is usually used to point to things (a direction, an object etc.), thus it is also called the pointer finger. It is also called the second finger, index, digitus secundus, or digitus II in anatomy.

Gestures

As mentioned above, the forefinger can be used for pointing. However, this gesture is considered rude in some countries (Brunei, for instance), and other gestures are used instead.

A lone index finger often is used to represent the number 1, or when held up, it can be an admonitory gesture.

During the Bosnian war , Orthodox Serbo-Bosnian troops raised two fingers in a victory sign (maybe related to Orthodox versions of the sign of the cross), Catholic Bosnian Croats raised three fingers (for Trinity) and Muslims raised the forefinger (after the strict monotheism of Islam).
