Forefinger → It is formed from "fore" (from Old English "foran", meaning before or in front of) and "finger" (from Old English "finger", meaning digit of the hand). The word "forefinger" refers to the finger that is in front, commonly known as the index finger.
Think of the word 'fore' meaning 'in front' — the forefinger is the finger that is in front, pointing the way.
