The index fingers, or the fingers next to the thumbs on each hand, used for pointing and precise manipulation.
From Old English 'fore' (front, forward) and 'finger.' Called 'fore' fingers because they are positioned forward and are the primary digits used for pointing and indicating direction.
Your forefinger is literally the 'forward finger'—it's the one that naturally extends when you point, and across cultures this finger is the symbol for indication and emphasis, making it linguistically accurate and physically intuitive.
