How Many Fingers and Knuckles on the Human Hand?

A couple of common questions I get are "Do we have ten fingers or eight fingers and two thumbs?" and "Does a hand have 4 knuckles or 14 knuckles?"

In each case, both answers are considered correct.

Technically it is a bit more accurate to say that there are 8 fingers and 2 thumbs.

The word "knuckle" uses the same distinction in its definition, so each hand has EITHER:
4 fingers and 4 knuckles, OR
5 fingers and 14 knuckles.

Could you please tell me why I have only 13 knuckles on each hand? My thumbs only have 1 knuckle and are aesthetically more attractive and work better as I have observed for many years comparing them to 14 knulers. Thank You James Harley Clark

actually all thumbs are fingers but not all fingers are thumbs so truly we have 10 fingers, 2 of which are thunbs
