(HQ 10.2:9):  In addition to qan "use the little finger, use the pinkie", there is another verb qan meaning "be old (not young)".  No doubt because of this resemblance, when one points at someone using the little finger, or when one remarks on this pointing, the pointer is making a comment on the age of the person being pointed to.
