Latin

digitus manūs (digit of the hand)

Etymology

From Proto-Indo-European *deyǵ- ‎(“to show, point out, pronounce solemnly”), variant of the root *deyḱ- that also gave Latin dīcō ‎(“I say, speak talk”) and English toe. Fingers were thus "pointers, indicators". Digit sense comes from the fact that they were used for counting up to ten.

Indo-European cognates include Sanskrit दिशति ‎(diśáti, “to show, point out”), Ancient Greek δείκνυμι ‎(deíknumi, “to show”), δίκη ‎(díkē, “manner, custom”), Old English tǣċan ‎(“to show, point out”) (English teach) and tācen (English token).

Compare similar semantic shift in English in the cognate word teacher ‎(“forefinger, index finger”).
