Etymology

[edit]

    Traditionally derived from Proto-Italic *digitos, 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 (though De Vaan is skeptical due to the presumed phonetic processes resulting in the change of a ḱ- to a ǵ- having no other examples in Latin).[1] Fingers were thus "pointers, indicators". The "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). The relation to Ancient Greek δᾰ́κτῠλος (dáktulos, finger) is unclear, particularly as the latter term's phonetics suggest a substrate origin.

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