Pronunciation:

lME digitalle, lME 16– digital. (Show Less)
Etymology:
< classical Latin digitālis measuring a finger's breadth, in post-classical Latin also of or relating to the finger (8th cent. in a British source) < digitus finger (see digit n.) + -ālis -al suffix1. With use as adjective compare Italian digitale of or relating to a finger (1575); French digital is first recorded much later (18th cent.). With digital number (see sense B. 1) compare post-classical Latin digitalis numerus (1619 or earlier), Italian numero digitale (1562 or earlier).
Classical Latin digitalis is apparently not used as a noun; post-classical Latin digitalis is attested denoting a finger-ring (11th cent.) and a thimble (see digitalis n.).
