Pronunciation

  • IPA (Classical): [ˈdɪ.ɡɪ.tʊs][1]
  • IPA (Ecclesiastical): [ˈdiː.d͡ʒi.tus][1]

Forms

digitus m (genitive digitī); second declension[1]

Etymology

The origin is uncertain.[2] A link with dīcō “to say, show”, the finger as “pointer”, is attractive and often assumed, from Proto-Indo-European *deyǵ- (“to show”) beside Proto-Indo-European *deyḱ-, but de Vaan notes that the change of /k/ to /g/ would be unparalleled in Latin.[2][1][3][4] The Thesaurus also mentions comparisons with Old High German zēha (“toe”) and Gothic 𐍄𐌰𐌹𐌺𐌽𐍃 (taikns, “sign”).[5]

Earliest recorded meaning

Naevius uses it.[2] Köbler dates Naevius c. 235–200 BC.[6]

Semantic evolution

It was a finger, digitus pollex the thumb and digitus index the forefinger, and a toe.[3][4] Cicero speaks of touching something with the tips of the fingers and of touching the sky with a finger.[7] As a measure it was a finger's breadth, a sixteenth of a Roman foot.[3][1] It was also the tip of a twig.[3][1]

In medieval Latin it was used in counting on the fingers and in mathematics.[8][9] It survives as Italian dito, Spanish dedo, Portuguese dedo and Romanian deget.[1] English digit is recorded in the late 14th century as a numeral below ten, since such numbers were counted on the fingers.[10]
