From Proto-Indo-European *nu (“now; well; and”) + diūs, reflecting the original nom.sg. of diēs (“day”) that was later remodelled on the accusative. The former component cognate to Latin num (“interrogative particle”), nunc (“now”), nūper (“lately, recently”); its length is uncertain, since the original short vowel of PIE appears to have undergone lengthening in numerous daughter languages. The original nominative also surfaces in me-dius-Fidius (“so help me God”, interjection) as well as in diurnus; whether it retained the length of the ū cannot be established.
- (Classical) IPA(key): /ˈnuː.di.uːs/, [ˈnuː.d̪i.uːs̠] or IPA(key): /ˈnu.di.us/, [ˈnʊ.d̪i.ʊs̠]
- (Ecclesiastical) IPA(key): /ˈnu.di.us/, [ˈnuː.d̪i.us]
- Note: the length of either vowel is uncertain - see Etymology.
