Iuppiter

• Iūpiter, Jūpiter, Juppiter
• Iovis (“Jove”)

The nominative Iuppiter, for Iūpiter (with shift of the length from vowel to consonant per the "littera" rule), comes from the vocative combined with pater, and essentially meant "father Jove"; from Proto-Italic *djous patēr, from *djous (“day, sky”) + *patēr (“father”), from Proto-Indo-European *dyḗws (literally “the bright one”), root nomen agentis from *dyew- (“to be bright, day sky”), and *ph₂tḗr (“father”). Cognate with Umbrian 𐌉𐌖𐌐𐌀𐌕𐌄𐌓 (iupater), and in other branches of Indo-European Sanskrit द्यौष्पितृ (dyáuṣ-pitṛ́), Ancient Greek Ζεῦ πάτερ (Zeû páter, “o father Zeus”). Equivalent to diēs (cf. Iovis) + pater.

The oblique cases Iov-, Iovis continue the inflection of Proto-Indo-European *dyḗws. Cognates are Latin diēs (from the accusative case) and Ancient Greek Ζεύς (Zeús).
