Iuppiter Tonans ("Jupiter thundering") (late first century statue)

Alternative forms[edit]


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).
