Iuppiter Tonans (late first century statue)

Alternative formsEdit


PIE root

The nominative Iuppiter, for Iūpiter (with shift of the length from vowel to consonant per the "littera" rule), comes from a vocative combined with pater, and essentially meant "father Jove": Proto-Italic *djous patēr, from *djous ‎(day, sky) + *patēr ‎(father), from Proto-Indo-European *dyḗws ‎(lit. the bright one), root nomen agentis from *dyew- ‎(to be bright, day sky). It is cognate with Umbrian 𐌉𐌖𐌐𐌀𐌕𐌄𐌓 ‎(iupater), and in other Indo-European branches also Sanskrit द्यौष्पितृ ‎(dyauṣ-pitṛ), Ancient Greek Ζεῦ πάτερ ‎(Zeû páter, o father Zeus).

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).
