Diiovis

• Diovis, Dijovis
• Iovis, Jovis (Classical Latin, Late Latin)

Old Latin from Proto-Italic *djous, *djowes (“day, sky; Jove”) from Proto-Indo-European *dyḗws (“sky god”, literally “the bright one”) from *dyew- (“to be bright, day sky”). Combining the root with the title Pater (“Father”) forms Old Latin Diēspiter (“Jupiter”, literally “Father Jove”) whence the nominative and vocative of later forms of Diiovis are derived by analogous formation (cf. Iuppiter, Iovis). Related to diēs, dīvus, dīus, Diāna, deus. Cognates include Doric Greek Δεύς (Deús), Attic Greek Ζεύς (Zeús)—the Greek god to whom Roman Diiovis is later equated.
