Equivalent to the root of dīvus (“god”) + -āna. The feminine dīva (“goddess”) derived from deiva, from Proto-Italic *deiwā from Proto-Indo-European *deywós from *dyew- (“heaven, day sky; to shine”). Roughly akin to *deiwā + Proto-Indo-European *-néh₂. Later form Dīāna derived by syncope. Compare early Ancient Greek Διϝωνᾱ (Diwōnā) and Διϝωνη (Diwōnē), syncopated to Doric Greek Διώνᾱ (Diṓnā) and Attic Greek Διώνη (Diṓnē).
Dīvāna f (genitive Dīvānae); first declension
