Dionisia
dee-oh-NISS-ee-uh
A feminine form tied to Dionysus, carrying the sense of devotion to the god of wine and revelry.
Meaning
The name ultimately comes from Greek Dionysos, the name of the god Dionysus. In the excerpted sources, Dionisia is treated as a feminine form of that name and as an English usage; the older books also group it with related forms like Denise, Donnet, Dennet, and Diot. The core etymological link is therefore to Dionysus rather than to an independent native meaning.
