Until now I've always read
Jadzia as a three syllable name, and I don't think it's because of
DS9.
Jadzia just genuinely looked like a three syllable name to me. *Blushes* But upon reading your post I went back to Wikipedia...
And read there that "dz" together produces the
ds sound, as in the English word "woods". So, yes,
Jadzia would be a two syllable name.
I shall go slink away now in embarrassment...
