Okay, I've got a good question. I hope it has not already been asked, because then I will feel foolish.
What exactly is the meaning behind the various "prefixes" (for lack of a more accurate term) for the royalty's name? Such as Lelouch
Vi Britannia, or the others:
Charles
Di Britannia
Schneizel
El Britannia
Cornelia
Li Britannia
If anyone knows what they mean and why they are different, I would be grateful.
