I much prefer
Sofia over
Sophia... I also like
Sona (
Sonia) as a full name or as a nickname.
Sonina is nms, but Sofinka (as a nn, of course!) Is really pretty.
Sofie is adorable as well! The only problem with all the Sofie-names is, thet they are really popular. And so graceful name as
Sofia doesn't fit all the bearers...
I love
Sofia especially as a mn (but also as a fn!).
My favourite combo is international
Anna Sofia.
And I hate
Sofia pron. SO-fee-ah, as many Finns do :(. This pronouciation destroys the beauty of this name.
