I like it a lot but I still haven't really figured out what the original Greek pronunciation is. It's pronounced with three syllables in Greek for sure and I think it was tha-LY-ah, even though I'm not a 100% sure anymore.
The thing is, I don't like using this name and changing the pronunciation. Same with
Charis, I love it, but the English pronunciation only and not the Greek pronunciation. On the one hand I think it's fine to use an English pronunciation as people have done it with
Phoebe and
Zoe as well, on the other hand I find it disrespectful. Not with
Phoebe and
Zoe, probably because I'm used to them, but with
Thalia and
Charis. I don't know why.
But
Thalia pr. tahl-ya is just wrong to me. And I think people will always mispronounce it as they will use the Th-sound at the beginning.
Would you like
Talia or
Talya? They're Hebrew and I think they're pronounced the way you want them to be pronounced.
I wouldn't use
Thalia for the same reason why I wouldn't use
Alicia. Too many spellings, too many pronunciations. Also depending on where you live it's common (Australia).
I like
Blythe but I don't like
Thalia paired with it.
