Ok, so I love names of countries for girls, they are so beautiful. India, Ireland, and Italia are my favourites (I is a nice letter). This is a lovely name.
If you're going to name your daughter this, just do her a favor and keep her out of Europe. You'd better not have to move to Europe, and especially to Italy, of course, as this name sounds absolutely ludicrous in Europe. It means 'Italy' in numerous languages here, of course, but even if it didn't, well, it's the name of the country in Italy itself, and everyone knows that. If you like this name so much, name her Talia.
How could this name not be acceptable in Italy if the usage is stated as "Italian"? Read the description before commenting! And to say this name couldn't be used anywhere else in Europe is ridiculous. I live in Europe (Ireland, actually), and I think Italia is an awesome, beautiful name. It's perfectly acceptable, though I think it should only be used for Italian girls. Naming a child after a country you have never been to or have no connections to is silly.
I named my daughter Itali. I did so because I love what Itali is. It is love, music, harmony, food, music, cooking, dancing, loud, artful, surrounded by water, and shaped like a boot, I love boots. If I can instill any of these attributes, if not all, I would be one fulfilled lady.
I didn't think this was a real Italian name until I heard it on Francis Ford Coppola's late mother. It's a pretty name, but it does sound a little silly outside of Italy. It might lead to teasing, especially in America. Talia, which I prefer, might be a safer choice in English.
I like Italia. I'm surprised that people are suggesting Talia as a nickname or expressing their like for it. Talia, to me in Australia, is a very trashy name, equivalent to maybe Madyson or Destiny in the U.S.
I watch an anime called Hetalia the show is about personified countries really. Since my favorite character in the show is the girl version of personified Italy my mom thought it would be SO FUNNY to call me : Hetalia, Italia , or Talia. Although Italia has a nice sound to it in my opinion so does Talia so I don't mind. ; )
