[name_f]Ariana[/name_f] or [name_f]Arianna[/name_f]
I prefer [name_f]Ariana[/name_f], probably because it’s the more popular spelling, but not by much.
I like [name_f]Ariana[/name_f] better. Most -ana names I prefer with one n.
I prefer [name_f]Ariana[/name_f].
I also prefer [name_f]Ariana[/name_f]
[name_f]Ariana[/name_f] is my preference, though if you wanted to be clear that the pronunciation is AN-na rather than ARN-a then I would probably use [name_f]Arianna[/name_f].
It depends on how you want people to pronounce the last two syllables. If you want ar-ee-AHN-uh then use [name_f]Ariana[/name_f], if you want ar-ee-[name_f]ANN[/name_f]-uh thenuse [name_f]Arianna[/name_f].
[name_f]Ariana[/name_f] looks better in my opinion

I like [name_f]Ariana[/name_f].
