I like most forms of Elizabeth, including Elizaveta. I wouldn't say it's one of my absolute most favourite forms of the name, but still, I really do like Elizaveta. There's something very majestic about this form, more so than Elizabeth. It feels very elegant and serious, but also lively and zesty at the same time.
My name is Elizabeth, and I have a friend who is Russian. I asked her what my name would be in Russian, she told me 'Elizaveta', and I FELL IN LOVE! I want everyone to call me Elizaveta now!
I think this name sounds really pretty. It's also easy to come up with a nickname for it. I think Elizaveta's a great alternative to Elizabeth, because Elizaveta's much more prettier to say.
