My best friend in called
Nicola. She gets called
Nikki by some of her college friends, well, most of them, but I always call her
Nicola since I've known her longer - before she started using the NN
Nikki. I think it's a nice name, I say it a lot! I HATE
Nicolette, it is so close to Nicorette, and I just dislike ette names.
Nicola looks more natural to me than
Nikola, but I like both. I quite like
Nicole as well and might use it as a mn as it is more versatile than
Nicola (I like a lot of -a names as first names)
