Elaina means "bright light" and you can bet a person who carries it will be a shiny beautiful soul! It's like "Elaine" bit a little fancier somehow. And...maybe I'm a little biased here but 'Eliana" is definitely not prettier! :)
Absolutely phenomenal name, people named Elaina are the coolest around and I have only met 1 Elaina but she is a cool one. The only issues is that she always pees on the carpet, still wonderful though... I just really like unpissed carpet.
