My 3 year old is Juliette. French spelling. I feel that the Shakespeare spelling emphasizes the JU syllable - JUUU-liet. Whereas my spelling emphasizes the ETTE. Julie-ETTE. That's the main difference. I do NOT say "Ette-UH" like French.
I love the name! Have only met 1 other, and she's 6, and spelled Juliet. People comment all the time they love the name. It's feminine and not trendy or too common.
