This name sounds really nasal to me. When I was seven I liked the name, but now I absolutely hate it because I know someone named Lea that I am not particularly fond of.
I like this name, but there's an urban legend going around that there's a girl who spells it Le-a. On top of that, she supposedly pronounces it "Ledasha".
I'm surprised that as thorough a resource as "Behind the Name" only acknowledges ONE pronunciation for this name. This simple three-letter name can be pronounced several ways. The "German" way this site suggest would only be one--and I'm not even sure THAT's accurate. As someone who has German as a 2nd language, I'd say it's closer to LAY-a. Actress Lea Thompson, however, pronounces her name LEE-a (I believe). Whereas newswoman Lea Thompson pronounces it LEE. As a last name it's also monosyllabic (LEA & PERRIN).
My friend's name is Lea, and she pronounces it "Leah". Our teacher pronounces it "Leia" because he had a friend with the same name, and she pronounced it that way. So, to me, it seems that if you name your kid this, while pretty, it could get really annoying if people keep pronouncing it wrong.
This is my middle name, and my parents chose to pronounce it "lee." much like the word "flea" is pronounced "flee". My grandfather even had a rhyme to go with it. My name is Tonya and his nickname for me is "Tawny" and his little song that he used to sing to me went something like this, "Tawny Lea is a flea and she is really buggin' me."
