Ahhh I understand :) To me that is not a problem because it's not a negative word or anything like that. I also doubt that most Spanish speakers would think of the word. At least I had a girl named
Nina in my class and she tried to tell our Spanish exchange students that her name meant girl in Spanish and they didn't get it because it sounds so different and then she had to write it down but even then it wasn't exactly the same, but they understood :P I once met a girl named Ninja pronounced NEEN-ya (like the word) but spelled like ninja :P that was odd to me personally.
