re: The Sun and the Moon
In german and dutch, there's indeed the neutral gender (and it's a constant pain at work); french and english have only masculin and feminin to cope with (every english speaking person always has a lot of difficulty with the genders in french;)
Welcome=Bienvenue (feminine).
You are welcome: Tu es le bienvenu (masculine).
Welcome to you: Bienvenue à toi (feminine).
Now, don't ask me why! I don't really know (sometimes welcome is a substantive (feminine) , sometimes it's an adjective (or is it an adverb) (masculine).
