So, world, I have discovered the most beautiful word in human language: Geiriaduriau.  It is Welsh.  It is pronounced something like "Gary-uh-deer-ee-eye." It means...Dictionaries.

So now the question is, does it go for my first born son or daughter?  If you leave off the pluralization it's just "Gary-uh-deer," which sounds pretty masculine, right?  And with a totally regular/boringly American nickname built right in! I think that's reasonable.
