@kensanata mine is also RPG related, but it's a long story...
So in 2nd ed. D&D, druids have their our druidic language. Playing a druid for a new campaign, and geek that I am, I decided to write my own language - just nouns and noun fragments, so I could name places/people/things. I based it on Welsh syllables, hence the vaguely Celtic feel.
"Gwmngilfen" was the name of my character's wolf companion, meaning "valiant protector". I rather liked it, and it's *never* taken :)
