How can you have Florin, but not Guilder? Or is there a Florin other than the one in The Princess Bride?

Hors d’œuvre was mine. Even though I had heard the word pronounced many times, I never made the connection. Always pronounced it "whores de vores" in my head. Was in my 20's when I figured it out. Myriad always gets me too, even though I know the right pronunciation, when I read it always comes out "my-raid."
