Thanks, I wondered that--when I first read it ("read" in the sense of sounding it out and looking for words I might know), 'duenos' reminded me of the Spanish for "owner". I was puzzled to find it translated "the good (man)" instead, but this explains it. I guess dw --> b makes some sense, too. So why did 'duo' not become bo?
