I clicked on this thread for the simple reason that I have no clue as to what "dunsky" means. Hold on, I'll go a little low-tech and check out the Shorter Oxford dictionary that's gathering dust on my shelves at the moment.
[Added -] Nope, no help from there I'm afraid.
However, I think this could have something to do with the word "dunce", that means "stupid".
YoHf, how would an Italian pronounce the word "dunce"? In English, it's simply pronounced "duns".
Getting back here in a few minutes...
