By the way, brainiac, the most common form in Canada is tuque, and that is the French-Canadian form. Now i'll have the opportunity to be amused by your attempt to claim that the French in Canada have no right to spell or pronounce the word differently than you have decreed from your seat on high.
You're getting way off topic, laddie. Of course there are different spellings. There are almost certainly different pronunciations as French is a different language than English.
But that doesn't change the fact that you're ill-informed, Set. If your idea had any merit, and remember, you're the one who has made the claim that a toque can be called a toboggan, then it seems clear that you'd be able to find a reference to it somewhere.
But if instead of finding out the truth, you'd rather just be cantankerous, by all means, be my guest. That has always seemed to be your stance with repect to language issues. Actually a lot of issues.
