The Marmota monax, woodchuck, groundhog (hamburger?), whistle pig, or marmot got me to wondering where the chuck in woodchuck came from. Evidently, from some folk etymologizing on an Algonquian word, (cf. Narraganset ockqutchaun 'woodchuck'). The word in question is not known. (So, say M-W and A-H, at least.) In German, they're called a Murmeltier 'mutter animal' (cf. Mermelvokale 'schwa'. And Murmel is a marble. How about that marmota? Perhaps from OFr marmotter 'to mumble' from murmuro 'mutter, grumble'. Anyway, I enjoyed the movie, but then chacun a son gout.
