Capri Uni, I must ask. Where did you get your information about the Brothers Grimm? All my life I have heard that they were philogists who collected the stories to study language shifts. And that, indeed, the stories they gathered provided the data for Grimm's Law of Indo-European Vowel Shifts. As a matter of fact, my copy of Grimm's 'original' tales rather rubs one's nose in it.
