In Denmark and Sweden, the elves appear as beings distinct from the vetter, even though the border between them is diffuse. The insect-winged fairies in British folklore are often called älvor in modern Swedish or alfer in Danish, although the correct translation is feer . In a similar vein, the alf found in the fairy tale The Elf of the Rose by Danish author H. C. Andersen is so tiny that he can have a rose blossom for home, and has wings that reached from his shoulders to his feet . Yet, Andersen also wrote about elvere in The Elfin Hill. The elves in this story are more alike those of traditional Danish folklore, who were beautiful females, living in hills and boulders, capable of dancing a man to death. Like the huldra in Norway and Sweden, they are hollow when seen from the back.
The elves could be seen dancing over meadows, particularly at night and on misty mornings. They left a kind of circle where they had danced, which were called älvdanser (elf dances) or älvringar (elf circles), and to urinate in one was thought to cause venereal diseases. Typically, elf circles were fairy rings consisting of a ring of small mushrooms, but there was also another kind of elf circle:
In the first story of the Brothers Grimm fairy tale Die Wichtelmänner, the title protagonists are two naked mannequins, which help a shoemaker in his work. When he rewards their work with little clothes, they are so delighted, that they run away and are never seen again. Even though Wichtelmänner are akin to beings such as kobolds, dwarves and brownies, the tale has been translated into English as The Elves and the Shoemaker, and is echoed in J. K. Rowling's Harry Potter stories (see House-elf).
Successively, the word elf, as well as literary term fairy, evolved to a general denotation of various nature spirits like Puck, hobgoblins, Robin Goodfellow, the English and Scots brownie, the Northumbrian English hob and so forth. These terms, like their relatives in other European languages, are no longer clearly distinguished in popular folklore.
