Lutin (French)
A lutin is a type of hobgoblin in French folklore and fairy tales. Female lutins are called lutines. A lutin (varieties include the Nain Rouge or "red dwarf") plays a similar role in the folklore of Normandy to household spirits in England, Germany and Scandinavia.
Lutin is generally translated into English as: brownie, elf, fairy, gnome, goblin, hobgoblin, imp, leprechaun, pixie, puck, jetin or sprite. It sometimes takes the form of a horse saddled ready to ride, and in this shape is called Le Cheval Bayard. Lutins sometimes tangle people's or horses' hair into elf-locks.
