A fairy tale, fairytale, wonder tale, magic tale, fairy story or Märchen is an instance of a folklore genre that takes the form of a short story. Such stories typically feature mythical entities such as dwarfs, dragons, elves, fairies, giants, gnomes, goblins, griffins, mermaids, talking animals, trolls, unicorns, or witches, and usually magic or enchantments. In most cultures, there is no clear line separating myth from folk or fairy tale; all these together form the literature of preliterate societies. Fairy tales may be distinguished from other folk narratives such as legends and explicit moral tales, including beast fables.
