Folktales

I think a folktale is a story that has been told for many generations and every time something changes or more detail is added to a characters of the story. They are made up. At first they were not put in books but now you can get a folktale at your local library. Folktales were made to explain why things do the way they do or why things are what they are. In other words tell the unknown that can not be explained to people. This is what I think a folktale is.
