A folktale is an old story that's been told again and again, often for generations. If you're interested in learning more about your heritage, you might read some folktales from the country in which your great-great-grandparents grew up.
Folktales are stories in the oral tradition, or tales that people tell each other out loud, rather than stories in written form. They're closely related to many storytelling traditions, including fables, myths, and fairy tales. Every human society has its own folktales; these well-known stories, handed down between generations, are an important way of passing along knowledge, information, and history.
