Minor alterations are made as a same narrative is repeated several times. As these tiny modifications accumulate over time, the tale will transform into a completely different one with only the same core plot components. The alterations were brought about via oral tradition when these fairy tales initially originated. There was no way to write down the stories then so they had to be told again and again for people to remember them. In addition to the main story, there are often subplots within folktales that tend to develop over time too. These can include: characters being challenged by other people or animals; conflicts arising between good and evil people; trials by magic or illusion; rescues by friends, family, or strangers; punishments for bad deeds; and happy endings. Folktales are popular because they deal with issues that concern everyone. In a world full of uncertainty, people need stories that provide clarity and hope. As well as entertainment, folktales serve as a guide to life's challenges and decisions, helping us to understand what happens after we die too! As they are passed on by word of mouth, folktales are always changing in some way. Even if you tell a story exactly how it started out, someone else may change something along the way. For example, a villain might become a hero or a victim could be saved at the last minute.
