The Aarne-Thompson-Uther Classification System

The Aarne-Thompson-Uther (ATU) Classification System is a method used by folklorists to categorize and organize fairy tales, legends, and folklore stories based on common themes and narrative patterns. It groups stories with similar plots, characters, or motifs into numbered types, making it easier to study how stories evolve across cultures and regions. For example, stories with a "cunning hero" or "stepsisters" are classified under specific ATU numbers. This system helps scholars analyze storytelling traditions systematically, revealing connections and shared cultural elements worldwide.
