Archetypes are universal symbols or themes that appear across different cultures and stories. They represent fundamental human experiences and emotions, such as the hero, the mentor, or the trickster. These characters and ideas help us understand complex narratives by providing familiar patterns that resonate with our own lives. In literature and psychology, archetypes serve as a framework for storytelling and character development. For example, the hero's journey is a common archetype where a character goes on an adventure, faces challenges, and ultimately transforms. By recognizing these archetypes, we can better appreciate the stories we encounter and the lessons they convey.
