What is the proper way to write a fairytale?

To write a fairytale, start with a clear moral lesson or theme that guides the narrative. Incorporate classic elements such as magical beings, a hero or heroine, and a conflict that leads to a transformative journey. Use vivid imagery and simple, engaging language to evoke a sense of wonder, and conclude with a resolution that reinforces the story's message. Remember to maintain a whimsical tone and embrace the fantastical elements that make fairytales enchanting.
