Is the giving tree a folktale?

"The Giving Tree," written by Shel Silverstein, is not a traditional folktale but rather a modern children's book that embodies folktale elements. It features themes of selflessness and sacrifice, akin to moral lessons found in folktales. However, it is an original story with a unique narrative style and illustrations, distinguishing it from classic folktales that are typically passed down through generations.
