Well, in the story of Snow White and the Seven Dwarfs, the dwarfs are named quite interestingly. Doc is like the leader, often seen as the smartest. Grumpy is always in a bit of a bad mood. Happy is, as his name implies, always cheerful. Sleepy is constantly tired. Bashful is shy. Sneezy has a sneezing problem. And Dopey is the silly one. Their names really help to bring out their distinct personalities in the story.
In the traditional Snow White story, the dwarfs are often named Doc, Grumpy, Happy, Sleepy, Bashful, Sneezy, and Dopey. Snow White doesn't have a different 'hidden' name in the original story, she is simply Snow White.
Most likely not. The names of Snow White and the dwarfs were created by the storytellers for the purpose of the fairy tale. They are fictional names to bring the characters to life.
The 7 dwarfs are not based on real people. They are a product of the author's imagination. They were designed to have distinct personalities and appearances to make the story more interesting. For instance, their names reflect their different traits, and they live in a make - believe cottage in the forest. There's no evidence to suggest they are modeled after real individuals.
