Is rewriting an old fairy tale considered plagiarism?

Answer 1

It is only considered plagiarism when you do not give credit to the writer. If you are not able to find who wrote the fairytale, just be sure to right the original name before you change it if that is what you intend to do.

Hope this helps

Answer 2

No, rewriting an old fairy tale is not considered plagiarism as long as you are putting your own creative spin on it and not copying someone else's work verbatim. It is common for writers to draw inspiration from existing folklore and stories and create new versions or adaptations.
