I've a question about copyrighting. When I first started working on my book I thought up a name for the setting. Then a while later I found another book with a similar name for its setting. It's not a made up name or anything, it's just a regular word name. I've been trying to come up with something else, but I can't think of anything I like as much. If it was the same name, especially something made up, I wouldn't even be wondering about this, but is it still considered copying to use a similar name? Thank you.
