Yeah! That's what the article I was reading was talking about - pidgin and creole - which was actually super informative since I've always just automatically associated creole with Louisiana creole and didn't realize it had an actual broader meaning!

I sadly don't have any grasp of linguistics or would I absolutely write the fic haha instead I am simply going to make vague references to the idea that Fëanor is being an asshole via linguistics and just avoid any and all details!
