Topic on Category talk:Trope Workshop

I know that this site has copyright policies that don't allow straight-up copypastes from TV Tropes. Not complaining about that since I whole-heartedly agree with the rules, but how does this work in terms of tropes themselves? I've been wanting to make pages for tropes we currently aren't covering like Moth Menace, Wicked Wasps, and Not-So-Well-Intentioned Extremist, but do the copyright policies disallow creation of these tropes? I just want a clear understanding before going through with what I've considered to be a pretty big project.
