How to Write a Plural Suffix and Get a Single Noun?

News is a mass noun that has a meaning not related to plural or new in any standard way. Usually what would happen here is that with news, you would just say it's a single morphing and then you'd be done with it. But the issue with more pemic analysis is that, uh, meaning is supposed to be combinatorial. More themes are synchronic specifically. So the historical explanations just get thrown out anyway, so.
