Wikipedia and other sources tend to use “the Fediverse”, but I’ve also seen just “Fediverse”. From what I know, it depends on whether the term is a proper name or just the name of a unique thing. Could someone please explain how do you think the term should be properly named and why?
Technically “kingdom” isn’t plural, but means something like “a big group of people” or so, so sort of plural. “Republic” has a similar meaning IMO. Of course it’s just my interpretation as I wanted some logic behind all those tricky rules about when to use articles.
So is the Fediverse though.
I think you can also think of it as “the Mississippi River”.
