Basically how reddit would call any given reddit sub-community “sub reddit” or just “sub” for short. I know internally lemmy just calls them ‘community’ but in a regular conversation ‘community’ might be interpreted as more broad or too general.
Thinking about it my mind would pretty much automatically go to ‘sub lemmy’, but then I felt like just shortening it to ‘blemmy’ has a great ring to it, while still being distinct. So if there isn’t already an established name, I’ll go ahead and propose ‘blemmy’.
Thing is, with the naming of the communities there are plenty of cases where saying something like “the [name] community” could easily be misinterpreted. “the linux community”, “the android community”, “the league of legends community”, and so on could either specifically mean the community on lemmy.worlds, or just the general community/fan base of something. In a case where something is only meant to specifically refer to the community on lemmy.worlds, a distinct word would be pretty helpful to make that clear and leave no room for misinterpretation.
