I would like to add "minister", as there are some fine distinctions on who is and who's not in a government. Still we call them all "ministers". Very confusing, and very obvious at the same time.

There are also the differences in organisation of American municipalities, oh what a glorious mess!

Then you have the differences between a state and its different main/bi-lands, not to say the not inhabited parts.

It is a lot that don't have an obvious description.

And btw, twin cities, I found a lot of errors and pretended I didn't see them. Don't tell anyone.

If this is the case, then maybe it
should just be kept as an intentionally broad property that captures what we
now find in the Wikipedias.

+1, the more broad the application of certain property is, the better.
We really don't need to be 100% specific with a property, if we can
exploit qualifiers.

I would not completely agree to this: otherwise we could just have a property "related to" and use qualifiers for the rest ;-) It's always about finding the right balance for each case. Many properties (probably most) have a predominant natural definition that is quite clear. Take "parent" as a simple example of a property that can have a very strict definition (biological parent) and still be practically useful and easy to understand. The trouble is often with properties that have a legal/political meaning since they are different in each legislation (which in itself changes over space and time). "Twin city" is such a case; "mayor" is another; also classes like "company" are like this. I think we do well to stick to the "folk terminology" in such cases, which lacks precision but caters to our users.

This can then be refined in the mid and long term (maybe using qualifiers, more properties, or new editing conventions). Each domain could have a dedicated Wikiproject to work this out (the Wikiproject Names is a great example of such an effort [1]).
