I wanted to say the the word afrikaner does not exist, but I looked it up and it seems that it does. But it actually only refers the white south-african people, that speak afrikaans (a part of the white south-africans speak english, so it does not refer to All white south-africans) Though I myself have only heard people from south africa being called Zuid-Afrikaan, whatever their background was. I dont think the term is really known here (anymore) unless you are studying linguistics or the local history.
And the word afrikaanse is just the female version of afrikaan. So a female from africa.
And people would only be mentioned by their country of origin if it was relevant for the story just like you have europeans and italians. Asians and japanese.
Debate chocks away!
And darn paraguay... I reallly should learn the capitals one of these days, I know about 75% of europe (linking them to the right country.. otherwise more like 90%) And a handfull of others outside of that. I dont think I get much further than about 50 capitals..
