In my book, there is a differentiation of two types of personenbezeichnung made, it is categorized as primär and sekundär, however this is never explained further.
It's about semantics.
Primär: Mensch, Gast, Laie, Passagier, Insasse, Star, Flüchtling, Abkömmling, ...-ling
Sekundär: Vormund, Figur, Person, Putzkraft, ...-kraft, ...-hilfe, Wesen, Mitglied, Opfer, Individuum, Geschöpf.
I do not understand the difference between them. I have looked up "primär" and "sekundär" in this context but I can't find more about it. Note: It is in a professional publication by an educated author, so there is reason to understand this distinction.
