Concerning the citation and bibliography of my thesis, some issues I could solve myself, with others I got help. But here are two aspects, which I'd like to change, but I couldn't figure them out on my own:
-
I'd like the abbreviation to »et al.« for more than two authors in all in-text citations, beginning with the first mention. Currently on first mention it will look like »Author A / Author B / Author C 2000« and from second mention like »Author A et al. 2000«. Is there a modification available?
-
I'd like to add »S.« (german abbreviation for »Seite«, meaning »Page«) in all the citations of journals in the bibliography. It should look similar to book chapters. Is there a way to add that?
I'm using APA-Style with biber as backend for biblatex. All help is much appreciated.

Best Answer
Point 2 should be as easy as
Point 1 is more complicated. Given that you are already deviating far from APA style, it might be worth a try to just load the standard
authoryearstyle for citationsThe fact that you then still don't get "First Author et al." in your MWE is due to Set limit to one author when using "et al." in biblatex.
Note how I changed your
.bibentries. In particular the content of thelangidfield must be a language name known tobabel.
