A question I’m hoping someone can help out with! In a sentence like this:
bei der Informierung unserer Kunden, Planung und Umsetzung von Aktivitäten, Entwicklung von Werbematerialien …
there is a whole list of nouns to which “bei der” refers. Ok, this sentence isn’t the best example as all the nouns are feminine anyway. But if there were several nouns of different genders, would “bei der” just have to agree with the first? I considered whether “bei den” could be used, as “bei” is really referring to several things, but I don’t think I’ve ever seen this. I’ve run into this problem quite often when writing out German exercises.
For example, if I wanted to write something like
Ich hatte genug von meinem Brüder, Schwester und Vetter
without repeating "mein" three times.
