While trying to finally nail the adjective endings I stumbled upon this article suggesting a simplified way of learning it:
https://www.learn-german-smarter.com/learn-german-adjective-endings/
But either I do not understand their 2nd principle or the entire idea falls apart while dealing with an example like this:
Ich bin im rheinhessischen Dorf Wiesoppenheim aufgewachsen.
Okay, that's a dual preposition and dative. If I understand the article correctly dative results in an im (in dem)
but then where does the en
ending in rheinhessischen
come from?
Can someone please clarify?
Edit: Also I don't see how this unified table in the article will work with plurals. For instance for this example (plural and nominative):
Die anderen Kinder sind bösartig.
It would suggest e
ending while the correct one is en
. Does it also fall back to the 2nd principle where Die
takes a case ending e
? Where does the en
came from again?
