Picture with a slightly run-down looking church's front door on the right side of the picture, and on the left a section of the church's wall and a graffiti-covered dumpster in front of it.
On the wall is graffitied a 4x4 table with the columns labeled from left to right "M", "F", "N" and "PL" – for the masculine, feminine, neuter and plural forms. The rows are labeled from top to bottom "nom", "akk", "dat", "gen" for the nominative, accusative, dative and genetive cases. The corresponding definite articles are written out in the table each in its own spot (I hope screen readers don't barf with tables):
Argh, I was squinting at the text and just went "… I think it was dem? I'm pretty sure it's dem" As I said in another comment, grammar has never been my strong suit (in any language)
To be honest, I have no idea how anyone can memorise that. As a native speaker you hardly ever really think about it, you just know. But looking at the table it just seems like complete chaos, even to me.
Es gibt wohl einige Länder, die den Akkusativ zumindest in der Lateindidaktik nach den Nominativ setzen. Frag mich nicht, welche bahnbrechenden pädagogischen Erkenntnisse dazu geführt haben – macht in internationalen Lateinforen immer mal wieder etwas Konfusion, welches nun genau der "zweite Fall" ist...
