All Nouns have gender, Masculine, Feminine, Nuetral and plural And depending on the nouns position in the sentence gives it a case: Nominative (Subject), Accusative (object being directly affected), Dative (indirectly affected), and Genetive (things being of or from something) I sugest looking at a website for better deffinitions if that is unclear. Now the case changes the der, die, or das like so.... Nom. der die das die Acc. den die das die Dat. dem der dem den Gen. des der des der
Best of luck to you.
Here, go to these two websites and your German will be as good as anyone in Germany (providing you like it)
Try them and please comment back if they don't work. :) :D
Please be careful when you use such a sentence. When you tell someone in a German speaking country "der XXX trinken" what 9 out of 10 people will comprehend is that this group of XXX or this X is an alcoholic. The sentence can only be used in a neutral meaning if you add what XXX are drinking ie. "Die Lehrer trinken Kaffee"
