er hat einer anderen Blockflöten-Unterricht gegeben From a friends episode... the Friends are watching a daytime drama (soap opera) on TV together ....A lady in the show on TV speaks to another lady in the show, then Monica makes a comment to her friends about the events in the show. This is from S01E01, at 5:02 into the episode. 5:02 Soap Opera Lady: Es reicht! So kann es mit uns beiden wirklich nicht mehr weitergehen. Wie konntest du mich so derartig belügen? That‘s enough! We both really can‘t go on like this. How could you lie to me like that? Monica: ich nehme an, er hat mal wieder einer anderen blockflöten-unterricht gegeben. I guess he has once again given another flute lesson. The grammar is odd to me. 1) Unterricht is Masculine (a DER word), but she clearly says either "eine" or "einer" - I'm not sure which, but I know it is not "ein / einen / einem". 2) Is it correct to write "Blockflöten-Unterricht" as a compound word, with a dash (minus zwischen den Wörter)? Which word, in this type of case, determines the gender of "ein / eine"? (ein Unterricht / eine Blockflöte) 3) is it "eineR andereN"? If so, then why is it dative?
