Translation:He bought eggs and milk from a farmer.
Das heisst "bei einem Bauern". What the heck. We want to learn German Genitiv, correctly! :-( I post it here because there is no other option to report whats wrong, just ticking a bock, doesn't solve the problem.
Correction accepted, my bad, of course it is Dative. Not sure what made me state that it is Genitive. Well, in common speach you hear people dropping the 'n' which sounds bad to my ears. Anyway you wil get a lingot to setting this right. :-)
I noticed that when back to Germany recently, its a bit of a shame. Some of the spoken language sounds strange now to my ears. (have been to Berlin). Thats the obviously the evolution of the language, -not always a good thing.
