Nice file bembe…a bit daunting but nice to have a free resource =D
I like the idea you presented from Luca…If you like it, write it down. Or, if you like it…use it in speaking or writing! What I usually think about is there are certain phrases we like to use in our native language. We could say certain things a half dozen or more ways, but we pick (usually) one and go with it most of the time. We don’t need to learn by heart, every single collocation such that we can USE it. We can pick one we like and go with it. i.e. there’s a few ways in German to say “it depends on, such and such”. Pick one and go with it. We’ll recognize the other ways these things can be said through our normal reading/listening/conversations, but we don’t have to memorize them all for active speech we use.
I’m oversimplifying things a bit as there are still so many of these things, even if we limit to ones we will use, but it seems like doing SRS with ALL the ways you can say a certain thing would be very self defeating and boring as heck. I think these will just be acquired through normal input.
Of course there are the other rules like you mention regarding dative/accusative etc. I guess I’m hoping all that comes naturally through input and if I get it wrong most natives might chuckle, but generally know what your are really trying to say.
