The truth is that different persons need different teaching methods.
Of course the teacher should take under consideration learners aprroach but we cannot change the specificity of the Polish language. I belive everybody in an individual, but mechanism is general. Especially at the begining of the learning process teaching methods
should be very similar for everybody. Of course it they work (-:
Not genders, cases. There are seven cases (the ones listed by SzwedwPolsce) and three genders (masculine, feminine, neutrum)
Male, Female, Neutrum
but also in Plural
Male people/personal gender and Not male people/personal gender
That is why you say:
" but "koty były
" however "profesor" is male and "kot" is male in singular
male animated versus male inanimate
this is important in Acc. and Gen. plural
In plural we make also a difference between
male personal and male animated
So it looks like seven I am afraid (-:
But the point is not how many cases we have.
Polish is like a machin which has logic inside
If you understand how it works and you get efficient
exercises to practise it you can learn it very fast.
But to do it you need a succesful method which depends more on
Polish language requirement then on individual expectations of learners.
Polish has an objective structure. If you want to speak Polish you have to get
inside it. Nevermind if you like it or not (-:
