Language /
I'm native Polish and I hate my own language. [106]
The last time anyone in the US used the word "preposition" in my presence was ... never
Then you lack any kind of meta-linguistic awareness (no wonder your Polish is all from google translate)
The same for plusquamperfectum
aka pluperfect or even more commonly past perfect.... impossible to speak English/American well without mastering it (and not a skill likely to be intuitively understood by an adult learner).
Now in Polish the past perfect is essentially moribund. I've heard it maybe....twice, once for sure by the editor of Kultura who had been living in France for decades (it's also important in French). I have the idea I may have heard it another time but I forget the specifics....
