This is the 1045th most frequent Polish word.
banków
"Banków" means "banks" (plural, genitive case) in English.
The word 'banków' is used here in the genitive plural form of 'bank,' referring to multiple financial institutions.
Mam wiele banków w moim mieście.
I have many banks in my city.
Again, 'banków' is in the genitive plural, used to indicate non-specific reference to more than one bank as an object of the discussion.
Pomysł otwierania nowych banków jest dyskutowany.
The idea of opening new banks is being discussed.
Here, 'banków' serves as the object of the preposition 'dotyczących,' which requires genitive case; thus, it represents multiple banks in a general context.
