This is the 1551st most frequent Polish word.
demokracji
The Polish word "demokracji" means "democracy" in English.
The word "demokracji" is the possessive form (genitive case) of "demokracja" (democracy), used here to describe what the system is based on.
Demokracja jest podstawą naszego systemu politycznego.
Democracy is the foundation of our political system.
"Demokracji" is used here in the genitive case to specify the subject of discussion, which is "principles of democracy."
Uczniowie debatowali o zasadach demokracji.
The students debated the principles of democracy.
Again, "demokracji" in the genitive case illustrates the relationship, denoting 'values belonging to democracy' or 'associated with democracy'.
