It is possible on friday and saturday is this street empty?? Thanks

[kacenka9]

No, that would be a question. But we do accept "..... this street is empty.."

[cozarro]

Can i write here "...ulice pustá"?

[VladaFu]

Maybe, but I think it is closer to deserted.

Why does Saturday appear with declension and Friday does not?

[AgnusOinas]

They are both declined. You have probably noticed that some nouns (esp. masculine inanimate) look the same in the accusative as in the nominative. This is exactly what we see here - "pátek" in the accusative is also "pátek". Take a look at the declension table: https://en.wiktionary.org/wiki/p%C3%A1tek

aha! reading Patku in another exercise, I thought that was the accusative of Patek. Thank you
