This is the 496th most frequent Serbian word.
сата
The Serbian word "сата" means "hours" in English.
Here, 'сата' is the plural form in genitive case of the word 'сат' (clock) because it follows a number (двa – 'two') that requires the genitive form.
Имам два сата на зиду.
I have two clocks on the wall.
In this context, 'сата' is in the genitive case, which is used here to express duration of time.
Чекао сам два сата на станици.
I waited for two hours at the station.
'Сата' is again in the genitive case, used alongside the number два (two), referring to the time duration.
