Questions & Answers about Redovna služba je otvorena od ponedjeljka do petka.
How do the prepositions od and do affect the days of the week in this sentence?
Both od (from) and do (to/until) always require the Genitive case. This is the standard way to express temporal boundaries in Croatian. Because of this rule, the days of the week must change from their Nominative (dictionary) forms into their Genitive forms to show the start and end of the timeframe.
The dictionary words are ponedjeljak and petak. Where did the final a go in ponedjeljka and petka?
This is an example of the "fleeting a" (nepostojano a). Many masculine nouns ending in -ak drop that final a when a grammatical ending is added. So, ponedjeljak + -a (the Genitive ending) shrinks to ponedjeljka, and petak + -a shrinks to petka.
Why does the word otvorena end in -a here?
Otvorena (open) is acting as an adjective describing služba (service). Since služba is a feminine singular noun, the word describing it must also take the feminine singular ending -a.
Could I use the verb raditi (to work) instead of je otvorena?
Yes, absolutely! In Croatian, it is very common to say that a business or service "works" rather than "is open". Saying Redovna služba radi od ponedjeljka do petka sounds perfectly natural and means exactly the same thing.
