Questions & Answers about Potvrdu o prijavi čuvajte dok traje privremeni odlazak.

Why is potvrdu in the form potvrdu and not potvrda?

Because it is the direct object of the imperative verb čuvajte (keep).

• potvrda = nominative singular (a certificate / confirmation)
• potvrdu = accusative singular

In Croatian, a direct object often goes into the accusative case, so:

• Čuvajte potvrdu = Keep the certificate

That is why you see potvrdu here.

Why is it o prijavi and not prijavu?

Because the preposition o normally takes the locative case when it means about / concerning.

So:

• prijava = nominative
• prijavi = locative singular

In this phrase, potvrda o prijavi means something like confirmation/certificate of registration or confirmation regarding the registration.

This is a very common administrative pattern in Croatian:

• odluka o nečemu = decision about something
• obavijest o nečemu = notice about something
• potvrda o nečemu = confirmation/certificate of something

So o prijavi is there because of the noun phrase, not because of the verb čuvajte.
