Najprije odjavite boravište, a onda prijavite prebivalište i adresu stanovanja.

Najprije means first or first of all.

In this sentence, najprije and prvo would be very close in meaning. Both can introduce the first step in a sequence.

• najprije = first, at first, first of all
• prvo = first

Najprije can sound a little more like to begin with / as the first step, while prvo is often the most everyday option. In official instructions like this, najprije sounds perfectly natural.

The ending -te marks the imperative for:

• you plural
• or formal you singular

So odjavite means deregister! and prijavite means register!, addressed either to:

• one person formally, or
• more than one person

This is very common in instructions, notices, and official language.

Examples:

• Pričekajte. = Wait.
• Ispunite obrazac. = Fill in the form.

Grammatically, it can be either:

• one person, formally
• several people

Croatian uses the same imperative form in -te for both.

In this kind of administrative instruction, it is usually best understood as a formal instruction to the reader.

These are important legal/administrative terms in Croatian.

• boravište = temporary residence
• prebivalište = permanent residence

So the sentence is talking about two different kinds of official address status.

Very roughly:

• boravište = where you are currently staying temporarily
• prebivalište = your main, official place of residence

This distinction is especially important in Croatian bureaucracy and legal documents.

Yes. They are closely related.

• prijaviti = to register, report, declare
• odjaviti = to deregister, unregister, sign off

The prefixes change the meaning:

• pri- often gives the sense of adding, submitting, registering
• od- often gives the sense of removing, away from, deregistering

So here the logic is:

1. odjavite boravište = deregister your temporary residence
2. prijavite prebivalište i adresu stanovanja = register your permanent residence and address

Because adresu is the direct object of prijavite, so it must be in the accusative case.

The base form is:

• adresa = address

But after prijaviti in this sentence, it becomes:

• adresu = address, in the accusative singular

So:

• prijavite adresu = register the address

They are direct objects, so they are in the accusative case.

• boravište → accusative singular
• prebivalište → accusative singular
• adresu → accusative singular
• stanovanja stays in the genitive

A useful detail:
For many neuter nouns like boravište and prebivalište, the nominative and accusative forms look the same. So even though they are accusative here, they look unchanged.

Because stanovanja is in the genitive case, used after adresa.

The phrase adresa stanovanja means something like:

• address of residence
• residential address

This is a common noun + genitive pattern in Croatian.

So:

• adresa = address
• stanovanje = residence / living
• adresa stanovanja = address of residence

In the sentence, because adresa becomes adresu, the second noun still stays genitive:

• adresu stanovanja

Yes.

It comes from the same word family:

• stanovati = to live, to reside
• stanovanje = living, residence, housing
• stanovanja = genitive form of stanovanje

So adresa stanovanja is built from the noun stanovanje, not directly from the verb, but they are definitely related.

Here a onda means and then or then.

• onda = then
• a here links the two actions and marks the next step in the sequence

In Croatian, a often connects clauses with a slight sense of contrast or transition, but it can also simply move the listener from one step to the next.

So the structure is:

• Najprije... = First...
• a onda... = and then...

This sounds natural in instructions.

Because it is understood from the context.

In instructions, Croatian often leaves out possessives when the meaning is obvious. If a form or notice tells you to register or deregister something, it is naturally understood to mean your own residence/address.

So:

• odjavite boravište naturally means deregister your temporary residence
• prijavite prebivalište naturally means register your permanent residence

Adding svoje is possible in some contexts, but it is not necessary here.

Yes, in this sentence they are perfective imperatives.

• odjaviti = to deregister completely
• prijaviti = to register completely

Perfective verbs are very common in instructions when the speaker is telling someone to perform a complete action.

That fits this context well, because these are one-time administrative actions with a clear result.

A rough contrast would be:

• prijavljivati = to be registering / to register repeatedly or habitually
• prijaviti = to register once, successfully, as a completed act

Yes, Croatian word order is fairly flexible, but the original order is natural and clear.

Original:

• Najprije odjavite boravište, a onda prijavite prebivalište i adresu stanovanja.

Possible variation:

• Boravište najprije odjavite, a onda prijavite prebivalište i adresu stanovanja.

But the original sounds better for neutral official instructions because it presents the steps in a straightforward way:

1. najprije = first
2. odjavite boravište
3. a onda = and then
4. prijavite prebivalište i adresu stanovanja

It sounds official / administrative / bureaucratic.

Clues include:

• the legal terms boravište and prebivalište
• the formal imperative odjavite / prijavite
• the phrase adresa stanovanja

A Croatian speaker would strongly associate this with government offices, forms, instructions, or legal procedures rather than casual conversation.

In everyday speech, people might explain the same idea in a less formal way, but this sentence is exactly the kind of wording you would expect in official guidance.
