Izvoli, sjedni i ispuni obrazac prijave.

Izvoli is a very common Croatian word used when offering, inviting, or politely prompting someone to do something.

In this sentence, it means something like:

• go ahead
• please
• here you are
• feel free

So Izvoli, sjedni i ispuni obrazac prijave has the tone of politely welcoming someone and telling them what to do next.

A few important points:

• izvoli is singular informal — used when speaking to one person with ti
• the formal/plural version is izvolite
• by itself, izvoli can also mean here you are when handing something to someone

So here it is not a literal verb like English take or want, but a polite conversational cue.

Both forms exist, but they do not mean exactly the same thing.

• sjedni = sit down / take a seat
• sjedi = be sitting or, in some contexts, a less natural imperative for learners to use

In everyday Croatian, when you tell someone to move into the sitting position, sjedni is the normal choice.

This is because Croatian often uses different verb forms depending on whether the action is seen as:

• completed / single action → sjesti → imperative sjedni
• ongoing / repeated state → sjediti → imperative sjedi

Here the speaker wants the person to perform the action of sitting down, so sjedni is correct.

Because the speaker wants the person to complete one whole action: fill out the form.

Croatian verbs often come in aspect pairs:

• ispuniti = to fill out completely (perfective)
• ispunjavati = to be filling out / to fill out repeatedly (imperfective)

The imperative ispuni comes from the perfective verb ispuniti, and it means:

• fill it out
• complete the form

If you said ispunjavaj, it would sound more like:

• keep filling it out
• fill it out repeatedly
• or an ongoing process, which is not the normal meaning here

For instructions involving one finished task, Croatian commonly uses the perfective imperative.

They are both imperative forms, used for commands, requests, and instructions.

In this sentence:

• izvoli = imperative
• sjedni = imperative
• ispuni = imperative

All three are directed at one person informally.

The basic verb forms are:

• izvoljeti / izvoli in polite expression usage
• sjesti → sjedni
• ispuniti → ispuni

So the whole sentence is a sequence of polite instructions: Go ahead, sit down and fill out the application form.

It is informal singular.

You can tell because the imperatives are:

• izvoli
• sjedni
• ispuni

These are used when addressing one person with ti.

If you wanted to say the same thing formally, or to more than one person, you would usually say:

• Izvolite, sjednite i ispunite obrazac prijave.

So:

• izvoli / sjedni / ispuni = informal singular
• izvolite / sjednite / ispunite = formal singular or plural

Obrazac prijave means application form.

It is made of:

• obrazac = form
• prijave = of application / application

This is a very common Croatian structure: one noun is followed by another noun in the genitive case to show a relationship similar to English noun + noun combinations.

English often says:

• application form
• registration form
• passport form

Croatian more often expresses this as:

• obrazac prijave = form of application
• literally closer to the form of the application

So yes, the second noun is there because Croatian often uses genitive where English uses a noun as an adjective.

Because after obrazac, the noun prijava goes into the genitive singular.

The noun is:

• nominative: prijava = application
• genitive: prijave = of the application

So:

• obrazac = form
• obrazac prijave = application form

This is a regular case pattern. Croatian uses case endings to show relationships between words, and here the relationship is roughly form of application.

Not very naturally.

A very literal breakdown would be:

• Izvoli = go ahead / please
• sjedni = sit down
• i = and
• ispuni = fill out / complete
• obrazac prijave = application form

But a natural English translation would usually be something like:

• Please, have a seat and fill out the application form.
• Go ahead, sit down and fill out the application form.

The main reason a word-for-word translation sounds odd is izvoli, because English does not have one exact everyday equivalent for it.

Because Croatian has no articles like English a and the.

So obrazac prijave can mean:

• an application form
• the application form

Which one is meant depends on the context.

In a situation like a receptionist speaking to a visitor, it will often be understood as the application form or simply the form you need to fill out.

Croatian relies on context much more than English for this.

The comma after izvoli separates it from the rest of the instruction.

Here izvoli works a bit like a discourse marker or polite introductory prompt, so the comma is natural:

• Izvoli, sjedni...

The second part, sjedni i ispuni, does not need a comma because the two imperatives are simply joined by i = and.

So the punctuation reflects the structure:

• Izvoli, = polite lead-in
• sjedni i ispuni obrazac prijave = the actual actions

Usually no — in this kind of context, it sounds polite, not rude.

Even though it is grammatically an imperative, in real usage izvoli often softens the instruction. It can make the sentence sound more welcoming, like:

• Please
• Go ahead
• Feel free

Without izvoli, the sentence would still be correct:

• Sjedni i ispuni obrazac prijave.

But that sounds more direct. Adding izvoli makes it friendlier.

As always, tone and situation matter. Said warmly, it is polite and normal.

The given word order is the most natural one for this situation.

• Izvoli, sjedni i ispuni obrazac prijave.

Some variation is possible in Croatian, but not all versions sound equally natural.

For example, putting obrazac prijave earlier would be unusual unless you were emphasizing it.

Croatian word order is fairly flexible, but it still follows information structure and natural rhythm. In everyday instructions, speakers usually prefer the straightforward order:

1. polite cue
2. first action
3. second action
4. object

So this sentence is a good model to learn as it stands.

Yes, depending on context.

Possible related expressions include:

• prijavni obrazac = application form
• obrazac za prijavu = form for application / application form

These are all understandable, but they are not always identical in style.

Compared with them:

• obrazac prijave sounds normal and standard
• prijavni obrazac uses an adjective-like form
• obrazac za prijavu is a more explicit for + noun structure

All three can appear in real Croatian, but the sentence you were given is perfectly natural.
