Veterinarski pregled počinje sutra.

Croatian does not have articles like the or a/an.

So:

• veterinarski pregled can mean the veterinary examination, a veterinary examination, or just veterinary examination
• the exact meaning depends on context

In this sentence, English usually needs the or a, but Croatian does not.

Literally, it means veterinary examination or veterinary check-up.

Breakdown:

• veterinarski = veterinary
• pregled = examination, inspection, check-up

So the phrase is a noun phrase meaning a/the veterinary exam/check-up.

Because veterinarski is an adjective, and it must agree with the noun it describes.

Here it describes pregled, which is:

• masculine
• singular
• nominative case

So the adjective also appears in the masculine singular nominative form:

• veterinarski pregled

If the noun changed, the adjective would change too.

It is in the nominative case.

Why?

Because it is the subject of the sentence — the thing that starts.

So:

• Veterinarski pregled = the subject
• počinje = starts/begins
• sutra = tomorrow

Yes. Pregled is a masculine noun.

That matters because adjectives must match the noun, which is why we get:

• veterinarski pregled

and not some other adjective ending.

This is very common in Croatian, just like in English.

Compare:

• English: The exam starts tomorrow.
• Croatian: Veterinarski pregled počinje sutra.

Even though the event is in the future, the present tense is often used for:

• scheduled events
• planned events
• things that are definitely going to happen

So počinje sutra is completely natural.

The infinitive is početi = to begin / to start.

Počinje means he/she/it starts or is starting, depending on context.

In this sentence, the subject is veterinarski pregled, which is grammatically third person singular, so:

• počinje = starts / begins

Because Croatian verbs do not always need a separate subject pronoun.

The subject is already stated:

• Veterinarski pregled = the veterinary examination

So počinje agrees with that noun and means:

• the veterinary examination starts

In other contexts, počinje could mean he starts, she starts, or it starts, but here the noun phrase makes it clear.

Yes. Croatian word order is more flexible than English word order.

This sentence could also be:

• Sutra počinje veterinarski pregled.
• Počinje sutra veterinarski pregled. (less neutral, more marked)

The most neutral version is:

• Veterinarski pregled počinje sutra.

Changing the order usually changes emphasis, not the basic meaning.

For example:

• Sutra počinje veterinarski pregled. puts more focus on tomorrow.

No. Sutra is used by itself.

• sutra = tomorrow

So you simply say:

• počinje sutra = starts tomorrow

No preposition is needed.

Yes, you could also use a future form, for example:

• Veterinarski pregled počet će sutra.

That also means The veterinary examination will start tomorrow.

But the present tense version:

• Veterinarski pregled počinje sutra

is very natural, especially for something scheduled or officially planned.

Roughly:

• počinje ≈ PO-chee-nye

A few useful sound notes:

• č sounds like ch in chocolate
• nj sounds like the ny in canyon
• Croatian spelling is quite regular, so words are usually pronounced close to how they are written

A rough English-friendly pronunciation is:

• veh-teh-ree-NAR-skee PREH-gled po-CHEE-nye SOO-tra

This is only approximate, but it helps with the main sounds.

A few notes:

• r is rolled or tapped
• j sounds like English y
• u is like oo in food

Not always. Pregled is a general word meaning:

• examination
• inspection
• review
• check-up

In this sentence, because of veterinarski, it most naturally means a veterinary examination/check-up.

So the adjective tells you what kind of examination it is.
