Oglas za radno mesto ima rok.

A natural word-by-word breakdown is:

• oglas = advertisement, notice, posting, ad
• za = for
• radno mesto = job position, post, work position
• ima = has
• rok = deadline, time limit

So the sentence means something like The job ad has a deadline or The job posting has a closing date.

Because za here means for, so oglas za radno mesto means an ad for a job position.

This is a very common Serbian pattern:

• oglas za stan = an ad for an apartment
• oglas za posao = a job ad
• konkurs za posao = a job opening / competition for a job

Here, radno mesto is the thing the ad is for.

After za in this meaning, Serbian uses the accusative case.

So radno mesto is in the accusative singular. The reason it looks unchanged is that for many neuter singular nouns, the nominative and accusative forms are identical.

For example:

• nominative: radno mesto
• accusative: radno mesto

The adjective also matches:

• radno = neuter singular nominative/accusative
• mesto = neuter singular nominative/accusative

So even though the case has changed, the form stays the same.

Not exactly.

• radno mesto = a job position, post, work position
• posao = job, work

In many contexts, English would just say job, but Serbian can be a bit more specific.

So:

• oglas za posao = job ad
• oglas za radno mesto = ad for a specific position/post

Both are possible, but oglas za posao is often more everyday and idiomatic.

Rok is a flexible word that often means:

• deadline
• time limit
• due date
• term

In this sentence, the most natural interpretation is deadline or closing date.

For a job ad, that usually means something like:

• the deadline to apply
• the date until which the ad is valid

If you want to be more specific, Serbian often says:

• rok za prijavu = application deadline
• rok trajanja oglasa = validity period / expiration period of the ad

So ima rok is understandable, but context tells you what kind of deadline is meant.

Ima is the 3rd person singular of imati = to have.

The subject is oglas, which is singular, so the verb is singular too:

• oglas ima = the ad has

This is completely normal Serbian. Just like in English, Serbian often expresses this idea with have:

• Sastanak ima datum. = The meeting has a date.
• Ugovor ima rok. = The contract has a deadline/term.

Because Serbian has no articles.

So oglas can mean:

• an ad
• the ad

The exact meaning depends on context.

That means Oglas za radno mesto ima rok could be understood as:

• The job ad has a deadline
• A job ad has a deadline

In real use, the surrounding conversation tells you which one is intended.

Not completely, but Oglas za radno mesto ima rok is the most neutral and natural order.

Serbian word order is more flexible than English because case endings help show grammatical roles. Still, not every possible order sounds equally natural.

This version is the straightforward subject + verb + object pattern:

• Oglas za radno mesto = subject
• ima = verb
• rok = object

If you change the order, you usually create emphasis or a less neutral tone. For a learner, this sentence is a very good default model.

A native speaker can say ima rok, and it is understandable. But in many real-life situations, something more specific is more natural, such as:

• Oglas za radno mesto ima rok za prijavu. = The job ad has an application deadline.
• Oglas za radno mesto važi do petka. = The job ad is valid until Friday.
• Rok za prijavu je do 15. maja. = The application deadline is until May 15.

So your sentence is fine, but it is somewhat short and context-dependent.

Yes, absolutely.

That version is often more natural in everyday speech:

• oglas za posao = job ad
• oglas za radno mesto = ad for a job position

The difference is mostly nuance:

• posao is broader and more common in casual language
• radno mesto sounds a bit more formal or specific

So both are correct, and which one you choose depends on style and context.
