Ambulanta je blizu parka.

Not usually. In Serbian, ambulanta most often means a clinic, outpatient office, or medical practice, not the emergency vehicle.

So in this sentence, Ambulanta je blizu parka means that a medical facility is near the park.

If you mean the vehicle ambulance, Serbian often uses expressions like ambulantna kola, and for the emergency service people also commonly say hitna pomoć.

Je means is.

It is the 3rd person singular present-tense form of biti, which means to be.

So:

• ambulanta = clinic
• je = is
• blizu parka = near the park

Serbian usually does not need a subject pronoun here, so you do not say something like ona je unless you specifically want emphasis.

Because blizu requires the genitive case.

The basic dictionary form is:

• park = park

But after blizu you use the genitive:

• blizu parka = near the park

So the pattern is:

• blizu + genitive

More examples:

• blizu škole = near the school
• blizu kuće = near the house
• blizu grada = near the city

This is one of the most important grammar points in the sentence.

In this sentence, blizu functions like near.

You can think of it as a word that often behaves like a preposition when it is followed by a noun in the genitive case:

• blizu parka = near the park

It can also be used on its own more like an adverb:

• Bolnica je blizu. = The hospital is near / nearby.

So for a learner, the useful rule is:

• blizu + genitive noun
• or blizu by itself = nearby

Because Serbian does not have articles like a and the.

So ambulanta can mean:

• a clinic
• the clinic

And park can mean:

• a park
• the park

The exact meaning depends on context. In natural English, this sentence is often translated as The clinic is near the park, but Serbian itself does not mark that with articles.

No. Serbian word order is fairly flexible.

Ambulanta je blizu parka is the most neutral and straightforward order.

But you could also hear:

• Blizu parka je ambulanta.

This can sound a bit more like you are emphasizing the location near the park, or introducing the clinic from that location.

Because Serbian uses case endings, word order can change more freely than in English, though not every order sounds equally natural in every context.

A rough English-friendly pronunciation is:

ahm-boo-LAN-tah yeh BLEE-zoo PAR-kah

A few useful details:

• j in Serbian sounds like English y, so je sounds like ye
• z in blizu is a voiced z
• r in parka is a tapped or rolled Serbian r
• each written letter is pronounced quite consistently in Serbian

So the sentence is pronounced more or less exactly as it is spelled.

Sometimes yes, but they are not exactly the same.

• blizu parka = near the park
• pored parka = beside / next to the park
• kod parka = by the park / near the park

So:

• blizu is the general idea of near
• pored usually suggests being more directly beside something
• kod is common in everyday speech for location, but it can feel a bit less exact

If you just want the basic meaning near the park, blizu parka is an excellent choice.

Ambulanta is feminine.

You can tell because it ends in -a, which is a very common feminine ending in Serbian.

That matters when you add adjectives or pronouns. For example:

• Nova ambulanta je blizu parka. = The new clinic is near the park.

Here nova is the feminine form of new, matching ambulanta.

In your original sentence, you do not see much gender agreement yet, but it is still useful to know the noun is feminine.
