Da li je ova prodavnica otvorena sada, ili je zatvorena?

Da li is a very common way to turn a statement into a yes/no question in Serbian.

So:

• Ova prodavnica je otvorena. = This store is open.
• Da li je ova prodavnica otvorena? = Is this store open?

It does not translate word-for-word very neatly into English. You can think of it as a question marker, similar in function to putting is/are/do/does at the beginning of an English question.

Because in this kind of Serbian question, the usual pattern is:

Da li + verb + rest of the sentence

So:

• Da li je ova prodavnica otvorena?

The verb je means is.
This is the normal and natural order for this structure.

Because the sentence has two parts joined by ili = or:

• Da li je ova prodavnica otvorena sada
• ili je zatvorena

In English, we also repeat the verb:

• Is this store open now, or is it closed?

So Serbian repeats je for the second clause just like English repeats is.

Ova means this.

It changes form to match the gender of the noun:

• ovaj = this, for masculine nouns
• ova = this, for feminine nouns
• ovo = this, for neuter nouns

Prodavnica is a feminine noun, so the correct form is ova prodavnica.

Because they are adjectives, and they must agree with prodavnica, which is feminine singular.

So:

• otvoren = open
• zatvoren = closed

But with a feminine singular noun, they become:

• otvorena
• zatvorena

This is grammatical agreement, and it is very important in Serbian.

In this sentence, it works as a predicate adjective with je:

• je otvorena = is open
• je zatvorena = is closed

So literally, the structure is similar to:

• The store is open
• The store is closed

It is not a separate full verb like opens or closes. It is the verb to be plus an adjective.

Sada means now.

In this sentence:

• Da li je ova prodavnica otvorena sada...?

that is perfectly understandable and natural.

You may also hear sad, which is a very common shorter form in everyday speech:

• Da li je ova prodavnica otvorena sad?

In many situations, sad sounds a bit more conversational, while sada can sound slightly more neutral or careful.

Yes. If the context already makes it clear that you mean now, you can say:

• Da li je ova prodavnica otvorena, ili je zatvorena?

But adding sada makes the time reference explicit, which is often useful.

No. Prodavnica is a very common general word for store/shop.

Another common word is radnja, which can also mean shop/store, depending on context.

In many everyday situations, prodavnica is a safe and natural choice, especially for a general store or shop.

No. It is one very common and standard way, but not the only one.

You may also hear:

• Je li ova prodavnica otvorena sada, ili je zatvorena?
• Ova prodavnica je otvorena sada, ili je zatvorena? with question intonation

However, da li je... is very useful for learners because it is clear, standard, and easy to build correctly.

Ili means or.

In this sentence it connects two alternatives:

• open now
• closed

So:

• ...otvorena sada, ili je zatvorena?
• ...open now, or is it closed?

It is a very common conjunction in Serbian.

In prodavnica, the letter c is pronounced like ts in cats.

So prodavnica is approximately:

• pro-da-vni-tsa

A rough English-friendly pronunciation guide for the whole sentence is:

• Da li je ova prodavnica otvorena sada, ili je zatvorena?
• DA lee yeh OH-va pro-da-VNI-tsa ot-VO-re-na SA-da, EE-lee yeh za-TVO-re-na?

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

Yes, that is grammatically correct.

It would mean roughly the same thing, using radnja instead of prodavnica. Just remember that radnja is also feminine, so the rest still agrees the same way:

• ova radnja
• otvorena
• zatvorena

So the grammar stays parallel.
