Zamena stiže sutra.

Zamena is nominative singular.

In this sentence, it is the subject of the verb stiže, so nominative is the expected case. The basic dictionary form is zamena.

It is also a feminine noun, which you can often recognize from the ending -a.

Zamena is a noun meaning something like replacement, substitute, or stand-in, depending on context.

For example, it can refer to:

• a replacement person at work
• a substitute player in sports
• a replacement part or item

So in Serbian, just like in English, the exact nuance depends on the situation.

This is very common in Serbian.

Stiže is a present-tense form, but Serbian often uses the present tense to talk about a planned, expected, or scheduled future event, especially when there is a time word like sutra (tomorrow).

So:

• Zamena stiže sutra. literally looks like The replacement arrives tomorrow but in natural English it may be translated as The replacement is arriving tomorrow or The replacement arrives tomorrow.

This is similar to English sentences like:

• My train leaves tomorrow.
• She comes back next week.

Stiže is from the verb stizati, which means to be arriving / to arrive in an imperfective sense.

A learner may also notice the related verb stići, which is the perfective partner.

Very roughly:

• stizati = imperfective
• stići = perfective

In this sentence, stiže is the 3rd person singular present form of stizati.

Because the sentence is presenting the arrival as an expected event in a natural, everyday way.

If you used the perfective verb stići, the present form would be stigne, not stiže. Perfective present forms in Serbian often point more directly to a future completed event.

By contrast, stiže sutra is a very common, idiomatic way to say that something or someone is coming/arriving tomorrow.

So for a learner, the important thing is:

• stiže sutra sounds normal and natural
• it is one of those everyday present-for-future patterns

Sutra is an adverb, meaning tomorrow.

Because it is an adverb, it is not in a noun case here. It does not behave like a declined noun in this sentence. It simply tells you when the action happens.

So:

• zamena = subject
• stiže = verb
• sutra = time adverb

Yes. Serbian word order is fairly flexible.

The neutral order here is:

• Zamena stiže sutra.

But you could also hear:

• Sutra stiže zamena.
• Zamena sutra stiže.

These versions usually keep the same basic meaning, but the focus or emphasis changes.

For example:

• Sutra stiže zamena. puts more emphasis on tomorrow
• Zamena stiže sutra. is a straightforward neutral statement

No. Serbian does not have articles like a or the.

So zamena can mean:

• a replacement
• the replacement

Which one is meant depends on context.

That is completely normal in Serbian.

The two sounds English speakers often notice are:

• ž in stiže: like the sound in measure or vision
• ć in stiže: a soft Serbian ch-like sound, somewhat like t+y said together, but softer and more palatal than English ch

A rough pronunciation guide would be:

• zamena ≈ ZA-me-na
• stiže ≈ STEE-zhe
• sutra ≈ SOO-tra

These are only rough English approximations, but they help at first.

Yes, absolutely.

Because zamena can mean replacement, substitute, or stand-in, the best English translation depends on context.

For example:

• at work: The replacement is coming tomorrow
• in sports: The substitute is coming tomorrow
• for an object or part: The replacement arrives tomorrow

So the Serbian sentence itself is broad enough to cover several natural English choices.
