Produžiću ugovor sutra.

It is the future tense: specifically future I in Serbian.

The sentence means I will extend the contract tomorrow.

In this form:

• produžiću = I will extend
• ugovor = contract
• sutra = tomorrow

So the basic structure is:

• produžiću = future verb
• ugovor = object
• sutra = time expression

Because this is a very common Serbian way of forming the future.

The full future construction uses:

• the infinitive of the main verb
• plus a short form of hteti (ću, ćeš, će, ćemo, ćete, će)

With many verbs, when the short future auxiliary comes right after the infinitive, the final -i of the infinitive drops, and the auxiliary attaches to the verb:

• produžiti + ću → produžiću

So:

• produžiću = I will extend

This is standard and very common in everyday Serbian.

The dictionary form is produžiti.

That is the infinitive, meaning to extend / to prolong.

So the breakdown is:

• produžiti = to extend
• produžiću = I will extend

A learner should recognize that produžiću is not a different verb, just a future-tense form of produžiti.

That happens in the contracted future form.

Serbian often forms the future like this:

• infinitive minus final -i
• plus the clitic future auxiliary

So:

• produžiti → produžit-
• produžit + ću → produžiću

This is a normal spelling rule for this future pattern.

You will see the same thing in other verbs too:

• uraditi → uradiću = I will do
• videti → videću = I will see
• kupiti → kupiću = I will buy

Yes. That is also correct.

Serbian allows more than one way to build the future:

• Produžiću ugovor sutra.
• Ja ću produžiti ugovor sutra.

Both mean the same thing.

The difference is mostly in style, emphasis, and word order:

• produžiću is the contracted form
• ću produžiti is the separated form

Also, ja is usually omitted unless you want emphasis, because the verb form already shows the subject:

• produžiću already means I will extend

So ja is not necessary unless you want to stress I, as in I will do it.

It is in the accusative case, because it is the direct object of the verb produžiti.

The important thing is that for many masculine inanimate nouns, the accusative singular looks exactly the same as the nominative singular.

So:

• ugovor = nominative singular
• ugovor = accusative singular as well

That is why it appears unchanged.

Compare:

• Potpisujem ugovor. = I am signing the contract.
• Produžiću ugovor. = I will extend the contract.

In both sentences, ugovor is the object.

Sutra is not behaving like a regular noun here. It is functioning as an adverb of time, meaning tomorrow.

So you can think of it simply as a time word, not as something that needs case agreement in this sentence.

It tells you when the action will happen:

• Produžiću ugovor sutra. = I will extend the contract tomorrow.

No, Serbian word order is fairly flexible.

You can say:

• Produžiću ugovor sutra.
• Sutra ću produžiti ugovor.
• Ugovor ću produžiti sutra.

These all can work, but the emphasis changes slightly.

For example:

• Produžiću ugovor sutra. = neutral
• Sutra ću produžiti ugovor. = puts more focus on tomorrow
• Ugovor ću produžiti sutra. = can emphasize the contract

So the meaning stays basically the same, but the information focus shifts.

Because Serbian usually drops subject pronouns when they are not needed.

The ending in produžiću already tells you the subject is I.

So:

• Produžiću ugovor sutra. = perfectly natural
• Ja ću produžiti ugovor sutra. = also correct, but more explicit

You would usually add ja only for emphasis, contrast, or clarity.

For example:

• Ja ću produžiti ugovor, a on neće.
• I will extend the contract, but he won’t.

Yes, it matters.

Produžiti is a perfective verb. In this sentence, that makes sense because the speaker is talking about a completed future action: extending the contract as a single result.

Serbian often uses a perfective verb for future actions like this:

• Produžiću ugovor. = I will extend the contract.

The imperfective partner would be something like produžavati, which would suggest repeated, ongoing, or habitual action in the right context.

So here, produžiti is the natural choice because the action is seen as one completed event.

A rough pronunciation guide is:

• pro-doo-ZHEE-choo

A few key sounds:

• ž sounds like the s in measure
• ć is a soft sound, somewhat like a very soft ch, but more palatal
• ću sounds roughly like choo, though not exactly the English ch

So:

• produžiću ≈ pro-doo-ZHEE-choo

If you want to sound more natural, pay attention to the soft final part -ću.

The usual negative form would be:

• Neću produžiti ugovor sutra.
• I will not extend the contract tomorrow.

Notice that the negative future uses neću, written as one word.

So:

• ću = I will
• neću = I will not

You normally do not attach neću to the main verb the way ću can be attached.

A natural question would be:

• Hoćeš li produžiti ugovor sutra? = Will you extend the contract tomorrow?
• Hoće li produžiti ugovor sutra? = Will he/she extend the contract tomorrow?

If you want to ask about I, Serbian more often uses another wording such as:

• Da li ću produžiti ugovor sutra? = Will I extend the contract tomorrow?

So for yes/no questions, Serbian often uses:

• da li
• or hoćeš li / hoće li / ćemo li, depending on the subject

Usually, yes.

Produžiću ugovor sutra sounds more neutral and natural in many contexts.

Putting sutra at the end is very common when it simply adds time information after the main statement.

• Produžiću ugovor sutra. = neutral, everyday
• Produžiću sutra ugovor. = possible, but less neutral and more marked

So if you are unsure, Produžiću ugovor sutra is a very safe choice.
