Tražimo novčanu naknadu pod uvjetom da nema izvanredne okolnosti.

Here tražimo means we are seeking / requesting / claiming.

The verb tražiti can mean:

• to look for
• to seek
• to ask for / request
• to claim

In this sentence, because it is followed by novčanu naknadu (monetary compensation), the meaning is clearly we are claiming/requesting compensation, not physically looking for something.

Also, -mo shows 1st person plural, so tražimo = we seek / we request / we claim.

Because this is the direct object of tražimo, so it has to be in the accusative case.

Dictionary form:

• novčana naknada = monetary compensation
  
  • novčana = nominative singular feminine
  • naknada = nominative singular feminine

In the sentence, it changes to accusative singular feminine:

• novčanu naknadu

Both words change because the adjective must agree with the noun in:

• gender
• number
• case

So:

• novčana naknada → nominative
• novčanu naknadu → accusative

Because Croatian does not have articles like English.

So Croatian does not normally distinguish with separate words between:

• a compensation
• the compensation

The exact meaning is understood from context.

That means:

• novčanu naknadu can mean monetary compensation, a monetary compensation, or the monetary compensation, depending on the situation.

This is very normal in Croatian and one of the biggest differences from English.

Pod uvjetom da means on condition that or provided that.

It is a fairly formal expression, often used in:

• legal language
• official notices
• complaints
• contracts
• rules and conditions

So the sentence sounds more formal than if you used something like ako (if).

A rough structure is:

• pod uvjetom da + clause
• provided that + clause

Example:

• Doći ću pod uvjetom da imam vremena.
• I’ll come provided that I have time.

Because this expression uses the preposition pod, and here pod requires the instrumental case.

So:

• uvjet = nominative singular
• uvjetom = instrumental singular

That is why you get:

• pod uvjetom

Literally, this is something like under the condition, which helps explain why Croatian uses pod here.

So pod uvjetom da is a fixed phrase you should learn as a whole.

There are two separate things going on:

1. da introduces a subordinate clause
2. nema means there is not / there are not in this kind of sentence

So:

• pod uvjetom da nema... = provided that there is no...

About nema:

• It is the negative form of ima
• In existential meaning, ima / nema often work like English there is / there isn’t

For example:

• Ima problema. = There is a problem / There are problems.
• Nema problema. = There is no problem / There are no problems.

So da nema izvanredne okolnosti means something like:

• that there is no extraordinary circumstance

This is a very good question, because the form can be confusing.

After nema, Croatian normally uses the genitive.

The noun is:

• okolnost = circumstance

Its genitive singular is:

• okolnosti

So in this sentence, izvanredne okolnosti is best understood as:

• genitive singular
• of an extraordinary circumstance
• therefore: there is no extraordinary circumstance

That said, learners often notice that in many real-life legal or airline-passenger texts, Croatian more often uses the plural:

• nema izvanrednih okolnosti = there are no extraordinary circumstances

So:

• nema izvanredne okolnosti = singular, grammatical
• nema izvanrednih okolnosti = plural, also very common, and often more natural in formal contexts

Because the adjective has to match okolnosti in case, number, and gender.

The basic form is:

• izvanredna okolnost = an extraordinary circumstance

After nema, the noun goes into the genitive, so the adjective changes too:

• izvanredne okolnosti

Here that is:

• feminine
• singular
• genitive

If the phrase were plural genitive, it would be:

• izvanrednih okolnosti

So the adjective form tells you important grammatical information.

Yes, in many situations you could say:

• Tražimo novčanu naknadu ako nema izvanredne okolnosti.

But the tone changes.

Ako means if and is more neutral and everyday.

Pod uvjetom da means provided that / on condition that and sounds:

• more formal
• more legalistic
• more precise

So both can work, but pod uvjetom da is a better fit for formal or official language.

No, Croatian word order is more flexible than English, although some versions sound more natural than others.

Original:

• Tražimo novčanu naknadu pod uvjetom da nema izvanredne okolnosti.

You could also say:

• Pod uvjetom da nema izvanredne okolnosti, tražimo novčanu naknadu.

Both are understandable. The difference is mostly in emphasis:

• the original starts with the main action: we claim compensation
• the second starts with the condition: provided that...

Croatian often moves elements around for focus, emphasis, or style.

Yes, it is understandable and grammatically possible, but many native speakers would very likely use the plural in the last part, especially in formal/legal contexts:

• Tražimo novčanu naknadu pod uvjetom da nema izvanrednih okolnosti.

That version often sounds more idiomatic if the intended meaning is the general idea of extraordinary circumstances as a category.

So the given sentence is not impossible, but a learner should know that:

• izvanredne okolnosti here reads as singular genitive
• izvanrednih okolnosti is often the more expected formal phrasing if you mean extraordinary circumstances in general
