Moramo razjasniti nesporazum.

• Moramo = we must / we have to
• razjasniti = to clarify / to clear up
• nesporazum = misunderstanding

So the sentence literally means something like We must clarify a misunderstanding or We need to clear up the misunderstanding.

Croatian often leaves out subject pronouns when they are already clear from the verb ending.

• moram = I must
• moraš = you must
• mora = he/she/it must
• moramo = we must

Because -mo already shows we, adding mi is usually unnecessary.

You can say Mi moramo razjasniti nesporazum, but that adds emphasis, as if you mean we (not someone else) have to do it.

After modal verbs like morati (must / have to), Croatian normally uses the infinitive.

So:

• moramo razjasniti = we must clarify

This is the standard Croatian structure:

• moram raditi = I have to work
• moramo razgovarati = we have to talk
• moraju doći = they must come

This is a question of aspect, which is very important in Croatian verbs.

• razjasniti = perfective → to clarify completely, to clear up
• razjašnjavati = imperfective → to be clarifying, to clarify repeatedly or over time

In Moramo razjasniti nesporazum, the speaker is focusing on the result: the misunderstanding needs to be cleared up.

So this sounds natural when you mean:

• we need to resolve it
• we need to get it settled

If you used razjašnjavati, it would sound more like an ongoing process rather than a completed outcome.

Nesporazum is the direct object of razjasniti, so it is in the accusative case.

However, nesporazum is a masculine inanimate noun, and for many masculine inanimate nouns, the accusative singular looks exactly the same as the nominative singular.

So:

• nominative: nesporazum
• accusative: nesporazum

That is why the form does not change here.

Croatian does not have articles like English a / an / the.

So nesporazum can mean:

• a misunderstanding
• the misunderstanding

The exact meaning depends on context.

In this sentence, English could translate it either way:

• We need to clear up a misunderstanding
• We need to clear up the misunderstanding

Both are possible depending on the situation.

Yes. This is a very natural, neutral word order in Croatian.

• Moramo = the verb expressing obligation
• razjasniti = the infinitive
• nesporazum = the object

Croatian word order is fairly flexible, though, so you could also hear:

• Nesporazum moramo razjasniti.

That version gives extra emphasis to nesporazum.

But the original sentence is the most neutral and straightforward version.

They are related, but not the same.

• razjasniti = to clarify / clear up
• objasniti = to explain

So:

• razjasniti nesporazum = clear up a misunderstanding
• objasniti nesporazum would sound more like explain what the misunderstanding is

In this sentence, razjasniti is the better choice because the idea is not just giving an explanation, but resolving confusion.

Yes, absolutely. That is also natural.

The difference is roughly:

• moramo = we must / we have to → stronger obligation
• trebamo = we need to / we should → often a bit softer

So:

• Moramo razjasniti nesporazum = stronger, more urgent
• Trebamo razjasniti nesporazum = slightly softer

In real conversation, both can work, depending on tone.

A rough pronunciation guide is:

mo-RA-mo raz-YA-sni-ti ne-spo-RA-zum

A few helpful notes:

• j is pronounced like English y
• r is rolled or tapped
• Croatian vowels are usually clear and consistent:
  • a as in father
  • i as in machine
  • u as in rule

So razjasniti has a y sound in the middle: raz-yas-ni-ti.

In standard Croatian, after morati, the normal and preferred pattern is:

• moramo razjasniti

Using da + present tense here is generally not standard Croatian style:

• moramo da razjasnimo

That kind of structure is much more associated with Serbian and some regional speech.

So if you are learning standard Croatian, use the infinitive:

• Moramo razjasniti nesporazum.
