Nadzorni inženjer mora provjeriti jamstvo za izvedene radove i skriveni nedostatak.

Nadzorni inženjer literally means supervising engineer or supervisory engineer.

• inženjer = engineer
• nadzorni = supervisory / supervising, from nadzor = supervision

Croatian often forms job titles this way: an adjective describes the role, and the noun names the profession. So instead of something like engineer of supervision, Croatian normally says nadzorni inženjer.

In construction and technical contexts, this usually refers to the engineer responsible for oversight or inspection.

Because Croatian uses morati + infinitive to mean must / has to.

So:

• mora = he/she/it must
• provjeriti = to check / to verify

Together, mora provjeriti = must check.

English uses must + base verb. Croatian uses morati + infinitive. There is no separate word like English to in this structure.

This is about aspect, which is very important in Croatian.

• provjeriti = perfective, meaning to check and complete the check
• provjeravati = imperfective, meaning to be checking, to check repeatedly, or to check in general

In mora provjeriti, the idea is that the engineer must perform a specific completed check. That is why the perfective infinitive provjeriti is natural here.

If you said mora provjeravati, it would suggest repeated or ongoing checking.

They are the direct objects of the verb provjeriti, so they are in the accusative case.

Here is the useful part:

• jamstvo is a neuter noun, and in singular its nominative and accusative forms are the same
• skriveni nedostatak is masculine inanimate, and in singular its nominative and accusative forms are also the same

So even though they are accusative objects, they look unchanged:

• jamstvo
• skriveni nedostatak

This is very common in Croatian.

Here za means for, and it takes the accusative.

So:

• za = for
• izvedene radove = completed / performed works

Both words agree in the accusative plural:

• radovi → radove
• izvedeni → izvedene

So jamstvo za izvedene radove means warranty/guarantee for the completed works.

In construction and legal/technical language, radovi usually means works, construction works, or work carried out, not works in the artistic sense.

• radovi = works / jobs / construction work
• izvedene = carried out / executed / completed

So izvedeni radovi are works that have been completed or carried out.

This is a very common technical phrase in Croatian.

Skriveni nedostatak is a standard legal and technical expression meaning hidden defect or latent defect.

• skriveni = hidden
• nedostatak = defect, flaw, deficiency

It refers to a defect that is not immediately visible or apparent at the time of inspection or handover.

Because it is such a fixed expression, learners often see it as a unit rather than just a random adjective + noun combination.

Yes, it could be plural if the meaning required it.

Here the singular can mean:

1. one specific hidden defect, or
2. the general legal concept of a hidden defect

In technical and legal Croatian, singular nouns are often used to name a category or issue in an abstract way.

If you meant several hidden defects, you would use the plural:

• skrivene nedostatke = hidden defects

Yes. In this sentence, i links two things that the engineer must check:

• jamstvo za izvedene radove
• skriveni nedostatak

So the structure is:

Nadzorni inženjer + mora provjeriti + [object 1] i [object 2]

A native speaker would normally understand this as two coordinated objects after the same verb.

If someone wanted to make it even clearer stylistically, they might rephrase it, but grammatically this structure is fine.

Because Croatian has no articles.

English distinguishes:

• a hidden defect
• the hidden defect

Croatian usually leaves that distinction to context. So skriveni nedostatak can mean:

• a hidden defect
• the hidden defect

depending on the situation.

The same is true for nadzorni inženjer and jamstvo.

Yes. Croatian word order is more flexible than English word order because case endings show grammatical roles.

The sentence as given is neutral and natural:

Nadzorni inženjer mora provjeriti jamstvo za izvedene radove i skriveni nedostatak.

But other orders are possible for emphasis, for example:

• Jamstvo za izvedene radove i skriveni nedostatak mora provjeriti nadzorni inženjer.

That version puts more focus on what must be checked.

So the original order is not the only possible one, but it is a normal default order.

They are very close in meaning, but jamstvo is often felt to be more standard or more formal, especially in legal or technical language.

• jamstvo = warranty, guarantee
• garancija = guarantee, also very common in everyday speech

In many contexts they overlap, but in official, contractual, or technical wording, jamstvo is often preferred.

Because the adjectives must agree with the nouns they describe.

• skriveni nedostatak

  • nedostatak is masculine singular
  • so the adjective is skriveni

• izvedene radove

  • radove is masculine plural accusative
  • so the adjective is izvedene

This is normal Croatian adjective agreement: adjectives change for gender, number, and case.

So the different endings are not random; they match the nouns they belong to.
