Punomoćnik predočuje dokument.

Punomoćnik is nominative singular, because it is the subject of the sentence.

Dokument is accusative singular, because it is the direct object: it is the thing being presented.

So the structure is:

• punomoćnik = the person doing the action
• predočuje = the action
• dokument = the thing affected by the action

Because dokument is a masculine inanimate noun, and in Croatian the accusative singular of masculine inanimate nouns is usually the same as the nominative singular.

So:

• nominative: dokument
• accusative: dokument

That is completely normal.

Compare that with a masculine animate noun, where the accusative usually changes:

• nominative: punomoćnik
• accusative: punomoćnika

Predočuje is a 3rd person singular present-tense verb form.

It means:

• he presents
• she presents
• it presents
• depending on context, also is presenting

It matches the singular subject punomoćnik.

Croatian present tense often covers both English simple present and present continuous, so the sentence could correspond to either presents the document or is presenting the document, depending on context.

Croatian does not have articles.

So there is no separate word for:

• the
• a / an

That means Punomoćnik predočuje dokument could be understood as:

• The authorized representative presents the document
• An authorized representative presents a document

Context tells you which is meant.

Not exactly.

Punomoćnik is a person who is authorized to act on someone else’s behalf. Depending on context, it can mean:

• authorized representative
• proxy
• agent
• attorney-in-fact

In some situations it may be a lawyer, but the word itself does not automatically mean lawyer. A lawyer is more specifically odvjetnik.

So punomoćnik is about authority/representation, not necessarily about being a legal professional.

Yes. Croatian word order is more flexible than English word order.

The neutral order here is:

• Punomoćnik predočuje dokument.

But you could also say:

• Dokument predočuje punomoćnik.

That would sound more marked and would usually put more focus on dokument or create contrast.

Even when the order changes, case endings help show the grammatical roles. In this sentence, punomoćnik is clearly the subject.

Yes, in many contexts you could.

Croatian often allows the subject to be omitted if it is already clear from context. So:

• Predočuje dokument.

can mean:

• He/She is presenting the document

However, if you want to name the person explicitly, you keep punomoćnik.

So the full sentence is useful when you want to say who is doing the action.

It can be either.

Croatian present tense does not force the same distinction that English does. So the same Croatian form may correspond to:

• presents
• is presenting

The correct English translation depends on context.

If the sentence is describing a routine or general action, English often uses presents.

If it is describing what is happening right now, English often uses is presenting.

A rough English-friendly approximation is:

poo-no-MOCH-neek pre-DO-chu-ye DO-ku-ment

A few important sound notes:

• ć in punomoćnik is a softer sound than č
• č in predočuje is like ch in church
• j in Croatian sounds like English y
• u is pronounced like oo in food

So predočuje is roughly pre-DO-chu-ye.

This is a very common learner question.

In this sentence you see both:

• ć in punomoćnik
• č in predočuje

A useful approximation is:

• č = a harder ch sound, like in church
• ć = a softer sound, somewhat between English t
  • y and ch

English does not have a perfect match for ć, so learners usually need practice hearing and repeating it.

For beginners, the most important thing is to notice that Croatian treats č and ć as different letters and different sounds.

No. It is capitalized here only because it is the first word of the sentence.

If it appeared in the middle of a sentence, it would normally be written with a lowercase letter:

• Vidim da punomoćnik predočuje dokument.

So it is not a proper noun here.

This sentence is singular:

• punomoćnik = one authorized representative
• dokument = one document
• predočuje = singular verb form

A plural version would be:

• Punomoćnici predočuju dokumente.

That means Authorized representatives present documents or The authorized representatives are presenting documents.

So the changes are:

• punomoćnik → punomoćnici
• predočuje → predočuju
• dokument → dokumente
