Potpisnik predočuje izvornik i punomoć.

Potpisnik means signer or signatory.

Grammatically, it is a masculine singular noun. In legal and administrative Croatian, the masculine form is often used as a general label for a person in that role, not necessarily only for a male person.

If you specifically wanted the feminine form, it would be potpisnica.

Here, predočuje means something like presents, shows, or submits for inspection.

It is a fairly formal word, especially common in legal, administrative, and official contexts. In everyday speech, Croatian speakers might more often use a verb like pokazuje depending on the situation, but predočuje is very natural in formal documents.

The dictionary form is predočiti.

Predočuje is the 3rd person singular present form, used because the subject potpisnik is he/she/the signatory, singular.

So the structure is:

potpisnik = the subject
predočuje = presents/shows
izvornik i punomoć = the things being presented

Potpisnik is in the nominative singular because it is the subject of the sentence.

Izvornik and punomoć are in the accusative singular because they are the direct objects of the verb predočuje.

So, grammatically:

• potpisnik = nominative
• izvornik = accusative
• punomoć = accusative

Because in this sentence, their accusative singular happens to be identical to their nominative singular.

That is normal here:

• izvornik is a masculine inanimate noun, and masculine inanimate nouns usually have the same form in nominative and accusative singular.
• punomoć is a feminine noun of a type whose accusative singular is also the same as the nominative singular.

So even though they are objects, their forms do not visibly change here.

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

Whether the meaning is the original and the power of attorney or an original and a power of attorney depends on context.

In a legal or official sentence like this, the meaning is usually understood as referring to the required specific documents.

Izvornik means the original document, not a copy.

Punomoć means power of attorney or authorization, especially a document giving someone legal authority to act on another person’s behalf.

So this sentence is talking about presenting two things:

• the original document
• the power of attorney

Croatian often leaves this unstated when the context makes it obvious.

In a legal or administrative setting, the recipient might be a notary, official, clerk, or another authorized person. The sentence focuses on what the signatory must present, not necessarily to whom.

If needed, Croatian could state the recipient explicitly, for example with a dative phrase such as javnom bilježniku.

The order Potpisnik predočuje izvornik i punomoć is the most neutral and standard order:

subject + verb + object

Croatian word order is more flexible than English, so other orders are possible, but they would usually sound more marked, more literary, or more context-dependent.

In official language, the neutral order is preferred because it is clear and straightforward.
