Nie tylko przynoszę oryginał, ale też proszę o potwierdzenie z urzędu.

This is the standard Polish way to say not only ... but also ...

• nie tylko = not only
• ale też = but also

So the structure links two parallel ideas:

• Nie tylko przynoszę oryginał = I’m not only bringing the original
• ale też proszę o potwierdzenie z urzędu = but I’m also asking for confirmation from the office

You may also see:

• nie tylko ... ale także ...
• nie tylko ... lecz także ...

These are very similar, with ale też sounding natural and common in everyday speech.

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

Here:

• przynoszę = I bring / I am bringing
• proszę = I ask / I am asking

The ending -ę shows first person singular, so ja is not necessary.

You could say:

• Ja nie tylko przynoszę oryginał, ale też proszę o potwierdzenie z urzędu.

But adding ja usually gives extra emphasis, something like:

• I’m the one who is not only bringing the original...

Without ja, the sentence is more neutral and natural.

In Polish, the present tense often covers both:

• I bring
• I am bringing

and

• I ask
• I am asking

So:

• przynoszę can mean I bring or I’m bringing
• proszę can mean I ask or I’m asking

English makes a stronger distinction between simple present and present continuous. Polish usually does not.

The exact English translation depends on context. In an office or service situation, this sentence often feels like:

• I’m not only bringing the original, but I’m also asking for confirmation from the office.

Both verbs are related to carrying/bringing, but they are not used in exactly the same way.

• nieść / niosę = to carry, focusing on the act of carrying
• przynosić / przynoszę = to bring, especially to bring something to a destination / to someone

In this sentence, the speaker means they are bringing a document somewhere, not just physically carrying it around. So przynoszę is the natural choice.

Also, przynosić is the imperfective verb. Its perfective partner is:

• przynieść = to bring in a completed sense

So:

• przynoszę oryginał = I’m bringing / I bring the original
• przyniosę oryginał = I will bring the original

It is in the accusative, because it is the direct object of przynoszę.

The thing being brought is:

• oryginał = the original

For many masculine inanimate nouns in Polish, the accusative singular is the same as the nominative singular.

So:

• nominative: oryginał
• accusative: oryginał

That is why the form does not change.

If the noun were a different gender or type, you might see a visible change.

The verb prosić o means to ask for.

This is a fixed pattern:

• prosić o + accusative

So in the sentence:

• proszę o potwierdzenie

the noun potwierdzenie is in the accusative.

However, potwierdzenie is a neuter noun, and in the singular its nominative and accusative forms are the same, so you do not see a change:

• nominative: potwierdzenie
• accusative: potwierdzenie

This construction is very common:

• proszę o pomoc = I’m asking for help
• proszę o dokument = I’m asking for the document
• proszę o podpis = I’m asking for a signature

It means something like confirmation from the office or official confirmation issued by the office/authority.

Breaking it down:

• potwierdzenie = confirmation
• z urzędu = from the office / from the authority

Here urząd usually means a public office, government office, administrative office, or official institution.

So the phrase suggests that the speaker wants confirmation that comes from the office itself, not just any informal confirmation.

A useful note: z urzędu can sometimes mean ex officio / automatically by virtue of office in other contexts, but in this sentence the most natural reading is from the office.

Urzędu is the genitive singular of urząd.

That happens because the preposition z can take the genitive when it means from / out of.

So:

• urząd = nominative
• z urzędu = from the office → genitive after z

This is a very common pattern:

• z domu = from the house
• z Polski = from Poland
• z urzędu = from the office

Be careful: z can also take the instrumental in other meanings, such as with:

• z kolegą = with a friend

So the case after z depends on meaning.

Yes, it is the same verb form, from prosić.

• proszę literally means I ask
• but in real usage it can also function as a polite expression such as:
  • please
  • here you go
  • go ahead
  • come in

In this sentence, though, it clearly has its full verbal meaning:

• proszę o potwierdzenie = I ask for / I’m asking for confirmation

So this is not just the standalone polite expression; it is the actual verb with an object.

Yes. All three can mean also / too.

So these are possible:

• ale też
• ale także
• ale również

All are understandable. In many everyday contexts:

• też is very common and natural
• także can sound slightly more formal or written
• również is also common, sometimes a bit more formal or emphatic depending on context

So the original sentence sounds normal and idiomatic.

The given word order is natural and clear:

• Nie tylko przynoszę oryginał, ale też proszę o potwierdzenie z urzędu.

Polish word order is fairly flexible, but changing it can shift emphasis.

For example:

• Nie tylko oryginał przynoszę, ale też proszę o potwierdzenie z urzędu.

This puts more emphasis on oryginał, and sounds more marked.

• Proszę też o potwierdzenie z urzędu, a nie tylko przynoszę oryginał.

This changes the focus and rhythm quite a bit.

So the original version is a good neutral choice.

Yes, it sounds fairly formal or at least appropriate for an administrative context.

Reasons:

• oryginał and potwierdzenie are typical office/document words
• proszę o ... is a polite, standard way to request something
• urząd refers to an official institution

So this is the kind of sentence you might hear or say in a government office, administrative office, or when dealing with official paperwork.

It does not sound stiff or unnatural; it just fits a formal situation.

A learner often notices the nasal vowels here.

• proszę is pronounced roughly like PRO-sheh, but the final ę is often not strongly nasal in everyday speech, especially at the end of a word.
• urzędu is roughly oo-ZHEN-doo, where:
  • rz sounds like the s in measure
  • ę before d is pronounced more like en

So in normal speech:

• proszę often sounds close to proshe
• urzędu often sounds close to u-zhen-du

This is normal and does not mean the spelling is being ignored; it is just how Polish pronunciation works in context.
