Questions & Answers about Proszę o kolejną kopię dokumentu.

What does proszę mean here exactly?

Here proszę means something like I am asking for or, in natural English, please in a polite request.

The verb is prosić = to ask / to request.
So Proszę o... literally means I ask for....

This is a very common polite pattern in Polish:

• Proszę o pomoc. = Please help / I am asking for help.
• Proszę o rachunek. = The bill, please.

So in this sentence, proszę is not just a standalone please — it is part of the request structure proszę o + noun.

Why is there an o after proszę?

Because the Polish verb pattern here is:

prosić o + accusative

That means to ask for something.

So:

• prosić o kawę = to ask for coffee
• prosić o dokument = to ask for a document

In your sentence:

• o kolejną kopię dokumentu

The preposition o is required by this meaning of prosić.

Be careful: o can mean different things in other contexts, but here it is simply part of the expression prosić o = to ask for.

Why is it kolejną and not kolejna?
