Urzędniczka prosi o dowód, bo chce sprawdzić moje nazwisko.

Urzędniczka means female clerk, female office worker, or female official.

The ending -ka often marks a feminine noun in Polish. The masculine form is urzędnik. So:

• urzędnik = male clerk/official
• urzędniczka = female clerk/official

In this sentence, the speaker is specifically referring to a woman.

Prosić is the infinitive, meaning to ask or to request.

In the sentence, we need a conjugated form because the action is being done by urzędniczka.
So prosi is the 3rd person singular form:

• ja proszę = I ask
• ty prosisz = you ask
• on/ona prosi = he/she asks

So Urzędniczka prosi... means The clerk asks...

The verb prosić o means to ask for.

So:

• prosić = to ask
• prosić o coś = to ask for something

That is why the sentence uses o dowód:
Urzędniczka prosi o dowód = The clerk asks for an ID/document

After o in this meaning, Polish normally uses the accusative case.

In everyday Polish, dowód can mean a few things depending on context:

• proof
• evidence
• ID card / identification document

In this sentence, because a clerk wants to check the speaker’s surname, dowód most naturally means ID or identity document, often specifically dowód osobisty (identity card).

So here prosi o dowód is best understood as asks for ID.

Good question. After prosić o, the noun should be in the accusative. But some masculine nouns have the same form in the nominative and accusative.

Here:

• nominative: dowód
• accusative: dowód

So the case is changing grammatically, but the word form happens to stay the same.

Bo means because.

It is very common in spoken and everyday written Polish. It is natural and normal, but less formal than words like:

• ponieważ = because
• gdyż = because/since

So:

• bo chce sprawdzić moje nazwisko = because she wants to check my surname

This sentence sounds natural and everyday, not stiff or overly formal.

Chcieć is the infinitive, meaning to want.

In the sentence, it must be conjugated because it refers to she:

• ja chcę = I want
• ty chcesz = you want
• on/ona chce = he/she wants

So bo chce sprawdzić... means because she wants to check...

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

• sprawdzać = imperfective, to be checking / to check repeatedly
• sprawdzić = perfective, to check / to verify completely

After chce, using sprawdzić suggests a single completed action: she wants to verify the surname.

So:

• chce sprawdzić moje nazwisko = she wants to check my surname

If you used sprawdzać, it would sound more like focusing on the process or repeated checking, which is less natural here.

Because nazwisko is a neuter noun.

Polish possessive forms agree with the gender of the noun:

• mój = masculine
• moja = feminine
• moje = neuter

So:

• mój paszport = my passport
• moja karta = my card
• moje nazwisko = my surname

That is why moje is correct.

Because nazwisko is neuter, and in this sentence it is the direct object of sprawdzić, so it is in the accusative. For neuter singular nouns, the nominative and accusative are usually the same.

So:

• nominative: nazwisko
• accusative: nazwisko

And moje also has the same nominative/accusative neuter singular form.

• nazwisko = surname / last name
• imię = first name / given name

So if someone wants to verify your family name, they check your nazwisko, not your imię.

Examples:

• Mam na imię Jan. = My first name is Jan.
• Moje nazwisko to Kowalski. = My surname is Kowalski.

Yes. Polish word order is more flexible than English because case endings show grammatical relationships.

The basic sentence:

• Urzędniczka prosi o dowód, bo chce sprawdzić moje nazwisko.

Possible variations are possible, for example to shift emphasis:

• Bo chce sprawdzić moje nazwisko, urzędniczka prosi o dowód.
• Urzędniczka chce sprawdzić moje nazwisko, więc prosi o dowód.

But the original version is the most neutral and natural.

Because Polish often leaves out subject pronouns when they are clear from the verb form or context.

In English you must say she wants.
In Polish, chce already tells you it is he/she/it wants, and here the context clearly refers back to urzędniczka.

So Polish commonly says:

• bo chce sprawdzić moje nazwisko

instead of:

• bo ona chce sprawdzić moje nazwisko

Adding ona is possible, but usually unnecessary unless you want extra emphasis.

A rough pronunciation is:

oo-ZHEND-nich-ka

A few useful points:

• rz is pronounced like the s in measure or zh
• ę is a nasal vowel; before some consonants it may sound a bit like en
• czk in -niczka is a tight consonant cluster, approximately nich-ka or nich-tsh-ka depending on how carefully it is pronounced

You do not need to pronounce it perfectly right away, but the main stress is on the second-to-last syllable:

urzęd-NICZ-ka
