W urzędzie czekamy przy małym okienku.

W urzędzie means in the office / at the office. After w when it means location, Polish normally uses the locative case.

• dictionary form: urząd = office, public office
• locative singular: urzędzie

So:

• urząd → w urzędzie

This is why it is not w urząd.

Polish usually does not need subject pronouns, because the verb ending already shows who is doing the action.

• czekam = I wait
• czekasz = you wait
• czekamy = we wait

So czekamy already means we are waiting.
You could say my czekamy, but that would usually add emphasis, like we are the ones waiting.

It can mean both, depending on context.

In Polish, the present tense often covers both:

• we wait
• we are waiting

So czekamy can describe a general action or something happening right now. In this sentence, it most naturally means we are waiting.

Przy usually means by, next to, at, or near. In this sentence, it means something like:

• at the small window
• by the small window
• next to the small service window

Very importantly, przy requires the locative case.

So:

• małe okienko = a small window
• przy małym okienku = at/by the small window

Not necessarily. Okienko is the diminutive of okno (window), so literally it means small window. But in places like offices, stations, or banks, okienko often means a service window, counter window, or ticket window.

So in W urzędzie czekamy przy małym okienku, it probably refers to the kind of little window where you speak to a clerk.

Both words are in the locative singular, because they depend on przy.

Base forms:

• małe = small
• okienko = little window / service window

Locative singular:

• małym
• okienku

So:

• przy małym okienku

The adjective must match the noun in gender, number, and case. Since okienko is neuter singular, the adjective changes to the matching locative form.

Because the noun here is okienko, not okno.

These are two different nouns:

• okno = window
• okienko = little window / service window

Their locative forms are different:

• w oknie = in the window
• przy okienku = at the service window

So okienku is correct because the actual noun used is okienko.

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

The neutral sentence is:

• W urzędzie czekamy przy małym okienku.

But you could also say:

• Czekamy w urzędzie przy małym okienku.
• Przy małym okienku czekamy w urzędzie.

These alternatives may sound slightly different in emphasis, but the basic meaning stays the same. The original version sounds natural and straightforward.

It can correspond to either in English, depending on context.

Polish w literally means in, so w urzędzie is literally in the office. But in natural English, at the office may sometimes sound better.

Because the meaning has already been given to the learner, the main point is grammatical: w + locative for location.

Yes. Czekać often takes na + accusative when you are waiting for someone or something.

For example:

• Czekam na autobus. = I am waiting for the bus.
• Czekamy na urzędnika. = We are waiting for the clerk/official.

But in your sentence, there is no object introduced with na. Instead, the sentence tells us where we are waiting:

• w urzędzie
• przy małym okienku

Usually, yes. Urząd often means a government office, public office, or administrative office, not just any workplace office.

So W urzędzie suggests a place like:

• a city office
• tax office
• registration office
• another official public institution

That is also why okienko fits well here, since many public offices have service windows or counters.

A few parts may be tricky:

• urzędzie: the rz sounds like ż, and dz is its own consonant sound
• czekamy: cz sounds roughly like ch in chop
• przy: rz again sounds like ż
• małym: the ł sounds like English w
• okienku: the ki is softened a bit before e

A rough English-style approximation could be:

• v oo-ZHEN-djye che-KA-my pshee MAH-wim o-KYEN-koo

That is only approximate, but it may help with the main sound patterns.

Sometimes, but the meaning would shift a little.

• przy małym okienku = at/by the small service window
• obok małego okienka = next to the small window

Przy suggests being positioned right there, possibly using it or waiting at it.
Obok means more strictly beside or next to, and it takes the genitive, not the locative.

So przy małym okienku is the more natural choice for waiting at the window/counter.
