Questions & Answers about W urzędzie wypełniam formularz i wpisuję adres.
Not quite.
Urząd usually means an official, public, or government office, such as:
- a city office
- a tax office
- a registry office
Biuro is more like:
- an office as a workplace
- an office room
- a business office
So w urzędzie suggests you are in an administrative/public office, not just in someone's office at work.
Because after w meaning in / at a place, Polish normally uses the locative case.
So:
- basic form: urząd
- after w for location: w urzędzie
This is a very common pattern:
- w domu = in the house
- w sklepie = in the shop
- w urzędzie = in/at the office
The form urzędzie may look a bit irregular at first, but it is just the correct locative singular form of urząd.
