Questions & Answers about Czy twój brat pracuje w biurze?
Why does the word for office change from biuro to biurze?
Because it follows the preposition w (in), which requires the Locative case when describing a location. For neuter nouns ending in -o like biuro, we drop the -o and add -e. However, adding -e causes the consonant r to mutate into rz, giving us biurze.
Why do we use the preposition w instead of na here?
We use w (in/inside) because an office is an enclosed physical space or a room. You use na (on/at) for open spaces, events, or certain traditional institutions like the post office (na poczcie). For a standard workplace room like an office, w is the correct choice.
Why is it twój and not twoja or twoje?
The word twój means 'your' and it must match the gender of the noun it describes. Since brat (brother) is a masculine noun, we use the masculine form twój. If you were asking about a sister, you would use the feminine form: twoja siostra.
The dictionary form of the verb 'to work' is pracować. Why does it change to pracuje here?
Verbs ending in -ować have a special pattern. When you conjugate them, the -ow- part is replaced by -uj-. Then you add the ending for the he/she/it form, which is -e. So pracować becomes pracuje to match twój brat (he).
