Questions & Answers about Mój brat niedawno wyjechał w delegację.
Why is the verb wyjechał and not just jechał?
The prefix wy- adds the meaning of 'out' or 'departure.' While jechał just means he was traveling or driving (an ongoing action), wyjechał specifically means he 'departed' or 'left.' Adding the prefix also makes the verb perfective, meaning the action of leaving is fully completed.
Does wyjechał tell us how he traveled?
Yes! Because it comes from the base verb jechać (to go by vehicle), we know he didn't walk. He could have driven, taken a train, or even flown. If he had left on foot, the verb would be wyszedł instead.
Why do we say w delegację? I thought trips usually use the preposition na.
That is a great observation! While you usually go na wycieczkę (on a trip) or na urlop (on vacation), a business trip is a special exception in Polish. You always go w delegację.
Why does delegację end in -ę here?
Because it is in the accusative case. When you use the preposition w to show motion toward a destination (like leaving on a trip), the noun takes the accusative. If he was already there and not moving, you would use the locative case: On jest w delegacji (He is on a business trip).
