Questions & Answers about Rzecznik czyta komunikat, w którym przeprasza za niedogodności.
Why do we use za here, and what case follows it?
The verb przepraszać (to apologize) requires the preposition za plus the Accusative case to express the reason for the apology. This is a set phrase you will see often: przepraszać za coś (to apologize for something).
Is niedogodności really in the Accusative case? It ends in -i.
Yes, it is plural Accusative. The singular base word is niedogodność (inconvenience), which is one of those feminine nouns ending in a soft consonant. For this group of nouns, the plural Nominative and Accusative forms both end in -i. So the spokesperson is literally apologizing for 'inconveniences' in the plural.
Why does the sentence say w którym instead of just który?
W którym (in which) links the two parts of the sentence together. The relative pronoun który acts like an adjective matching the masculine noun komunikat (statement). Because the spokesperson is apologizing inside that statement, we use the preposition w (in), which forces który into the Locative case: w którym.
Why doesn't the second part of the sentence say w którym on przeprasza?
Polish frequently drops subject pronouns like on (he) when it is already obvious who is doing the action. Since rzecznik (the spokesperson) is the subject of the first clause, it carries over naturally to the second verb, przeprasza.
