Questions & Answers about Szukamy łazienki, w której jest nowa wanna.
Why do we use w której here instead of w którym?
The pronoun refers back to łazienka (bathroom), which is a feminine noun. Because it follows the preposition w (in) to show location, it needs the Locative case. The feminine Locative form of który is której.
Why is the word for bathroom łazienki instead of the basic form łazienka or the direct object form łazienkę?
The verb szukać (to look for) always forces its object into the Genitive case. Even though the bathroom is the thing we are looking for, we must use the Genitive form łazienki instead of the Accusative.
Why is nowa wanna in the basic Nominative case?
In the second part of the sentence (w której jest nowa wanna), the "new bathtub" is the subject. It is the thing that exists inside the bathroom. Subjects always take the basic Nominative case.
Is the comma before w której mandatory?
Yes! In Polish, you must always put a comma before relative pronouns like który or której when they introduce a new part of the sentence.
