Questions & Answers about W tej piaskownicy dobrze się bawi, bo piasek jest suchy i ciepły.
Why is it w tej piaskownicy and not w ta piaskownica?
Because w here means in, and after w Polish normally uses the locative case for location.
So:
- dictionary form: ta piaskownica = this sandbox
- after w: w tej piaskownicy = in this sandbox
Both words change form:
- ta → tej
- piaskownica → piaskownicy
They both have to match in case, gender, and number.
What case is piaskownicy?
It is locative singular.
Why?
- the preposition w often takes the locative when it means in/inside
- piaskownica is a feminine singular noun
- its locative singular form is piaskownicy
So:
- piaskownica = nominative
- piaskownicy = locative
Why is it tej? What form is that?
