Questions & Answers about W naszej rodzinie pomagamy sobie nawzajem.
Because after w meaning in, Polish uses the locative case for location.
- rodzina = nominative singular, the dictionary form
- rodzinie = locative singular
So:
- rodzina = family
- w rodzinie = in the family
The adjective has to match too, so nasza changes to naszej.
Naszej is the feminine singular locative form of nasza (our).
It matches rodzinie, because adjectives in Polish agree with the noun in:
- gender
- number
- case
Since rodzina is:
- feminine
- singular
- here in the locative
the correct form is naszej.
So:
- nasza rodzina = our family
- w naszej rodzinie = in our family
