"This lady is not in our group."
Translation:Ta pani nie jest w naszej grupie.
Is the noun phrase 'our group/naszej grupie' in dative or genitive, and why?
I think it's locative just like the sentence about the restaurant I replied to earlier :) Whenever something is IN something, it's locative, for example:
- in the bank = w banku
- in the park = w parku
- in the water = w wodzie
- in the garden = w ogrodzie
- in your head = w Twojej głowie
- in your dreams = w Twoich snach
In a way, "dama" is even a better translation... it's just that 'pani' is hard to translate. It's something between 'woman' and 'lady', it's not exactly any of those...
