Why can't you say Ta kobieta to wspaniala aktorka?
Why is it sometimes when I use "Ta" Kobieta....... Duolingo will tell me the alternative would be Kobieta....... I use "Ta" I get zinged. I don't use "Ta" I still get zinged.
"ta" is the feminine singular word for "this" (this woman). It's definitely needed here, I would need to know what the other sentences were to say what could have happened there.
How do I know if this sentence takes the case: instrumental?
A sentence built as "[noun phrase] is [noun phrase]" is translated either as "[Nominative] to [Nominative]" or "[Nominative] jest [Instrumental]".
