What case is apples in?
In this sentence it is a subject of the sentence - so nominative (plural)
Why not smaczna?
'smaczna' is singular feminine.
'jabłka' is 'not masculine-personal' plural. The 'not masculine-personal' form of the adjective in Nominative is identical to neuter singular. So "smaczne".
When I answered są the last time this question came up, it corrected to 'to'. Now it's opposite.
why we put są? what does it mean?
"są" is plural form of "jest" , and they usually mean "they are" .
We think that "pyszne" = "delicious" and is stronger than just "tasty", but there were so many reports for "delicious" that we decided to give up on this distinction.
Why is it jabłka and not jabłek
Apples are simply the subject of the sentence here, so they take Nominative, which is "jabłka". "jabłek" is Genitive and makes absolutely no sense here.
I thought plural will be SmacznY
The only time I've ever used smaczny (up to this point of the lesseons) is when it is describing something singular and masculine.
Why not "Jabłka są smacznymi/smacznymy" in instrumental?
Thank you. I will check the article out.
