I put "Dziś to najkrótszy dzień w roku". Is that wrong?
yes, because in sentences like this "dziś" is adverb
Thanks. I'm always so keen to avoid using the instrumental case that I didn't realise it wasn't necessary here.
it would be incorrect to use instrumental here, as "Najkrótszy dzień w roku " is a technically a subject.
Would it? That's what I wss wondering. Is Polish flexible lile that? Sometimes when I expect the instrumental case mianownik (is that the nominative?) shows up. It really confuses me.
Check here: https://www.duolingo.com/comment/16373167 - Part 5.
Dziś jest najkrótszy dzień roku.
Is this Ok to omit w?
Yes, it's either "in the year" (w roku) or "of the year" (roku), but those two mean basically the same here. Both are accepted.
Thank you very much~ gururu~
