Why isn't this "to jest ostatnim razem"? In noun-is-noun constructions, doesn't one of them have to be in instrumental case?
"To" in a sentence means nominative. more on that https://www.duolingo.com/comment/16373167 part four
Thanks so much!
'Ostatnia chwila'? 'Ostatnia pora'?
Only "ostatni raz" works here, since the other forms refer to a period of time, whereas "raz" refers to a single case or instant. Translates to "fois" in French (and not "temps") or "mal" un German (and not "Zeit"), if that helps.
And раз in Russian instead of время, vez in Spanish instead of tiempo ;)
