I wrote it is A fish, that should be correct no?
no, then it would read "se on kala". kalaa is the partitive form so it has to be just fish without any articles.
Thanks guys, I should read the lecture more carefully!! Best, W.
No. The partitive case ending for the noun indicates that we're talking about "some fish" rather than "one fish".
I did the same and was furious that my answer wss not submitted.
Its a shame no one can explain it beforehand
