"Wrzesień to nie mój miesiąc."

Translation: September is not my month.

[Rimdus]

Well, It's MY month. :)

Does "to" force the sentence in Nominative? Everything would be genitive for me

[idanlipin]

To - nom. Jest - inst.

[Lt_Serebryakov]

In Polish, I thought the negative (nie) always came before the verb. So why isn't it Wrzesień nie to mój miesiąc?

[alik1989]

To is not a verb, but a dummy pronoun.
