"Whose mirror is this?"

Translation: Czyje to lustro?

[stephenpeckhover]

Once I wrote "Czyje lustro jest tej", and another time I wrote "Czyje jest tej lustro". But I don't know why they were wrong. Thoughts, anyone?

Are there multiple ways of writing this?

[4d1n]

Second possible answer is "Czyje jest to lustro?".

You can't use "tej", lustro is neuter and has to be followed by "to" in correct case. "Tej" is a feminine form of "this" in genitive, dative and locative.

i answered : "Czyje jest to lustro?" and it was written as incorrect

[Aug.Girotto]

Can i say "czyje jest to lustro" too?
