"Whose tree is it?"

Translation: Čí je ten strom?

[Tayo571991]

Čí why does this word have so many syllables, is it supposed to be that incredibly long

[BoneheadBass]

There is a known but unresolved problem with the word čí on the Duo system side. It is not something that the Czech team can control.

It is a well known problem. Please do NOT report using the report buttons.

Is " či strom je ten? " acceptable ???

The app said it is wrong.

[VladaFu]

Posssible, but rather for: "Whose tree is that one?"

Here you have "ten strom" for "the tree"/"that tree".

Are ten and to interchangable here?

[kacenka9]

Totally

Reading this answer I was a bit surprised but I guess it just means that the following sentences are semantically equivalent:

• Čí je ten strom?
• Čí je to strom?

Still, the grammatical structure is different, right? In the first case the subject is “ten strom” (whose is (that tree)), in the second it's just “to” (literally “whose is (that one) (a tree) = whose tree is that).” After all, “ten” can modify “strom” but “to” cannot, as “strom” is masculine (inanimate).

I would appreciate a correction if I am wrong.

[VladaFu]

You are correct. The reason to accept both is that they both lead the same English translation as *"Whose is that tree." is not natural enough.

[Housamm]

Or can I say:
Či strom ten je?

[VladaFu]

incorrect
