Yes, strikes me that "Whose telephone is this" and "Whose is this telephone" are interchangeable. So both should be correct. A bit pedantic.
Whose is this telephone should be OK
whose is this telephone?
Can you use "телефон" to refer to a cellphone?
Exactly, or you can say 'мобільний' or 'мобільний телефон'.
a cellphone is mobil'ka
Mh I typed in "whose telephone is that" because you could say "this" or "that" in earlier cases for це. But here, it's wrong?
Actually you can use it here without changing the sense.
But usually "that" is translated as "то" and "this" is translated as "це".
Can you say whose telephone is this?
I meant - whose is this telephone
Would „Чий телефон це?” work also?
Можна і так.
have problem to pronounce чий and це. Have tried in google translator many times, never success.
quest foг чий like for why por question
