What is the correct form?

"Какая модель это?"


"Какой модель это?"

I'm quite sure that the correct form is "Какой модель это?" but google translate - translate "which model is it" into "Какая модель это?" and I'm afraid maybe I'm not right.

  • while the "is" verb is omitted in Russian, the place it could take somewhat gaps, so it naturally gets filled with some other word - or small pause. Here "это" put in the position of the missing verb would make the phrase sound smooth and natural.

  • While only "какая модель это" is correct, you might hear something like "какой модели (gen.) это" which has generally the same meaning.

модель is a feminine noun (IIIrd declension, f words ending with -ь) so the right adjective would be какая as it goes with модель.

  • I always thought that the word model is masculine noun. My mistake.

  • That's right, even male models are feminine in Russian: Он рабо́тает моде́лью (He works as a model). Commented Jun 7, 2017 at 6:33
