Whose cat is this? or Whose is this cat?
Which one is correct?
The first one without a doubt !
Whose is this cat?... that sounds like a direct translation from Portuguese, don't you think? Like, if you were about to translate that, like "De quem" ! I don't remember ever seeing anywhere that the second sentence is wrong, but... really, it doesn't sound that common. Definitely, to be on the safe side I would say, go for the first one!
Ouch... from a Brit, hearing from someone else that a common way we speak sounds 'off' is quite... disheartening.
Both are grammatically correct.
Whose cat is this? whose= possessive determiner
Whose is this cat? whose = pronoun
As a native speaker, I prefer Whose cat is this? The second sentence sounds awkward, especially based on how it sounds - pronunciation wise...too many "s's" in a row.
