Translation:My coat is in the wardrobe, in which your boots are.
- My coat is in the wardrobe, in which your boots are.
This is a quite awkward and unnatural translation into English (at least for a number of us). It may be formally correct, but nobody I know speaks like this.
A more natural translation:
- My coat is in the cupboard which your boots are in
Note the change of word order.
My answer was marked as incorrect because I used this word order.
Please don't correct my English duo - it is my native tongue - I want to speak Hungarian better!
