Hi everybody,

I was watching inspector frost and he had a bunch of keys. He tried all the keys in keyholes, except for one. Suddenly he said: ‘I wonder what this key fits?’ is that correct, or should it be: 'I wonder what fits this key?

Are the following sentences correct:

  • What fits this key? or do you have to use ‘do’: ‘What does this key fit?’
  • Does this key fit the keyhole of the front door?’

Thanks
Alexandro

‘I wonder what this key fits’ is correct.
The key fits into a keyhole and not the other way around.

‘What does this key fit?’ / ‘Does this key fit the keyhole?’ are also correct.
