It's not really "before the verb" but instead "after something else".
Basically, it can be put after other words that you are asking after.
It could also be "Elmayı mı siz yiyorsunuz?", I think, if you want to ask, "Are you eating THE APPLE?" / "Is it the apple that you are eating?"
Thank you very much for explaining that! Çok teşekkür ederim açıklanız için!
You’re right, someone should really edit the ‘Tips and notes’ for this unit (‘Questions - 2’):
‘The personal endings for the to be copula are always attached to this particle. They are never kept on the end of the verb or noun that they would normally attach to in declarative sentences. ’
This contradicts what you have said...
Can someone please clear up my confusion? The tips say 'The personal endings for the to be copula are always attached to this particle. They are never kept on the end of the verb or noun that they would normally attach to in declarative sentences.'
Doesn't this sentence contradict that? I don't understand. Is it an exception? Is the sentence wrong? Are the tips mistaken or incomplete?
Doesn't this sentence contradict that?
No, it doesn't.
There is no copula in this sentence.
This is not a "I am a boy" sentence or "I am happy" with a copula connecting the subject to a noun or adjective.
In this sentence, "are" in "are eating" is a helping verb that English needs to form the present continuous aspect. In Turkish, it corresponds to the -yor- suffix.
