I have seen some people use the sentence “what is the mind is being debated widely” instead of “what the mind is is being debated widely”.
Their reason is that “what is the mind” is a clause like “A is B”, so it can be used that way.
Is it correct? If so, is the first sentence below as grammatically correct as the second one, which is constructed in a usual form?
- He tries to explain what the mind is.
- He tries to explain what is the mind.
