I think I have problems with this topic.
Which sentences are correct?
Who could be this guy? - seems correct to me
Who could this guy be?
Could this sentence be correct? - seems correct to me
Could be this sentence correct?
Are there some "special" exceptions about "could + be"?
Could this sentence be correct?These are correct.
Who could be this guy? This could be correct if we are asking who could portray the guy, in a film or play etc.
The "could be correct" in my sentence above, is offering a possibility of correctness. In the same way, this could be correct: (It) Could be (that) this sentence is correct.
