What is the hint to this question?
Well clearly:
"What" is the answer to this question!
because:
"What" is the title, the first clue, the second, and indeed the hint.
Just a guess:
What is the answer to this question?
They're "What is the title to this question?", "What is the first clue to this question?", "What is the second clue to this question?", and "What is the hint to this question?", respectively.
I've had another thought. This time I'm going with:
A question!
because:
The title is a question, the first clue is a question, the second clue is a question, and also the hint is a question.
