Here's a direct question.
Where does he live?
And here's an indirect one.
Do you know where he lives?
I wonder how you would analyze the following structure. Can we call it "a split indirect question/noun clause"?
Where do you think he lives?

Where do you think he lives?
In Do you know where he lives?, the subclause where he lives? is called an indirect question because (a) it is an interrogative clause but (b) it is not directly put to someone. So, just to be clear, it is not the question Do you know where he lives? that is the indirect question, it is specifically the subclause.
Where do you think he lives? is a direct question (in the sense that it is directly put to someone) which happens to be complex syntactically (i.e., consist of a matrix clause with predicate think and a subordinate clause with predicate live). The Wh-element has been moved from the subordinate to the matrix clause, but this is entirely separate from the direct–indirect question type.
