that works well after the noun

[GoldfishLord]

I wonder if it's relevant to the question whether that is a relative pronoun that that works well after the noun way in a certain type of relative clause in which which seems totally ungrammatical:

I'd like to know if the blue part is the noun complement clause of the red part.

 

[Charlie Bernstein]

That makes sense. If I were diagramming it, that's how I'd show it — by linking the blue clause to "the question."

But I'm no grammarian. Let's see what others say.
