Re: Could anyone help me to analyse the clauses "embedded" in this sentence?
"This is what they understood the President’s testimony to be"
***** NOT A TEACHER *****
Hello, Thincat:
I have two books that explain such a sentence in two different ways. The "troublemaker" is that word "what."
Well, I always take the harder approach.
Look at this sentence from that book: "(You) do what is right."
My book says that it should be parsed as: (You) do
that which is right.
"Which is right" is an
adjective clause that modifies "that."
Therefore, the book, I presume, would parse your sentence as:
"This is that which they understood the President's testimony to be."
* "which they understood the President's testimony to be" would be an
adjective clause.

Would you like an easier analysis? OK. Here is the other book's idea.
Its sentence is: "That is not what I meant."
The book says that "what I meant" is a
noun clause. It is the subjective complement of "that."
Thus, I presume, that book would parse your sentence as:
"What they understood the President's testimony to be" is a
noun clause acting as the subjective complement of "This."
