I am sure I copied it correctly.
NOT A TEACHER
Hello,
1. I found the sentence on the Web. It seems that you did, indeed, copy it correctly. It appears that the
Post accidentally (of course!) left out some words.
I think that the sentence should read:
"That would eliminate any leverage
that Europeans
had regarding the many people who had been arrested in X," he said.
In my
opinion, we should diagram it as:
Main sentence: That would eliminate any leverage
regarding the many people who had been arrested in X.
Adjective clause (it modifies "leverage"): that Europeans had. (The "that" could be deleted. Thus it appears that the
Post accidentally left out only one word -- "had.")
NOTES:
a. "regarding the many people / who had been arrested /in X" is a prepositional phrase that modifies (describes) "leverage."
i . "who had been arrested" is an adjective clause that modifies "people."
ii. "in X" is a prepositional phrase that modifies "had been arrested."
b. According to at least one of my books, "he said" is a parenthetical element that does not need diagramming.
