I recently learned about parenthetical expressions, and I just want to know if these following phrases are the ones.
I took notes, the elements of the story.
And in this one.
Victims of cancer or car accidents, once they heard my story, they hobbled and wheeled over to see me, they and their families, though none of them spoke English.
Just to be on the safe side, the phrases that are italicized are what I assume to be parenthetical phrases. "The elements of the story," and "They and their families."
In the first sentence, it seemed to me that the type of this parenthetical phrase is appositive. But I am not so sure about this. Is it appostive phrase or not?
And about the second sentence: I am just totally confused and not even sure if it is a parenthetical phrase or not. Also, I am not sure why it's "they" instead of "them". If you will tell me what it is, I will be deeply glad to receive the answer.
