I used the wrong language in my 1st post in this thread. I used the word "generic".

I'd like to change that to 'complicated and vast'. I'm going to read more but this stuff is so complicated I may never understand.

Anyway, I used the word generic in the sense that the words had no specific meaning. They don't, because I just don't have a good understanding of what this stuff means.

I'll keep trying and thanks for the links. I'll start by trying to understand 'some of it'.
