Gosh... funny how you have to break up one sentence into two parts to try to explain something you obviously have wrong.
" Neither slavery nor involuntary servitude, except as a punishment for crime whereof the party shall have been duly convicted, shall exist within the United States, or any place subject to their jurisdiction."
What this means, Kowkow, in English (not your strong point) is there are TWO conditions being addresses,(one) slavery and (two) involuntary servitude.
I'd suggest you get help from the forum but it seems the majority don't know what "monarchy" means either, even after the definition has be posted many dozens of times.
You are so easy to wind up.
