You clearly know very little about English grammar, as is evident from the fact that you don't even know the difference between a noun phrase and a clause!
I'd explain why you're wrong, but judging by the above and your past replies on this site, I doubt if you'd understand a word I said.
The only accurate bit in your reply is that Otto Jesperson was responsible for the term 'content clause'. Note that he could have, but didn't, use the term 'noun clause', a misnomer if ever there was one.
