I tried to find this on the Internet, too, but I was apparently too stupid to formulate a correct query in the search engine...

Re: Why is `nreverse' called `nreverse'?
The N- prefix for destructive functions is indeed present in Common Lisp, but it goes further back than that. It is so in Maclisp, which both Common Lisp and GNU Emacs Lisp have taken a lot from. (If it also existed in lisps prior to Maclisp I don't know.) Pitman's "The Revised Maclisp Manual" doesn't explain the N-. I guess it may have come from NCONC.

Why is `nreverse' called `nreverse'?
Hi all, I know that the "n-" prefix means that it is destructive. But why "n-"? I also know that this comes from Common Lisp, but still -- why the letter "n-"? TIA, -- Marcin Borkowski http://mbork.pl --- via emacs-tangents mailing list (https://lists.gnu.org/mailman/listinfo/emacs-tangents)
