It obviously returns a function adding n to the function's parameter,
n being bound into the functions's closure during the call to ADDN. 
It's simple and straightforward.

Actually, this suffices:

    (defun addn (n)
      (lambda (x)
        (+ x n)))

And Lisp's "macro language" isn't involved at all here.
