A prophecy indeed. Now, look at all prophecies, they hint at their meaning but more often than not elude the entirety of it. Think of the words "not by the hand man well he fall" There are some possibilities to this that have been discussed already:Bucky said:OK, it's in Appendix A, the section on Gondor.....
It's Glorfindel.....
What he says, which was & is misconscrued by PJ, The Witch-king & many people on this site, is NOT that "no man can harm or kill the Witch-king" but, "Not by the hand of man will he fall".
It's simply a prophesy, not a life insurance guarentee against any encounters against men.
¤ No man of Men will bring the fall of WK
¤ No man of any Race will bring the fall of WK
With all that prefacing out of the way, I can freely state that all of the WK's power stems from the Ring that he wears, not he himself. So, as an almost most far stretched conclusion, Merry's blade bit through the armorment of the Mortal Ring to the man benieth who had fadded, causing the stretching of life to falter of him, allowing the Shield Maiden to commit the final blow.
Just my thoughts.
