A new Saxnot etymology

Carla O'Harris, over on the Rydberg discussion list, put forth this
interesting possibility:

Sax = sword
Not: to which Cleasby/Vigfusson give the Old Icelandic as "NAUÐ, f.
[Ulf. nauþs = GREEK; A.S. neôd; Engl. need; Hel. nôd; O.H.G. nôt;
Germ. noth; Dan. nöd] :-- need, difficulty, distress;"

Which would derive from the PIE root *nau(1)- 'death, to be
exhausted' .. hence lacking, in need of.

Thus "Sword-need"
IF this were correct, it would suggest that Turville-Petre was right
in associating Saxnot with Frey (who lost/traded away his enchanted
sword) rather than Tyr.


Two questions:
1) In terms of mythic issues, it fits; but does this seem
linguistically correct?


2) Because people like Puhvel have tried to connect Saxnot with Sax-
Nuada ... Is there any way *nau(1)- might produce the Celtic "Nodens"
and "Nuada"?


As always, many thanks!
