I doubt 'hand' is involved in Boromir however. Ruth Noel seems to be confusing, for example, -bor in Celebrimbor (which name contains paur 'fist, tightly closed hand') with the initial part of Boromir. I would guess 'jewel' is involved.

In Appendix F Boromir is said to be a 'mixed form'.

I agree with the point regarding conversational Elvish brought up by Mr. Hicklin. I highly recommend Carl Hostetter's article Elvish as She Is Spoke over at E. L. F. for anyone interested.
