Yesterday night I was thinking of the Noldorin word _nad_ 'thing'
(Etym. s.v. NÂ2-) and it came to me that it could be a gerund form
of a verb *_na-_ 'to be': thus *'being' > 'thing'. What do you think?
[I think such a form might have come to be interpreted as a gerund,
though the fact that it is clearly cognate with Q _nat_ 'thing' (same
entry), which looks rather like an extended, nominalized formation
than a Qenya gerund, suggests that N _nad_ was probably not
gerundial in origin. Note the somewhat similar Quenya word _eala_
'being, spirit', apparently a participial formation in _-la_ <
_ea_ 'to be, exist' (X:165). CFH]
