Yay, one more experimental word in the discussion.
Ilmen even explained it on IRC as lu .i zo na'ei smuni simsa zo na li'u
To me it seems to be much closer to {to'e} than {na} though..
Could you explain the problem this proposed word solves and
the difference to {na} and {to'e} (in the best case by example)?
Otherwise I don't get what you are trying to say.
According to what xorxes said in bpfk group {na'e} is the same as {na} but with a different scope. The author of {na'ei} thought otherwise.
{na} and {na'ei} differ in that {na} (supposedly, at least in Wave lessons) negates everything to the right of the bridi. na'ei negates only the selbri following it.
Tanru aside, {na'ei} exists in FOPL. It makes a predicate which holds true for its arguments iff the original holds false for its arguments. It's in NAhE but is not really all that semantically similar to the other NAhE. It is also essentially the same as a {naku} at the *end* of a bridi.
