But {na'eca'a} parses, and in fact {na'epu'i} is even in the cmavo list.
CAhA is just glaringly different from other tense cmavo in the way it's
negated, though. People _do_ say {ka'enai}, when {na'eka'e} would be the
grammatical version.

Okay. I'm willing to accept that this system is more powerful, but is
there any document which explains how this power should be _used_? The
Book rarely uses more than two tenses at a time, so it doesn't give much
of an indication of how they interact.

Also, I know from other situations like (as you point out) numbers, and
UI, that meaningless conglomerations of words can be grammatical. It's
not the grammar's job to restrict semantics.

How does this justify VA and ZI being separate? And do they in fact have
different grammar, or is this another case of a bogus split in selma'o?
(I forget what the other one was - I think it involved TAhE)
