I agree {ce'u} is somewhat related to {makau}, but I wouldn't say
they are equivalent. See below for some more on this.

I think there is a way to fix this, or at least to make it a little
more palatable. We have four types of "incomplete bridi" in Lojban,
corresponding to ma, makau, ce'u and ke'a. But none of them is really
a pure incomplete bridi, each of them carries some additional baggage
as to how the bridi is to be completed. Let's imagine that in ancient
times {ma} was the way to mark a pure incomplete bridi, and to ask a
question you had to use {mapau} (which you can still do today, of
course). Now, since pure incomplete bridi have no use on their own,
the unmarked form {ma} started to be used with the meaning of {mapau},
first as slang but eventually in mainstream usage as well. That's
why now it looks on the surface as if {makau} is a derivative of the
question {makau}, but in fact they are both, {makau} and {ma[pau]},
derivatives of the pure original {ma}. The same works for all the
other "question" words, which are not really questions but just
marks of incompleteness. Careful or very pedant speakers still say
{xupau}, {xopau}, etc. to ask questions.

{ce'u} and {ke'a} in the ancient days were {maceu'u} and {make'au},
but these forms ended up as simple KOhA because nobody used them
with other selma'o, nobody knew what to do with xuceu'u, xoke'au,
and so on.

I'm not sure I understand. Why can't we distinguish:

  1- la djan djuno le du'u xukau la djein klama
     John knows whether Jane went.

  2- xukau la djan djuno le du'u la djein klama
     Whetherever John knows that Jane went.

  3- xukau la djan djuno le du'u xukau la djein klama
     Whetherever John knows whether Jane went.

What am I missing?
