9. sumti and bridi questions: ``ma'' and ``mo''

The following cmavo are discussed in this section:

   ma  KOhA            sumti question
    mo  GOhA            bridi question
Lojban questions are more fully explained in
Chapter 19, but ``ma'' and ``mo'' are listed in this chapter for completeness. The cmavo ``ma'' asks for a sumti to make the bridi true:
9.1)  do klama ma
    You go to-what-destination?
    Where are you going?
The cmavo ``mo'', on the other hand, asks for a selbri which makes the question bridi true. If the answer is a full bridi, then the arguments of the answer override the arguments in the question, in the same manner as the go'i-series cmavo. A simple example is:
9.2)  do mo
    What predicate is true as applied to you?
    How are you?
    What are you doing?
    What are you?
Example 9.3 is a truly pregnant question that will have several meanings depending on context.

(One thing it probably does not mean is ``Who are you?'' in the sense ``What is your name/identity?'', which is better expressed by:

9.3)  ma cmene do
    What sumti is-the-name-of you?
    What is your name?
or even
9.4)  doi ma
    O [what sumti?]
which uses the vocative ``doi'' to address someone, and simultaneously asks who the someone is.)

A further example of ``mo'':

9.5)  lo mo prenu cu darxi do
        .i barda
    A [what selbri?] type-of person hit you?
        (Observative:) A big thing.
    Which person hit you?  The big one.
When ``ma'' or ``mo'' is repeated, multiple questions are being asked simultaneously:

9.6)  ma djuno ma
    [what sumti] knows [what sumti]?
    Who knows what?
