12. Bound variable pro-sumti and pro-bridi: the da-series and the bu'a-series

The following cmavo are discussed in this section:

     da      KOhA  da-series     something-1
     de      KOhA  da-series     something-2
     di      KOhA  da-series     something-3

     bu'a    GOhA  bu'a-series   some-predicate-1
     bu'e    GOhA  bu'a-series   some-predicate-2
     bu'i    GOhA  bu'a-series   some-predicate-3

Bound variables belong to the predicate-logic part of Lojban, and are listed here for completeness only. Their semantics is explained in Chapter 16. It is worth mentioning that the Lojban translation of Example 1.2 is:

12.1)  la djan. cu lafti da poi grana ku'o gi'e desygau da
       John raised something-1 which is-a-stick and shake-did something-1.
       John picked up a stick and shook it.
