I have a very straightforward, "what is this?" question: What are the bu'a bu'e bu'i bu'o bu'u thingies? I understand broda, it's like ko'a only for selbri, assigned with cei, right? Do I understand aright that bu'a is to selbri what da is to sumti (and thus that broda is to bu'a what ko'a is to da)? Or have I missed something? Just trying to keep myself straight. ~mark
