BPFK Section: Grammatical Pro-sumti
Well, since I think that {du'u} and {ka} are two entirely different things — though related more or less as a proposition is to an event, my view may not be worth much. The problem seems to be that we have two conventions about empty places in abstractions; filled with {ce'u} or filled with {zo'e}. For the first place, we have decised that the unfilled space is {ce'u}, but when that space is filled already we are left with what to do with the first unfilled space. Appparently what has been worked out is that in {ka} the first unfilled space is {ce'u} but in {du'u} all unfilled spaces are {zo'e} (or have it got that backward?), i.e., every {ce'u} must be explicit. Then the question is, does {ke'a} follow the rule for {ce'u} in {ka} or the rule that it can be omitted in the first place only. The answer seems to be that it follows the {ks} {ce'u} rule, omission in the first empty place — though xod does not like this in spite of usage. Personally, I would go for either that
rule or the {du'u} {ce'u} rule thoughout.

If there's anything I need to understand in:

which appears to have mostly been written by xod, someone please explain it to me.
