The BPFK pages for "nonce connectives" and "lerfu forming cmavo" seem to indicate that {ba'e bu} should not form a letteral.
However, "nonce connectives" also includes this example:
- ko pensi me'o depsna bu .e me'o ba'e bu
- Think about "hesitation sound", and the emphasis letter.
The parsers are also at odds: YACC and jbofihe reject {ba'e bu}, and camxes accepts it.
I assume that whatever is true for {ba'e bu} is also true for {za'e bu}, but I'm confused by the seemingly contradictory statements that {za'e} is "grammatically identical to za'e" and yet "for grammatical purposes, {za'e} binds with and marks the following word". It would seem that whatever it means to "bind" the following word, it's not a grammatically significant operation, since {ba'e} and {za'e} differ in that aspect.
