TECH: PROPOSED GRAMMAR CHANGE X1: BAI afterthought connectives

[Jorge Llambias <jorge@PHYAST.PITT.EDU>]

CHANGE X1

PRESENT LANGUAGE:

BAIs and other tags can be used as forethought connectives but
not in afterthought.

PROPOSED CHANGE:

Add "tag BO" as a joik. (Essentially BAI BO can be used wherever {joi} can
be used.

RATIONALE:

The possibility of using them as connectives already exists. This would
simply allow the afterthought form to be used as well. Some of them are very
useful (and have already been used in practice) e.g. maubo, me'abo, du'ibo,
ba'ibo.

NOTE: This change is an extension. It does not affect any existing
grammatical text.
