In the refgram, bo- is shown to turn transitive verbs into new transitive verbs:

However, Hoemaı has since suggested[1] that it might be better for bo- to move the direct object to the front and delete the old subject entirely.
bọcho

This means we can no longer use bộtua and bộtao as agent tags, and so we must use a new word (like ecı).
Shua múao êcı jí.
The tree falls, caused by me.

bọcho
___ is/gets liked (by someone).
bọdo
___ is/gets given (to someone by someone).
