As far as I'm concerned, the questions after all this are simply these two:
1. If we want to talk about leaving a place which is considered to be
a starting point, then does the starting point which has been marked
by the {-vo'} need to be the object of the verb or not? Do we say
{juHvo' vImejpu'} or {juHvo' jImejpu'}?
I'll ask Dr. Okrand to clarify this, since it might affect the final version of the lines with {mej} in the 2nd edition of the paq'batlh.
2. Does the info which regards {mej} and its' use with {-vo'} apply
for {tlhej} as well?
