>... I can't even think what {-lu'be'} would mean.
{-lu'} is an indefinite subject, and can usually be translated using the
impersonal "one" in English. I can understand {-lu'be'} as referring to
sort of an impersonal "noone".
{Supbe'lu'} and {Supbe' vay'} have related meanings.
I think {Suplu'be'} and {Sup pagh} are related in a similar way.
