Recently, I saw in a sentence written by an expert the {-be'} used on {-lu'}.I won't say who wrote it, nor will I quote the exact sentence, since these details are of no importance.Suffice it to say, that it was on a transitive verb (not that if the verb was intransitive, it would make any difference).So, I was wondering how on earth, this sentence could be correct.If I wrote {Soplu'be'}, then what would this mean ? "not someone unspecified eats" ? And if I want to say "not someone unspecified eats", then why not just write {Sop (subject)} ?
