jIH:
1) jaghpu'na'ma' chaH qama' 'ar'e' ? or 2) jaghpu'na'ma' chaH qama''e' 'ar ?
I rethought this matter and decided that unless there is any Ca'Non which suggests otherwise, to be placing the {-'e'} on the noun instead of the question word {'ar}. So, in the example above I'd finally choose to write {jaghpu'na'ma' chaH qama''e' 'ar ?}. First of all, there's something which seems wrong with writing {jaghpu'na'ma' chaH qama' 'ar'e' ?}. And second, the only question words in Ca'Non known to be able to bear type-5 suffixes are the {'Iv} and {nuq}, since they occupy *exactly* the same position as their answer. But (as far as I know), there is nowhere written that the {'ar} functions similarly. So, sorry {'ar}.. No type-5 suffixes for you.. ~ Qa'yIn
