janāra
This is either the singular form of the attribute annāra, which means everything that is, or a nominalized form of the modifier nāra, which means all of, the whole of. It is more likely the latter, as it means complete thing, whole thing.
Sentence #12:
tere jañūna janāra mo rirōña ē rā jāxīsse hūta pēxa ē rā jāxīsse tēsa pēxa;
You saw complete straightness to the horizon far to the right and to the horizon far to the left.
