Verbal Derivation Implication
When a perlative noun is derived into an action verb, it denotes a movement which begins outside of the root on one side, and which ends outside of the root on another side (typically its opposite side). This can usually be conceptually translated into English as go through. The manner of this motion is either contextual (and therefore left unmentioned), or else elaborated through additional words or phrases.
If the thing doing the motion is wider, or taller, or heavier than the thing being moved through, then the perlative verb may take on the contextual connotation of severing something in two, or otherwise dismembering something.
The bird [went] through the tree by way of the hole.
The bird [[went]] through the hole [in] the tree.
(Lit: Bird‘treethroughed holebywayof)
The arrow [went] through me.
The arrow [pierced] me (and it came out the other side).
The knife will [go] through the plant.
The knife will [cut] the plant [in half].
She [went] through the wall.
It is important to note that this case has the very specific connotation that the motion both begins and ends outside of the root. It might be better to think of this case as meaning something closer to penetrate all the way through, which means that you cannot use this case to say something like tilu‘sjeivaltihõn (*birds fly through the sky). If you tried to say tilu’sjeivaltihõn, it would be like saying birds fly straight up into the sky until they penetrate the Firmament… if you believe in the concept of the Firmament in the first place. One could probably find some circumstantial reasons to say something like this (see examples below), but the point is that saying something “goes through the sky” (or something else of the like) does not elicit the same mental image in Duojjin that it does in English. You also could not use this case to say something like juri‘juttaeltihõn (*fish swim through the water). You know how fish jump out of the water for brief moments before splashing back into it? Well, imagine if that were all backwards, and a flying fish jumped into water for a brief moment before splashing back out of it… except the water it’s jumping into is shaped like a window pane, so it’s actually jumping *through* the water… If you can wrap your head around that mental image, then you might have an idea as to why the perlative case is not to be used this way, because this is the image which would be elicited by this kind of use. One would want to use the inessive case for this (Tilu‘sjeivavalõhõn/Juri‘juttavalõhõn).
Superman [[[flew]]] through the sky (and into outer space).
The ship will [go] through the sky (and emerge in outer space).
When a perlative noun is derived into a stative verb, it becomes copulaic, and means is on the other side of the root, with the possible added connotation that it was previously on this side of the root.
We are now through the mountain.
He is across the street.
She is on the other side of the wall.
We will be through the forest [[soon]].
(Lit: We‘forestthroughwillbe smalltimewhen)
