I recently started looking into this old conlang of mine:
http://www.frathwiki.com/Proto-Kunnu-l%C5%ABjungo
I based it on Finnish so I could quickly create a protolang without having to think too much about grammar. I remembered it being a total relex of Finnish and the article being more or less a stub, but it turned out that it wasn't that bad. It has several things Finnish doesn't have, and I had written quite a lot about it.
But I can't quite make sense of all of this, so I wanted to ask if anyone here can.
There are two things in particular that I can't understand now, years later.
One thing is that this is supposed to be a split ergative language. It has an ergative case and a nominative-absolutive case. What on Earth is a nominative-absolutive case? I must've gotten it from Wikipedia somewhere, but I can't find that anymore. I remember being told once on ZBB that in a normal ergative language the argument of an intransitive verb will typically be a patient, experiencer, undergoer or somesuch. Is this correct? And if the argument instead is usually an agent, then that would make it a split ergative language?
The other thing I don't understand is that this language has an active voice, a passive voice and an "unmarked voice". >_<
Simply put, the unmarked voice is used in transitive sentences and the active voice in intransitive[...]
In intransitive sentences, any voice except for the unmarked voice can be used.
So the active voice is the default voice used on intransitive verbs, and the unmarked is the default voice used on transitive verbs? What could the purpose of this be? It seems like the active voice just marks a verb as being intransitive. So the unmarked voice is not used on intransitives, but can the active voice be used on transitives? There doesn't seem to be any example sentences where that occurs. I don't know if that's because it is indeed disallowed, or because I just hadn't thought of making such examples.
Is anyone able to analyze this conlang better than me? If the way the voices work right now is dumb, is it possible to take this active-unmarked distinction and make something sensible out of it?
