Is There a Prepositional Linking Verb?

I think this is a really nice language to look at because it's not overwhelming in its complexity, but still has a natural degree of irregularity here and there. The descriptions leave something to be desired because he just kind of associates them with case terms, but doesn't really explain how they're huge. There are what are they called direction prefixes on the verb. You know, I'm trying to find out one in their arc and there are five of them. It's an interesting language. We'll have a link to it.
