The Different Types of Morphosyntactic Alignment

Some languages have one set of endings and others have a different set of endings to accommodate the intentional versus non intentional classes. The subject of an intransitive verb and the subject of a transitive verb all get different marking which is extremely rare but her tripartite for string of lesson is different in that it's sort of like nominative and accusative with this extra weird thing. And what's interesting though to me is that it makes you expect these sort of some in some languages ergativity whether you use a split or if you're in a split ergative system.
