Then it's not Arabic.
Anyway, is everyone still okay with the genitive case staying the prepositional case? In all honesty, I'm still for the 20+ case system.
But that's impractical.
I'm OK with the genitive case being the prepositional case.
But anyways, how would that 20+ cases system be? Which cases would it include? Most of them would be locational cases, right?
I think we could have a rich case system for precise indications, and maybe a set of prepositions for simpler assertions: We'd have a word meaning "by the" that could act as the adessive, inessive, allative, illative, etc. And another for motion away from, or being off of something...
This chart seems neat!
