The Importance of Post Positions in Conlanging

Amunyar predated the ergative trend in conlanging and he might even have kicked it off. The suffixes go on the post position itself, which is another bizarre thing you don't see with other languages. There's not really enough examples to get a sense of what these are or even a list of all the post positions. It looks like you'd have to have a lot of post positions to justify having classes up to my thank you.
