As already said, Hopi. Hopi is polysynthetic, with up to AFAIR 5 prefixes
and up to 5 suffixes that you can attach to the root. Agian AFAIR the first
suffix in a clause shows relative time/aspect/something like that with
respect to the previous clause, such as immediate following, preceding,
cause, result and others, including, again AFAIR, gnomic. The grammar
was available online on Rosetta Project about a decade ago, and I've been
trying to TeXify then, but now I'm unable to find the files. But I'm really
thinking some you will definitely find it after some googling today.
