Thank you, everybody who replied to this question!  Several people
expressed interest in reading the essay; now that I've handed it in, it

The main conclusions were that:<br>
<br>
* <span style="font-size: 12pt; line-height: 150%; font-family: "Times New Roman";" lang="EN-US">Proto-Siouan-Catawban (and Proto-Siouan-Yuchi, but not Proto-Macro-Siouan) productively formed
pluractionals from verb stems by full stem reduplication.<span style="">  </span>Every branch of the family exhibits reflexes
of this process, although these have often been affected by semantic extensions
and morphological contractions.<span style=""> <br>
* Stoney "adversative" reduplication is most probably borrowed from a Salish language.<br>
