>Teton blo, Santee mdo, Omaha-Ponca nu, Osage to, Ioway-Otoe to,
Winnebago too.  Proto-Mississippi Valley is something like *pro, presumably
from *w(a)-ro, and the *pr cluster becomes *R in Dhegiha, Ioway-otoe, and
Winnebago.

Sorry, senion moment.  John's right about the reconstructed root (pun
intended).  *ro, not *to.  The rest of my post is OK. I think the *pr
cluster is really *wr.  Dakotan [b] is from */w/, not *p.
