Archaic A1 p- in Dakotan.

[BARudes at aol.com]

With respect to ‘snow', Catawba dialects and Woccon show three different
forms that appear to reflect reduplication.  I don't have the data in front
of me at the moment, but I seem to remember that either Saraw has wa:?, while
the Esaw has wa:?wa (or the first could be Esaw and the second Saraw), and
Woccon has something like Wawawa.  The w-w form in Siouan may result from
syncope in something like Catawba wa:?wa, while the Dakota form may be
comparable with Catawba wa:?.
