TETON

[Alan H. Hartley]

Just came across the following in J. E. Colhoun _Exped. St. Peter's
River_ (1824, p.424):

"We were told that the Iawas were formerly a band of the Dacotas, and
that they were distinguished by the term of Titatons, but that they
separated long since, and that their language had been so much altered
as to be unintelligible to the Dacotas."

This looks like thiNta 'prairie' + -thuN(-waN) 'village', which would
support the 'prairie-village' etymology of TETON (if this supposed name
for the Iowas is in fact identical with TETON).
