To the ethnologist and to the philologist the Dakotas and those speaking
kindred languages are a very interesting people. There are four
principal Dakota dialects, the Santee, Yankton, Assinniboin and Titon.
The allied languages may be divided into three groups:
I. a, Winnebago; b, Osage, Kaw, and 2 Quapaw; c, Iowa, Otoe and
Missouri; d, Omaha and Ponka.
