Lexical and syntactic compounding in Dakota

[R. Rankin]

The verb is /ska'ta/ and it is an "ablauting" verb (Kaw cognate /ska'je/).  That
makes it a "C# root" in Dakotan.  The -t > -l before the boundary.  Beyond that,
I can't account for its behavior.

> s^kal o' mani   (he goes about in order to play) (lexical compound)
