General comment
Lakota čh, DH *r betray the presence earlier of an inalienable
possessive prefix, *i-, on this body part term. Osage alone among the
daughter languages has kept (or restored?) the prefix. There has been a (not
uncommon) accent shift rightward in Lakota after loss of the old prefix. The
identity of the final vowel is unclear here. Lakota stress placement indicates
that the final vowel is not the ablauting vowel, an interpretation supported
by the final vowel in Quapaw, but since -E is a feature of verbs in Siouan,
spreading to nouns only analogically, this noun could have had *-e. The
Quapaw form also shows an unexpected reflex of *R instead of *r.
