General comment

Here the root htą́ke of sister (2) mSiEl’ is extended to younger sisters, and the derived form is typically used by a female Ego. The nature of the derivation is best shown in Biloxi, which has a transparent compound: tąk-aka = ‘sister (2) mSiEl’ + ‘younger’. The second root áka is encountered in several other kinterms, where it always designates younger members of a category.

This scenario requires postulating haplology in MVS: -kaka > -ka.

Crow iso•ká ‘her younger sister’ (GG-94, DEC-23) Hidatsa itá•ku ‘her younger sister’ (J) do not fit phonologically with forms found elsewhere in the family. The pre-Crow form was *to•ka, pre-Hidatsa perhaps *tu•ka with rightward vowel exchange and length fixed as a syllable feature. Vowel exchange typically affects u, not o. In addition, only short o’s raise to u in Hidatsa. Thus it is difficult to be certain of the Proto-Crow-Hidatsa form.
