The Interaction of Agreement and Case
Important to the proposed analysis of Choctaw verb agreement is the disjunctive application of the conditions for agreement. We saw in the last chapter that this disjunctive application arises in Choctaw for the same reason that verb agreement rules in Southern Tiwa and Tigre are disjunctively applied: a single form satisfies more than one rule, but only one rule can apply to that form. In this final chapter, I examine Choctaw case more closely, showing that the conditions for nominative and oblique case assignment stand in a disjunctive relationship. Further, by examining the interaction of case and agreement, we find that the two most salient morphological marking systems interact to provide a transparent view of Choctaw clause structure; the result is an account superior to one that takes agreement and case as lexical properties as has been proposed elsewhere in the Choctaw literature and to a specific account proposed by Heath (1977).
