The reference-tracking system of Tlapanec: Between obviation and switch-reference

This paper presents data on the Azoyú Tlapanec reference tracking system. The system is analyzed according to a procedure where default rules for how the system works are formulated and deviations are interpreted as being licensed by different levels of grammar organization along the lines of the local-global parameter proposed by Comrie (1989). The system is compared to its closest common typological congeners, obviation and switch-reference. Although it bears more resemblances to obviation, the system is neither clearly one of switch-reference, nor, indeed, of obviation.
