If there is a bound vs. free split, the bound prefixes will be accusative, and case marking on free forms will be ergative.
Standardized
Whenever there is an alignment split between bound and free pronouns, bound (i.e. agreement) forms are more likely to align accusatively, while case marking on free forms is more likely to align ergatively.
1. Dixon gives two examples for this distribution: Murinypata (Daly, Australian) and Gahuku (Trans-New Guinea). 2. A. Harris 1997: 372 mentions one more example of this type: Udi (Lezgian, E. Caucasian) has case marking with ergative alignment and verb agreement with accusative alignment. She adds: “… it is not very likely that Dixon could have been aware of [this example] in forming his generalization”.
