Antipassive” from the Oxford Handbook of Ergativity

Syntactic Ergativity” from The Blackwell Companion to Syntax

Deconstructing Ergativity: Two Types of Ergative Language” from Oxford University Press

Ergativity and the Complexity of Extracton: A View from Mayan” from Natural Language and Linguistic Theory

Tsez Syntax” personal manuscript
