This study investigates whether other relationships in sentence structure besides the "brother-in-law" relation sanction surrogate agreement in Zinacanteco Tzotzil (Mayan). Surrogate agreement refers to cases in which an element that lies outside the class of regular agreement controllers in a language (the surrogate) controls subject-verb agreement instead of the nominal whose final grammatical relation would normally entitle it to control agreement. In Zinacanteco Tzotzil, agreement is regularly controlled only by final subjects and by final direct objects. However, in three constructions, agreement is controlled by an element that is neither a direct object nor a subject. In these cases, the controller of the agreement can be characterized as a nominal that hosts the ascension of a nominal that is a final direct object or final subject. Therefore, while the controller itself is not a regular agreement controller, it is always connected to a regular agreement controller. Tzotzil agreement rules are explained in detail, and the different forms of surrogate agreement (possessor ascension and conjunct union) are discussed as they relate to Tzotzil agreement. It is concluded that both the host relation and the brother-in-law relation can sanction surrogate agreement. (DJD)
