ABSTRACT
North American languages exhibit a variety of agreement systems, including nominative-accusative, ergative-absolutive, hierarchical/direct-inverse, and agent-patient patterns, as well as phenomena such as object agreement, inverse number, and omnivorous number. This chapter examines the patterning and exponence of agreement in these languages, including the φ-features tracked by agreement, types of agreement systems and how these systems reflect grammatical alignment, debates about the syntactic status of agreement markers (as genuine agreement or clitics), and the points at which agreement can occur in the clausal spine.
