Hierarchy effects can be described as grammatical configurations in which the grammar must make reference to the ranking of a nominal argument– and often to the relative ranking of two nominal arguments––along some scale. This two-day mini course investigates hierarchy effects in several domains, including Person Case Constraint (PCC) effects, dative-nominative configurations, and copula constructions, along with recent theoretical proposals used to account for these. Day one will focus on hierarchy effects in the domain of pronominal clitics, and day 2 will focus on hierarchy effects in the domain of morphological agreement.
