Title:  Unifying anti-agreement and wh-agreement


In this talk, I investigate the sensitivity of φ-agreement to features typically associated with Ā- extraction, including those related to wh-questioning, relativization, focus and topicalization. This phenomenon has been referred to as anti-agreement (Ouhalla 1993) or wh-agreement (Chung and Georgopoulos 1988; Georgopoulos 1991; Chung 1994) in the literature. While anti-agreement is commonly held to result from constraints on the Ā-movement of agreeing DPs, I argue that it reduces to an instance of wh-agreement, or the appearance of particular morphological forms in the presence of Ā-features. I develop a unified account of these Ā-sensitive φ-agreement effects in which they arise from the ability of φ-probes to copy both φ-features and Ā-features in the syntax. In the morphological component, partial or total impoverishment may apply to feature bundles containing both φ- and Ā-features, deleting some or all of the φ-features. Impoverishment blocks insertion of an otherwise appropriate, more highly specified agreement exponent. I present case studies of the effect of Ā-features on φ-agreement in three languages: the West Caucasian language Abaza (O’Herin 2002); the Berber language Tarifit (Ouhalla 1993; El Hankari 2010); and the Northern Italian dialect Fiorentino (Brandi and Cordin 1989; Suñer 1992). I show that in all three languages, the agreement exponents that appear in the context of Ā-features are systematically underspecified.
