Secondary predication at the interfaces
This project examines the syntactic, semantic, and prosodic structure of secondary predicates, or nonverbal expressions which share an argument with (but which are distinct from) the finite matrix verb in a clause (Heidinger 2022). In finite metrical corpora, including the RgVeda and the Homeric poems, depictive and resultative secondary predicates consistently appear in prosodically isolated positions (Hale and Kissock 2021). In modern languages, prosodic evidence reflects the special treatment of secondary predicates: in Modern Irish, the initial mutation system fails to apply across secondary predicate boundaries (Caso and Ó Muirthile to appear); in Georgian, pitch accent and tonal patterns set secondary predicates apart from attributive adjectives (Caso and Cooper to appear); in Italian dialects, consonant gemination fails to apply across secondary predicate boundaries (Caso to appear); in Serbian, the presence of a depictive secondary predicate is accompanied by a distinct sentential accent pattern (Caso 2023). These properties are compatible with a prosodic analysis of secondary predicates that includes extraposition to a level high in the prosodic hierarchy of each language, which in turn reflects their syntactico-semantic complexity.
