Complementation in linear and dialogic syntax: The case of Hebrew divergently aligned discourse

This study investigates the interaction between linear and dialogic syntax in Hebrew conversation. Analyzing resonance in divergently aligned contexts, we examine a particular dialogic modification of complex syntactic constructions: the embedding of one construction within the scope of another. Specifically, we examine a family of constructions which, in the terms of linear syntax, are analyzed as forms of complementation (via the complementizer še- 'that', via a question word, or via the conditional conjunction 'im 'if'). However, the dialogic alignment of these forms with their preceding utterances reflects a complex picture, in which some patterns are still definable by linear syntax, but others are not accounted for by these traditional terms. Rather, the application of the Dialogic Syntax framework calls into question defining such constructions from a purely structural perspective and supports a more fluid, Emergent Grammar approach. Moreover, we illustrate how dialogic actions in fact motivate the interaction-based grammaticization of new constructions, culminating, in the case of the constructions examined here, in the emergence of discourse markers.
