Integrating deictic co-speech gestures in demonstrative forms
Deictic co-speech gestures (DCSGs) are commonly regarded as intimately related to exophoric demonstrative forms;
yet, no account is available that formalises this relation. This paper proposes that DCSGs spell-out part of the internal
structure of exophoric demonstratives: concretely, they contribute the spatial coordinates (direction and distance, syntactically
encoded by the Demonstrative ‘Dem’ head and by a Measure Phrase ‘MeasP’ that modifies it, respectively) that identify the location
of the demonstrative’s referent and the deictic centre. This naturally captures the intuition that exophoric demonstratives and
DCSGs are related, under a multi-modal spell-out approach to demonstrative forms. Further, this proposal is compatible with
independent facts regarding both the grammaticalisation of demonstrative forms and their acquisition.
