Units in interaction are emergent real-time phenomena that can be accomplished by the coordinated deployment of language and the body. Focusing mostly on data from dance classes, this study looks at how incomplete syntax projects a continuation realized by the body, and systematically accounts for clausal syntax that can incorporate an embodied demonstration. It is argued that the classic list of types of turn-constructional units by Sacks et al. (1974) needs to be expanded with a syntactic-bodily one, and that the syntax of embodied demonstrations has to be included in the grammatical description of language.
