Managing turns, building common ground, planning discourse. Discursive and interpersonal functions of Italian no(?)

This paper discusses the discursive and interpersonal functions conveyed by the Italian negative operator no(?) ‘no’, suggesting a possible pathway of functional enrichment that can account for its high degree of polyfunctionality. Drawing on the KIParla corpus of contemporary spoken Italian, we chart the values of no(?) as a discourse marker, which are all clearly connected to the incremental co-construction of discourse in interaction, either in terms of turn management or of shared knowledge and mutual alignment. We then explore its sociolinguistic distribution, showing that register variation plays a major role in this respect. We argue that conversational uses of no(?) as a discourse marker, including its role as a pause-filler, are motivated by cooperative needs in discourse construction, shaping its functional profile at the intersection of mental processes and communicative practices.
