[LAB] Evans et al. (2018a,b) introduce the notion of ‘engagement’ as a new grammatical domain related to intersubjective coordination of knowledge. The present paper applies this notion to data from the Australian Aboriginal language Ungarinyin. It identifies three markers/construction types in the language as expressions of engagement and develops a descriptive framework rooted in Bakhtinian Dialogism in order to demonstrate why these expressions represent the category. It is argued that the main problems that arise in the analysis of engagement are very similar to those that have been encountered in the description of (other) TAME-categories as well, and that these may be overcome by applying Mikhail Bakhtin’s idea of ‘addressivity’. It concludes that a better understanding of the category of engagement that explores its relation to addressivity may contribute to the development of an approach to grammar in which sociality takes priority, a Dialogic linguistics.
