Based on original fieldwork data, we discuss the array of uses of yimarne ‘like’ in Kunbarlang (Gunwinyguan, non-Pama-Nyungan; northern Australia), focusing on its reported discourse (RD) functions. First, we describe the range of functions that attest to yimarne’s grammaticalization, and propose a mechanism of domain extension that may underlie the development of the different uses. Then we present an analysis of the distribution and syntax underlying the quotative use of yimarne to contribute to the existing literature on the syntactic typology of quotative indices (QIs), as well as to the description of grammaticalization pathways for similative markers.
