In particular, limited research has examined DMRs with the structure more + adverb, owing to their infrequency (Silva et al. 2024). This study employs the cooptation hypothesis (Heine 2013) to provide a deeper understanding of how the adverbial more correctly has evolved into a DMR. The development of discourse markers (DMs) in general has notably challenged grammaticalization theory, leading scholars to explore a variety of frameworks that can account for their unique behaviour (see Norde 2009; Furkó 2014; Traugott 2018; Heine et al. 2021b). These frameworks include pragmaticalization, lexicalization, and, most recently, the cooptation hypothesis. By using four large-scale corpora, this study argues that the interplay between cooptation and grammaticalization—not merely grammaticalization on its own—has shaped the emergence of more correctly as a DMR.66endiscourse markers of reformulationgrammaticalizationcooptation hypothesisThesis
