This research delves into the intricacies of adversative coordination in Korean Sign Language (KSL), focusing on its manifestations across three semantic categories: 'semantic opposition,' 'denial of expectation,' and 'correction.' Through comprehensive analysis of both manual and non-manual elements, this study explores how these linguistic phenomena are intricately intertwined with the formation of sign languages. Drawing on the concept of grammaticalization, which transcends linguistic boundaries, we investigate how adversative coordination in KSL exhibits universal traits observed in spoken languages worldwide. By examining the structural and functional aspects of adversative coordination in KSL, this research contributes to a deeper understanding of the linguistic mechanisms at play in sign languages and illuminates the universality of language evolution and structure.
