This study examines the usage patterns and discourse functions of the ‘ani X' construction as a complex discourse marker in Korean spoken discourse. It identifies and categorizes instances in which the discourse marker ‘ani' appears in combination with other expressions. The analysis shows that 37.8% of discourse marker tokens beginning with ‘ani' are realized in complex forms, indicating that such combinations are not marginal. Focusing on the most frequent types—‘ani keunde', ‘ani geu', ‘ani mwo', ‘ani geureonikka', and ‘ani geunyang'—the study illustrates how these constructions are used in various interactional contexts, including topic shifts, justification, mitigation, and the management of interpersonal stance. The study provides a descriptive basis for understanding complex discourse markers in Korean and highlights the analytical value of moving beyond single-word forms.
