<![CDATA[This study examines Sundanese–Indonesian code-mixing in Sule’s podcast featuring Dedi Mulyadi by analyzing its forms, contributing factors, and social functions in digital discourse. Employing a descriptive qualitative approach grounded in sociolinguistic analysis, the study analyzes spoken utterances containing Sundanese–Indonesian code-mixing from a YouTube podcast video. Data were collected through observation and transcription of podcast utterances and analyzed by identifying and classifying code-mixing according to linguistic units and Muysken’s framework of insertion, alternation, and congruent lexicalization. Contributing factors and social functions were interpreted contextually based on speakers’ relationships, conversational topics, and communicative purposes. The findings show that Indonesian functions as the dominant language, while Sundanese occurs in words, phrases, and clauses. The identified forms are insertion and alternation, while congruent lexicalization was not found. Code-mixing occurs for emphasis, humor, emotional expression, indirect criticism, intimacy, and cultural identity. Its occurrence is influenced by relationships, conversational situations, topics, and communicative purposes. Sule’s role as a comedian and Dedi Mulyadi’s role as a politician also shape Sundanese use as a resource for humor, criticism, solidarity, and cultural identity. These findings demonstrate that code-mixing functions not only as a linguistic practice but also as a contextual social and communicative strategy in digital public discourse.]]>
