<![CDATA[This study investigates code-switching patterns across different Sasak dialect zones in Lombok Island, employing a corpus-based sociolinguistic approach. The Sasak language, spoken by approximately 3.5 million people in Lombok, exhibits significant dialectal variation distributed across five recognized dialect zones: Ngeno-Ngene, Meno-Mene, Ngeto-Ngete, Kuto-Kute, and Meriak-Meriku. Despite increasing scholarly attention to Sasak dialectology, the phenomenon of code-switching between Sasak dialects and Indonesian—particularly across different dialect zones—remains underexplored. This research addresses two main questions: (1) what are the dominant code-switching patterns in each Sasak dialect zone, and (2) what sociolinguistic factors influence the variation in code-switching behavior across these zones. Data were collected from a geographically-tagged digital corpus comprising 12,480 utterances gathered from 156 speakers across 26 observation points in Lombok. The analysis employed Poplack's (1980) typology of code-switching (tag-switching, inter-sentential, and intra-sentential) combined with Myers-Scotton's (1993) Markedness Model. The findings reveal that inter-sentential switching is the most prevalent type across all dialect zones (48.3%), followed by intra-sentential (34.7%) and tag-switching (17.0%). Significant variation was found across dialect zones, with urban-adjacent zones (Ngeno-Ngene) exhibiting higher rates of intra-sentential switching, while peripheral zones (Meriak-Meriku) showed greater preference for tag-switching. The results suggest that geographical proximity to urban centers, speaker age, and education level are the primary sociolinguistic factors driving code-switching variation across Sasak dialect zones.]]>
