This study aims to analyze the construction of serial verbs in Sundanese using the X-bar theory. Data sourced from written Sundanese as the main data and spoken data as supporting data. The method used in this study is a descriptive qualitative method using the X-Bar theory introduced by Noam Chomsky. The results of the analysis show that the Sundanese serial verb construction (BS) has three constructions namely coordinate KVS, incoative KVS, and configurational KVS. Based on the structure of its construction, Sundanese as a language that is typologically classified as an SVO language. The construction of serial verbs in the BS has typological characteristics of a verb-framed language. In terms of syntactic structure, Sundanese serial verbs can have the X-KOMP or X-ADJ structure. These findings contribute to our understanding of serial verb constructions in Sundanese by delineating specific syntactic patterns and typological characteristics unique to the language. The implications of these findings extend to broader language studies, offering insights into the syntactic behaviors of SVO languages and providing practical applications for language preservation and educational frameworks.
