Abstract
This article investigates the Minangkabau language, with a particular focus on dead words identified in Koto Gadang Guguk-Solok, West Sumatra. The primary objective is to uncover words that are no longer actively used by the local community. Employing a descriptive qualitative method, the researchers analyzed the data through detailed explanations. Data collection involved collaboration with informants who provided insight into words that have fallen out of usage in the region. The gathered information was then classified according to the types of language change and the factors contributing to the disappearance of these words. The findings revealed that, of 197 words suspected to be obsolete, 89 were confirmed as dead words. The results highlight lexical change as the most prevalent form of language change, with language contact identified as the main driving factor behind the loss of these words.
