This research discusses the lexicon used for traditional technology systems in the Tolaki community. Lexicon is a language component containing all information about the meaning and usage of words; the richness of words a language has. Lexicon runs into a shift due to certain factors such as changes in norms, culture, and environment caused by the development of science and technology. This research aims to analyze the level of shift and change in the meaning of the lexicon for traditional technology systems in the Tolaki community in Konawe Regency, Southeast Sulawesi. The method is qualitative descriptive. The data are taken from written sources, literature studies, by examining and recording some lexicons from the book “Tolaki Culture” by Abdurrauf Tarimana related to the lexicon in the traditional technology system of the Tolaki community. The validation of the data is then substantiated by questionnaire distribution in which the informants fill in lexicon data about agricultural technology systems and imply them in Tolaki language. The theory used is the lexical-semantic theory proposed by Pateda. The results showed that the lexicon for the Tolaki agricultural technology system is extinct and there is a shift in the lexicon.
