The reasons for the emergence of ecolinguistics are, among others, a result of the progress of human ecology because of the interconnections and interdependencies between all types of systems (including economic systems, social systems, religious systems, cultural systems, linguistic systems, and ecosystems) which are continuously highlighted and explored. The research aims to describe ecolexicon social praxis dimensions in mosehe wonua's ritual. This study was designed with a qualitative approach. This approach was chosen because it can answer the problem formulation that has been formulated in the previous introduction. A qualitative approach is used to answer the problem formulation. The data of this research are written data taken from the published manuscripts of Tolaki oral literature. The result shows that the social praxis dimension of the Mosehe Wonua ritual mantra lexicon affects UDB in Poasia District. The biological dimension is demonstrated through the persistence of the proper reference of each lexicon. The ideological dimension refers to the lexicon used in the metaphor for the symbol of reference to the concept referred to in a situation. Finally, the sociological dimension is shown through the use of ritual lexicon in conveying a particular concept by speakers and listeners of UDB in the Poasia District. In this case, the mosehe wonua ritual needs to be preserved because it contains an eco-collection that represents the Tolaki-speaking Guyub culture so that the younger generation can know the philosophical meanings contained therein and provide an economic impact by realizing Kendari City as a tourist city.
