The understanding of a folk narrative lies in the underlying principles that govern its composition. This study focuses on structures and culture found in the folk narratives of Sama, an indigenous group in Island Garden City of Samal, Philippines. The paper uses the theory on narratology by French-Lithuanian literary theorist, Algirdas Julien Greimas, and cultural theory by Bronislaw Malinowski to analyze the selected Sama folk narratives. The study reveals that the ten (10) Sama folk narratives collected do not completely follow the theory on narratology of Greimas. This is because the theories used are foreign and the folk literature collected are of local origin. Regardless of this, the study shows that Sama folk narratives reflected the ways of their people. Consequently, Sama folk narratives exemplify their cultural practices. They present social, economic, political, and religious practices. The leaders from the Sama folk were requested to validate the cultural texts gathered for this study. This research highlights the structure of Sama literature and illustrates Sama’s cultural heritage by gathering and analyzing their folk narratives so that the rest of the population (the new generation) could have the chance to experience their culture and appreciate it. Also, the researcher further emphasizes the relevance of gathering and using local literature to prevent it from vanishing into oblivion.
