This paper is based on field research comparison of dialects from two settlements on the island of Brač, Postira and Škrip. All attention is focused on the importance and preservation of the Chakavian dialect because it is important that people continue to use and remember original Chakavian words. The historical development of the island of Brač has greatly influenced the development of the speech of its inhabitants. In this paper, small differences between these two dialects are shown, especially the rich lexical fund and the words people have been using in everyday life until these days. In the original expression, poetry was created as well as many folk stories preserved for generations. The dialect from settlement Postira has so far not been well explored, while Filip Galović researched the dialect of the settlement Škrip. He linguistically analyzed the collection of poems called Glos sa škrop from author Stjepan Pulišelić. In order to better illustrate the beauty of Postirian dialect, poems from local poets and narrated stories are used in thi paper. This linguistic treasure is presented every year at the Festival of Chakavian dialects of the island of Brač in Škrip.
