Sinj region is constituted in the Middle Ages, one of the central parts of Croatian counties Cetina. Covering the area around the top and the middle of the river canyon, this is a county on the north side was surrounded by great natural wall Dinara mountain range, and to the west Svilaja chain. Precisely because of its position to say that the town of Sinj is extremely important in our history. The subject of my study has just been Sinj region, partly because I was born there, and partly because of its large and rich cultural heritage. Cetina river gave the name and life of this area. It constitutes the core of the people and their lives. In writing this article, I realized just how wealth and Frontier. All of these seemingly ordinary people to protect themselves something treasured, and it is an oral literature that is passed from generation to generation. I interviewed different people, different age groups, and it was extraordinary to be a part of history that I have successfully recorded. My informants were born in this area, living here and the end of their home. Their language is specific to the area and is mainly based on the elements of Neo-Štokavian Western tian dialect, so the work contains phonological and morphological analysis of each word as well as further explanation of the lexicon. Historical periods have greatly influenced the lives of these people and so on literature that has evolved here. Specifically attacks Turks and stories about heroic people of this region is known throughout the world. We must emphasize the importance of oral tradition because it is one of the ways in which the spirit lives in this area, and keeps the tradition and culture of a people.
