This article tracks the origins o f the titles o f nearly thirty genres of literature and discusses them on the basis of tracking the origins. Tracking the origins of Sino-Vietnamese elements is made by the comparative - historical method in the linguistic research. The groups of titles are classified according to the correlation between the tracked-origin elements and the aspects such as the authors, the texts, the contents, the forms of the works. These correlations contribute to reflect the ancient people’s conceptions of literature, which has significance in studying the process of developing the Vietnamese medieval literature.
