This work examines the image-forming verbs of the Yakut and Tyvan languages, selected from the Yakut olonkho Dyyray Bogatyr, The Son of the Horse by I.I. Burnashev and the Tyvan heroic epic Khunan Khara by Chanchy-Hoo Oorzhak in order to identify semantic equivalents and functional features of verbs in epic texts, which will contribute to the definition of genetic communities and differences between the Turkic languages and the epic tradition. In analyzing of material, the method of continuous sampling, component analysis method, method of context (distributive) analysis and comparative method were used. The Yakut storyteller pays more attention to detailed and figurative descriptions to create entertainment, colorful pictures and actions, and the Tyvan storyteller – to movements, the course of actions for liveliness and brightness of the course of events, the development of plots. Yakut verbs are used in their original forms and in the forms formed using affixes of specific forms. And Tuvan verbs are used in forms based on the affixes of word formation of verbs and auxiliary verbs. The result of the study allows us to conclude that the functional feature and commonality of the Yakut and Tyvan image-forming verbs lie in their direct participation in the creation of images, description of pictures, and characterization of actions and transmission of feelings.
