Information about the material and spiritual culture of the Yakuts is encoded in the names of wild edible plants. This article analyzes 42 phytonyms. Their morphological structure is discussed and attention is paid to their lexical-semantic features. Names can reflect some external similarity with objects or other plants, the place of growth, some peculiarities of the morphological structure, the plant’s color, the characteristics of its growth, ist nutritional properties, its surface, or its practical use. Copies from Russian are frequent, owing to the long-lasting cohabitation of Yakuts and Russians. Some non-derivative stems go back to Mongolian and Tungusic forms, which testifies to close linguistic contacts with these languages.
