yam means: The sweet root vegetable is similar to sweet potatoes, with pointed ends, yellow-orange colors, and subdued yellow-orange coloring. A darker variety, called cush-cush, grows in Mexico and the Southern United States. It produces smaller and more delicious yams. Although there are many varieties, the true yam is different from a sweet potato. When cooked it is bland and very dry. (in Cooking Dictionary)
