Yams are a type of root vegetable. There are over 600 varieties of yams, each with its own unique flavor and texture. They come in a variety of shapes, colors, and sizes. It can be boiled, roasted, mashed, or fried.

Examples:

1. My mom roasted the yam until the skin became crispy, and the inside was soft and fluffy.
2. Japanese yam has a hairy, brown skin and it's slimy.
3. My grandma used to make the best crispy fried yam fries with a spicy dipping sauce.
