Pumpkin is a type of squash that belongs to the Cucurbitaceae family. It has a distinctive round shape and orange or yellow skin, with seeds and pulp inside. Pumpkins are typically used for cooking, baking, and carving into jack-o'-lanterns during Halloween celebrations. They can also be used to make pies, soups, stews, and other dishes. The word "pumpkin" is often used interchangeably with the term "squash," although there are some differences between the two in terms of taste, texture, and culinary uses.
