A watermelon is a large, round fruit with a thick green rind, often featuring stripes or patches. Inside, its flesh is typically juicy, sweet, and pink or red in color, dotted with black seeds, although seedless varieties also exist. Watermelon is grown in favorable climates from tropical to temperate regions worldwide.

Examples:

1. My sister gave me a sweet watermelon for snack.
2. I am craving for a watermelon.
3. The gardener proudly showed off his giant watermelon, bigger than a beach ball!
