Etymology

Origin of watermelon

First recorded in 1605–15; water + melon


Explanation

A watermelon is a plant that grows vines and flowers that ripen into large, juicy fruit also called watermelon. Cold watermelon is delicious at a backyard barbecue. Like squashes and gourds, watermelons grow from long, climbing vines. The deep pink or red flesh of a watermelon, however, is uniquely sweet, juicy, and refreshing. Watermelons are originally native to Africa, and they were brought to North America and cultivated around the 16th century. For many people, it's just not summer without watermelon — the fruit is over 90 percent water, so it's not just delicious, but it also quenches your thirst.
