A cucumber is a long, thin vegetable with green skin and juicy insides. It's often eaten raw in salads or sandwiches.
Cucumbers are super popular in summer because they're cool and refreshing. You might find them sliced up in a watermelon salad or as a crunchy addition to a sandwich at a picnic. Some people even use cucumber slices as a garnish for cocktails, like a fancy martini. If you've ever had a spa treatment that includes a cold compress on your eyes, it was probably made with chilled cucumber slices. People love cucumbers because they're easy to digest and add a lot of flavor to dishes without being too strong.
A vine in the gourd family, Cucumis sativus.
