Etymology
Origin of nevus
1685–95; spelling variant of Latin naevus mole
Explanation
A nevus is a mark on the skin, like a mole or a birthmark. Many people are born with a nevus somewhere on their bodies. Can you find yours? Whether you have a strawberry birthmark on your cheek, or a series of tiny moles dotting your shoulders, you can say you have a nevus. This word is most often used by doctors, including dermatologists (skin doctors), who like to keep an eye on nevi (which is the plural form of nevus). Every once in a while, a nevus will develop a malignancy, or become cancerous. The Latin root of nevus is gnaevus, "born in," or "birthmark."
