Etymology: Xeroderma is built from two Greek roots. "Xēros" meant "dry," and "derma" meant "skin," so the word literally names dry skin. The first element, xero-, appears in other scientific coinages such as "xerophyte," a plant adapted to dry conditions, and "xerography," a dry photocopying process, which share the same Greek source. The second element, -derma, is the same Greek noun that gives English "epidermis," the outer layer of skin, and "dermatology," the study of skin. Physicians working in the nineteenth and twentieth centuries assembled such compounds from classical roots to name conditions precisely, so the word is a technical coinage rather than an ancient term. Ancient Greek writers had no word for this specific condition.
