Etymology: The word comes from ancient Greek "rhagas," meaning "crack" or "fissure," the same root that gave Greek physicians a term for the small, split wounds that open in dry or chapped skin. English adopted the medical term as "rhagade," keeping the Greek sense of a fissure rather than the broader idea of any crack or break. The Greek noun belongs to a family of words built on the idea of breaking or bursting open, so the term describes the splitting itself rather than the pain it causes.
