Etymology: Scurf is one of those English words that has stayed close to its physical origins. Its Old English ancestor, "scurf," meant a scab or scaly skin disease, and the word's deeper roots point to an action rather than a condition: the Proto-Germanic form is linked to a verb meaning "to gnaw," and the Proto-Indo-European base beneath it means "to cut off, sever." Something that is scraped or gnawed away from the skin, in other words, gave the word its name. The same root survives across the Germanic languages. Dutch has "schurft," German "Schorf," and Danish "skurv," all meaning scab or crust, which shows how widely the idea of a crusty, peeling skin condition was shared among the speakers of these languages. Over time, the word's meaning narrowed from a diseased skin to the loose flakes that drop from healthy skin, the dandruff that falls from the scalp. Modern dictionaries still record that everyday sense, so the word now describes the flaking itself rather than the illness that once gave it its name.
