Etymology: "Rugosus" is a Latin adjective meaning "wrinkled" or "full of wrinkles," formed from "ruga," a wrinkle or fold. The noun "ruga" is the older base, and it is the source of the English family of words built on it. "Rugosus" itself is the form that scientists and writers reached for when they needed a precise term for surfaces that are folded or puckered. English took the Latin adjective in its learned form, and it appears in technical descriptions of plant leaves, animal skins and anatomy, where a surface is described as rugose when it bears a network of creases or ridges. The word belongs to the same family as "rugged," which comes from a different route, through Old Norse and Middle English, and shares only an ancestral connection with the Latin root.
