Did You Know?
Rugose was borrowed into English in the late 17th century from the Latin adjective rugosus ("wrinkled"), which itself derives from "ruga" ("wrinkle"). One descendant of "ruga" that you'll probably recognize is "corrugate," which initially meant "to form or shape into wrinkles or folds." Another, which might be more familiar to scientists, is rugulose, meaning "finely wrinkled." In addition, there is the noun "rugosity," which can refer to either the quality or state of being full of wrinkles or an individual wrinkled place.
