Etymology: Earthenworks is a plain compound: "earthen," meaning made of earth or clay, which comes from Old English "eorthen," an adjective formed from "eorthe" (earth) plus the suffix "-en," meaning made of, and "works," meaning fortifications or constructions. Put together, the word is a straightforward description of something built out of soil. The "works" part is the more interesting half. In military and engineering use, "works" has long meant fortifications, so an earthwork is a defensive bank, rampart or ditch thrown up from dug-out soil. Archaeologists later applied the term to prehistoric monuments such as the great mounds and enclosures of North America and Britain, which is why the word now often sounds ancient even though its parts are ordinary.
