Etymology

The word "copper" originates from the Old English "coper," borrowed from Late Latin "cuprum," which itself derives from Latin "aes Cyprium" (literally "metal of Cyprus"). Cyprus was a major source of copper in antiquity, and the name became synonymous with the metal. Over time, "cuprum" evolved into "coper" in Old English and later "copper" in Modern English.
