英語の原文（Wiktionary）
The noun is inherited from Middle English coper, copper (“copper ore; copper metal; bronze”), from Old English coper, copor (“copper”), from Late Latin cuprum (“copper”), a contraction of Latin aes Cyprium (literally “Cyprian brass or copper”), ultimately from Ancient Greek Κῠ́προς (Kŭ́pros, “Cyprus”) (a major source of copper during the Near East’s Bronze Age), from the name of a Northwest Semitic goddess from the root כ־ב־ר/ك ب ر (k b r) (“related to being big, large; great; or old”). Doublet of kobo. The adjective is from an attributive use of the noun. The verb is also derived from the noun.
