купорос
Russian edit
Etymology edit
Inherited from Middle Russian купоросъ (kuporos) (att. since 1582), from a Western European source like Middle French соuреrоsе (Russia didn't trade directly with France in the 16th century, making some intermediary likely), from Old French coperose (whence English copperas), from Latin cuprum (“copper”) and rosa (“rose”), likely calquing Ancient Greek χάλκανθον (khálkanthon, “solution of copper sulfate”).
Pronunciation edit
