Etymology: Arsenicum is the Latin name for the element we call arsenic, and the Latin word was itself borrowed from Greek. The Greek "arsenikon" was a word for yellow orpiment, the golden-yellow mineral arsenic sulfide, and it was later applied to the element and to white arsenic, the poisonous oxide. The Greek word may have been linked to "arsen", meaning "male" or "strong", a sense that reflects how potent the substance was thought to be, though the connection is uncertain. The Latin form entered English through medieval scholarly writing, where alchemists and physicians used it as a learned term. English speakers adopted the modern spelling "arsenic" from French "arsenic", which kept the Greek-derived name in a form close to its Latin ancestor.
