Meaning & usage
arsenic (chemical element, symbol As)
Where this word comes from
Shortening of arsenikk, arsenic trioxide, from Ancient Greek αρσενικόν (arsenikos), "arsenic, orpiment", though it literally translates to "manly, strong", due to it being a folk etymology of Middle Persian زرنيخ (zarnikh), "gold-colored". The word orpiment is the proper word in English for arsenic trioxide, though arsenic is still used in this sense. In Norwegian, arsenikk only refers to the mineral.
