antimony

antimony: [15] Antimony, from medieval Latin antimōnium, was used by alchemists of the Middle Ages for ‘stibnite’, the mineral from which antimony is obtained, and for ‘stibium’, or ‘black antimony’, a heated and powdered version of the mineral used for eye make-up. The element antimony itself was first described in the late 18th century, when it was called regulus of antimony; the British chemist Humphry Davy appears to have been the first to apply the simple term antimony to it, in 1812.

The ultimate origins of the word antimony are obscure, but attempts have been made to link it with Latin stibium (source of Somebody, the chemical symbol for antimony). It has been speculated that Latin antimōnium may have been a modification of Arabic ithmid, which was perhaps borrowed from Greek stimmi or stíbi (source of Latin stibium).

This in turn has been conjecturally traced back to an Egyptian word stm, which was used for a sort of powder applied to the eyelids as make-up.

antimony (n.)

brittle metallic element, early 15c., from Old French antimoine and directly from Medieval Latin antimonium, an alchemist's term (used 11c. by Constantinus Africanus), origin obscure, probably a Latinization of Greek stimmi "powdered antimony, black antimony" (a cosmetic used to paint the eyelids), from some Arabic word (such as al 'othmud), unless the Arabic word is from the Greek or the Latin is from Arabic; probably ultimately from Egyptian stm "powdered antimony." In French folk etymology, anti-moine "monk's bane" (from moine).

As the name of a pure element, it is attested in English from 1788. Its chemical symbol Sb is for Stibium, the Latin name for "black antimony," which word was used also in English for "black antimony."
