    From the medieval latin 'antimonium', originally applied to stibnite. The etymology is uncertain; the popular etymology, from ἀντίμοναχός anti-monachos or French antimoine, still has adherents; this would mean "monk-killer", and is explained by many early alchemists being monks, and antimony being poisonous.
