Etymology: Organomercurial is a plain compound: "organo-", from the Greek "organon" (tool, instrument, organ of the body), combined with "mercurial". The second element carries the more interesting story. "Mercurial" comes from Mercury, the Roman messenger god, and the metal was named for him because it moves so quickly and freely, a bead of quicksilver seeming alive in the hand. The adjective's sense of "quick-changing" or "volatile" in temperament grew from the same image of restless movement. The "organo-" prefix matters here because it marks the compound as one in which mercury is bonded to carbon-based molecules, the kind of chemistry that makes such substances toxic. Chemists formed the word by joining the two elements, a deliberate technical coinage rather than an ancient or traditional term.
