Etymology: "Organomercurials" is the plural of "organomercurial", a noun for a chemical compound in which mercury is bonded directly to carbon. The word is a compound of two parts: "organo-", the combining form that signals carbon-based chemistry, and "mercurial", which here carries its chemical sense of containing mercury. Its formation is plain and technical, a modern coinage built from familiar parts rather than a word that drifted through centuries of use. The second element is the more interesting one. "Mercurial" comes from Mercury, the Roman messenger god, and originally described people or things under the planet's influence, which the old theory of humours linked to quick, changeable temperaments. The name of that swift god passed into the language of alchemy and then chemistry, where the liquid metal that moves so quickly and freely was named after him. Adding "mercurial" to "organo-" therefore yields a term meaning, roughly, "carbon compound of quicksilver."
