Etymology: Organochlorides are a plain technical coinage, and the history is simply a combination of two existing parts. The first part, "organo-", comes from "organic," a word that traces back to the Greek "organon," meaning "tool" or "instrument." The second part, "chloride," is built on "chlorine," a name derived from the Ancient Greek "khlōrós," meaning "pale green" or "greenish yellow," a reference to the gas's colour. "Chloride" was formed by adding the suffix "-ide," used in chemistry to name binary compounds, to that element name. Put together, "organochloride" simply means a compound that contains both carbon-based organic structure and chlorine. The plural form, "organochlorides," refers to the whole class of such compounds, so the word is a direct label rather than a story of shifting meaning.
