Etymology: Tetrachloride is a plain technical compound name, built from two parts that each carry a clear history. The first part, "tetra-", comes from Ancient Greek "tetra-", the combining form of "téssares", meaning "four". The second part, "chloride", is a modern chemical coinage: "chlor(ine)" comes from Ancient Greek "khlorós", meaning "pale green" or "greenish yellow", a reference to the colour of the gas, and the "-ide" ending is a suffix used for binary chemical compounds, derived from "oxide" and related formations. Put together, "tetrachloride" simply means a compound with four chlorine atoms per molecule, a sense the name spells out directly. Chemists use the same "tetra-" prefix in other names, such as "tetrahydrate" or "tetroxide", so the term follows the systematic naming conventions that developed in nineteenth-century chemistry.

Synonyms: carbon tetrachloride, tetrachloroethylene, chlorinated hydrocarbons, halogenated compounds, organic halides
