Etymology: Estratriene is a technical coinage from chemistry, built by stacking three parts that each name a piece of a molecule. The "estra-" element is itself a shortened form of "oestrogen" combined with the steroid-naming pattern, and it marks a steroid skeleton with a particular arrangement of carbon atoms. The "tri-" part counts three double bonds, and the "-ene" suffix is the standard chemical ending for an unsaturated hydrocarbon, the same ending found in "benzene" and "ethylene." Put together, the name describes a specific steroid framework carrying three carbon-carbon double bonds. Chemists assembled this kind of systematic name so that anyone reading it could reconstruct the molecule's structure from the label alone, rather than relying on a memorised trivial name. The word therefore has no older everyday sense to trace; its meaning was fixed at the moment the naming convention was applied to this class of compounds.
