Etymology: Calciferol is a deliberate coinage from 1931, built by blending two words: "calciferous" and "sterol." "Calciferous" means containing or yielding calcium, from Latin "calx" (lime, limestone) plus the suffix "-ferous," meaning bearing or producing. "Sterol" is the chemical class name for the steroid alcohols, from "stereo-" (solid, three-dimensional) with the "-ol" ending used for alcohols. The name therefore describes the molecule's chemistry in a single word: a sterol that acts on calcium. The blend reflects the substance's discovery. Researchers were working out that irradiating certain sterols with ultraviolet light produced a compound that prevented rickets, and the name was chosen to point to both its calcium-related effect and its sterol structure. The word is a technical coinage rather than an old term that gained a new sense, so its meaning has stayed close to the chemistry it was built to name.
