Etymology: Prednisone is a compound built from three chemical name fragments, and its name is a tidy record of how steroid chemistry was named in the twentieth century. The first part, "pred," comes from "pre(gnane)," the name of a parent steroid structure that itself descends from the Latin "praegnans," meaning "pregnant," a reference to the pregnancy hormones in which this kind of ring structure was first studied. The middle part, "nis," stands for "d(ie)ne," a reference to the two double bonds in the molecule's rings, and the final part is "(cort)isone," from cortisone, the hormone made by the adrenal cortex, whose own name draws on the Latin "cortex," meaning bark or outer layer. Since prednisone is a synthetic modification of cortisone rather than a naturally occurring hormone, the word is a coinage of modern pharmaceutical chemistry. It was built by joining these fragments in the same way that chemists name related compounds, so the word works less like a traditional English word and more like a short chemical formula written in sounds.
