Etymology: "Pyretogenous" is a synonym of "pyrogenic," and it is built from the same Greek building blocks. The first part comes from Greek "pyr," meaning fire, which gave English words like pyre and pyrotechnics. The second part, "-genous," comes from Greek "-genēs," meaning born of or produced by, so the literal sense is something that produces or gives rise to heat. The word belongs to the scientific and medical vocabulary that took shape in the modern period, when writers drew on classical Greek roots to name newly observed phenomena. Its meaning is precise: agents such as bacterial toxins or certain cytokines that raise the body's set point and bring on fever. Like many such coinages, it reads as ancient but was assembled from old parts to describe a concept that the Greeks themselves never framed in these terms.
