Etymology: Algesiometer is a technical coinage built from Greek roots. The first part comes from "algos," the Greek word for pain, and the second from "metron," meaning measure, the same element found in thermometer and barometer. Put together, the name describes an instrument for measuring pain, and the word is a close synonym of "algometer," which is built on the same pattern with the same first element. The construction is a plain example of scientific naming in which Greek parts are combined to label a new device. Because the pieces are transparent, the word needs little unpacking: "algesi-" carries the pain sense and "-meter" supplies the act of measurement. Ancient Greek speakers had no such instrument, so the word belongs to the modern vocabulary of medicine and physiology rather than to classical usage.
