Etymology: The "work" in ergometer comes from ancient Greek "ergon," meaning work or deed, a word that also gave English "energy" and "erg," the unit of work. The "-meter" half comes from Greek "metron," measure, the same root behind "thermometer" and "barometer." Put together, an ergometer is literally a work-measurer. The compound is a modern coinage built from these classical pieces, not a term that Greeks or Romans ever used for a machine. It arrived in English as a technical name for instruments that record how much physical effort a person or machine puts out, which is why the word sounds more like a laboratory term than an everyday one.
