Etymology: "Hodometer" is a compound built from two Greek-derived parts: "hodo-", from Greek "hodos," meaning "way" or "road," and "-meter," from Greek "metron," meaning "measure." Put together, the name describes an instrument that measures the road travelled. The spelling is the surprise. Most English speakers know the instrument as the "odometer," and the "h" in "hodometer" is an older spelling that reflects the Greek original, which begins with a rough breathing mark. English dropped that "h" in many borrowed words, so the form that survived in everyday use is the shorter one. "Hodometer" is the variant that keeps the Greek letter visible. The word is a technical coinage built from classical elements, so there is no older English sense to trace. It describes a device that totals distance over time, and the Greek parts do all the work of explaining what it is.
