Etymology: "Thermohygrometer" is a compound built from two older instruments. Its first half, "thermo-", comes from Greek "thermos", meaning "hot" or "warm", and it appears in English words such as "thermometer" and "thermostat". The second half is "hygrometer", an instrument for measuring humidity, which combines Greek "hygros", meaning "wet" or "moist", with "-meter", meaning "measure". Joining the two produced a single device that reads temperature and moisture together. The logic of the name is simple: the thermometer and the hygrometer were separate tools for most of their history, and this word describes the combined instrument that does both jobs. Its structure is transparent enough that a reader who knows the parts can work out the meaning at once.
