Etymology: "Urinometers" is the plural of "urinometer", a gauge for measuring how dense urine is. The name is a straightforward compound built from "urine", a linking "-o-", and "-meter", and the final element traces back to the Ancient Greek "métron", meaning "measure". The word therefore says exactly what the instrument does: it measures urine. The "-meter" ending is the interesting part. In Ancient Greek, "métron" was a general word for measure, and the suffix "-tron" marked an instrument or means of doing something. It passed into French as "-mètre" and then into English as "-meter", where it became one of the most productive ways of naming measuring devices, from thermometers to barometers. "Urinometer" follows that pattern, pairing the Latin-derived "urine" with a Greek-derived measuring element, a mix common in scientific coinages.
