Etymology: "Oleometer" is a plain technical coinage, built from "oleo-" and "-meter." The first part comes from Latin "oleum," meaning oil, which also gave English "oleic" and "olive" through a separate route. In the scientific vocabulary of the 19th and 20th centuries, "oleo-" became a standard combining form for anything oil-related, so this instrument's name simply declares its job: it measures the density of oil. The second element, "-meter," comes from Greek "metron," meaning measure, and it appears in countless instrument names such as thermometer and barometer. Put together, the word describes a device for measuring oil in exactly the way a hydrometer measures liquids in general. Its name follows a pattern chemists and engineers used freely whenever they needed a clear label for a new tool.
