Etymology: "Velocimeters" is the plural of "velocimeter", an instrument for measuring speed. The word is built from two parts: "velocity", which comes from Latin "velocitas" meaning swiftness, and the suffix "-meter", from Greek "metron" meaning measure. Combining a Latin-derived noun with a Greek suffix is a common pattern in technical coinages, and the result follows the same logic as "thermometer" or "odometer". The first element, "veloci-", is a shortened form of "velocity", so the word literally means a measure of swiftness. Because the device reads out how fast something is moving, the name describes its function directly, with no metaphor involved. It is a plain technical formation rather than a word with a notable story attached, and the plural simply adds the regular "-s" ending.
