Etymology: "Dynos" is the plural of "dyno," a clipped form of "dynamometer," the instrument that measures force or power output. Dynamometers were named from Greek roots: "dynamis" meaning force or power, and "metron" meaning measure. The shortened "dyno" came into use in informal speech, and its plural "dynos" follows the ordinary English pattern of adding -s. Hmm, but this entry is an inflected form, so the response should be brief. Here is the revised version as one paragraph: "Dynos" is the plural of "dyno," a clipped form of "dynamometer," an instrument that measures force or power. The full word combines the Greek "dynamis," meaning force or power, with "metron," meaning measure. In everyday use, "dynos" is most often applied to tests of an engine's horsepower on a rolling road.

Synonyms: dynamometers, engine testers, power meters
