Etymology: "Isochron" is a modern compound built from two Greek elements: "isos," meaning "equal," and "chronos," meaning "time." Put together, the pieces describe something that takes the same amount of time each go-round, which is exactly what the word still means. The Greek roots are ancient, but the combined term is a later scientific coinage, not something Greek writers used. The "iso-" part is the same prefix you find in words like "isometric" or "isotope," where it signals equality or sameness. The "-chron" element, from "chronos," is the root behind "chronology," "synchronize," and "chronometer." Each of these borrows the Greek idea of time and then attaches a different prefix or suffix to shape a new meaning.
