Etymology of RADIUS

The word "radius" originated from Latin and can be traced back to the ancient Greek word "rhoádon", meaning "rod" or "wand". This Greek term was used to describe the spoke of a wheel, a staff, or a beam. In Latin, "radius" took on multiple meanings, including "ray of light" and "spoke of a wheel". Over time, its usage narrowed down to primarily refer to the bone in the forearm (which is straight like a rod) and subsequently to any line segment extending from the center of a circle to its circumference.
