Etymology

Origin of ray¹

First recorded in 1350–1400; Middle English rai, raie, raye, from Old French rai “beam of light; spoke of a wheel,” from Latin radius radius

Origin of ray²

First recorded in 1275–1325; Middle English rai(e), raye, (from Old French rai ) or directly from Latin raia

Explanation

A ray is a beam of light or radiation. Even on cloudy days, you sometimes see a ray of sunlight shine through the clouds. In physics, a ray is a line or column of light, heat, or electromagnetic radiation (like an x-ray), while in math a ray is a line that passes through a specific point. A marine biologist would define a ray as a big fish that's related to sharks and has a wide, flat body and a long tail. The root of the first two kinds of rays is the Latin word radius, "spoke" or "staff."
