ray: Ray the ‘beam of light or energy’ [14] and ray the fish-name [14] are two different words. The former comes from rai, the Old French descendant of Latin radius ‘spoke of a wheel, ray’ (source also of English radiant, radio, radius, etc). The textile term rayon was coined from it in the early 1920s. Ray the fish-name comes via Old French raie from Latin raia, a word of unknown origin.
=> radio, radius - ray (n.1)
- "beam of light," c. 1300, from Old French rai (nominative rais) "ray (of the sun), spoke (of a wheel); gush, spurt," from Latin radius "ray, spoke, staff, rod" (see radius). Not common before 17c. [OED]; of the sun, usually in reference to heat (beam being preferred for light). Science fiction ray-gun is first recorded 1931 (but the Martians had a Heat ray weapon in H.G. Wells' "War of the Worlds," 1898).
- ray (n.2)
- type of fish related to sharks, early 14c., from French raie (13c.), from Latin raia, of unknown origin.
