köken: súg (“to whisper”) + -ár (noun-forming suffix). The verb súg is in origin an onomatopoeia corresponding to English rustle, so the original meaning of sugár may have been a rustling object. The several other current meanings are the result of a name transfer process. The geometry sense of radius was patterned after Latin, compare radius (“ray; staff, rod; spoke of a wheel”).
a staff, rod · a rod for measurement · the radius of a circle; a rotating radial arm

May ultimately be from Proto-Indo-European *reh₁t- (“bar, beam, stem”).
