súg (to whisper) +‎ -ár (noun-forming suffix). The verb súg has a sound-immitating origin of rustling sound, 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).[1]
