Etymology

brightness = bright<shining> + ness<noun suffix>

  • bright: From Old English beorht (radiant, clear), related to Proto-Germanic berhtaz. Originally described light or color intensity, later extended to mental sharpness.
  • ness: A noun-forming suffix from Old English -nes, indicating a state or quality (e.g., darkness, kindness).

Etymology Origin:
The word evolved from Old English beorhtnes, combining beorht (bright) with -nes (state of). Over time, beorht simplified to "bright," while -nes became "-ness." The term initially described physical light but expanded metaphorically to denote intellectual brilliance.
