Etymology

The word "light" has a dual origin in Old English:

  1. From lēoht (brightness, radiant energy), derived from Proto-Germanic leuhtam, linked to the Proto-Indo-European root leuk- (to shine, brightness).
  2. From līht (not heavy), from Proto-Germanic linhtaz, related to linghw- (lightweight).
    Over time, the spelling merged, but the meanings remained distinct. The shared concept of "lack of heaviness" (in weight or visual intensity) connects both strands.
