The word "bleach" traces back to Old English blǣcan, meaning "to whiten by exposure to light or chemicals." It shares roots with Old Norse bleikja (to bleach) and Proto-Germanic blaikjan (to make white), reflecting a long-standing association with lightening or purifying substances. The modern sense of chemical whitening emerged in the 18th century.
