The English word 'whole' originates from the Old English adjective 'hāl', which carried the core senses of being unhurt, sound, and complete. This term is of Germanic origin, tracing back to the Proto-Germanic 'hailaz', a concept deeply connected to good health and wholeness. The semantic journey from the physical state of being "uninjured" to the more abstract concept of "entirety" or "the full amount" is a natural evolution, as something intact is inherently complete. Interestingly, the related word 'hale' (as in "hale and hearty") preserves the older meaning of sound health, while 'whole' expanded to encompass completeness and unity.

The word 'whole' is a simplex word derived from Old English 'hāl', meaning "sound, healthy, entire, complete." It is a Germanic root with cognates in other Germanic languages (e.g., Old Norse 'heill', Old High German 'heil').
