the word 'unwholesome' is a native english formation built from germanic elements. its core, 'whole,' originates from the old english 'hāl,' which conveyed the ideas of being unhurt, sound in body, and complete—a concept also preserved in the related modern word 'health.' the suffix '-some' was added to create the adjective 'wholesome,' meaning "conducive to health or well-being." finally, the negative prefix 'un-' was attached, directly inverting the meaning to "not conducive to health," a sense which expanded metaphorically to describe things considered morally or psychologically detrimental.

Structure: un (not) + whole (healthy, complete) + some (characterized by) - un: a prefix of germanic origin (old english) meaning "not," serving a negating function. - whole: from old english 'hāl' meaning "sound, healthy, entire." in this compound, it carries the sense of "healthy." - some: an adjective-forming suffix from old english '-sum,' meaning "characterized by, tending to."
