'wholesomely' originates from English, specifically the word 'wholesome' with the suffix '-ly', where 'wholesome' meant 'promoting health or well-being' and '-ly' forms an adverb.

'Wholesome' comes from Middle English 'holsom', from 'hol' (whole, healthy) + '-som' (some), and '-ly' was added to form the adverb 'wholesomely'.

Initially, it meant 'in a way that is healthy or beneficial', and this meaning has largely remained the same in modern usage.
