healthfully

The word 'healthfully' is a layered construction built upon the ancient Germanic concept of wholeness. Its core, 'health', originates from the Old English 'hǣlþ', which itself derives from the Proto-Germanic 'hailithō', a noun formed from the root 'hailaz' meaning 'whole, uninjured, of good omen'. The suffix '-ful' (Old English '-ful') was added to create the adjective 'healthful', literally meaning 'full of wholeness' or 'characteristic of good health'. Finally, the adverbial suffix '-ly' (from Old English '-līce', meaning 'having the manner of') was appended, creating a word that describes an action performed in a manner that embodies or promotes completeness and soundness of body. Thus, the modern abstract meaning of performing actions in a wellness-promoting way is a direct logical extension of its literal morphemic parts: 'in the manner of being full of wholeness'.
