'energy-adjusting' originates from Modern English, specifically a compound of 'energy' and the present-participle form 'adjusting'. 'energy' comes (via Latin and Old French) from Greek 'energeia', and 'adjusting' comes from the verb 'adjust' (Old French 'ajuster') formed with the present participle ending '-ing'.

'energy' comes from Greek 'energeia' → Latin 'energia' → Old French/Medieval Latin forms → Modern English 'energy'. 'adjust' passed into English from Old French 'ajuster' (to make right or fit) and developed English verb forms; the compound 'energy-adjusting' is a modern English formation combining the noun and a participle.

Individually, 'energy' referred to force, activity, or effective operation and 'adjust' meant to make small changes for fit or function; combined in modern usage they form a compound meaning 'making changes to regulate or balance energy', often with physical, emotional, or metaphysical nuance.
