'health' originates from Old English, specifically the word 'hǣlþ,' where 'hāl' meant 'whole' or 'uninjured.'

'hǣlþ' changed from Old English to Middle English as 'helthe' and eventually became the modern English word 'health'.

Initially, it meant 'wholeness or soundness,' but over time it evolved into its current meaning of 'state of being free from illness or injury.'
