'ethic' originates from Greek, specifically the word 'ēthikos,' where 'ēthos' meant 'character' or 'custom.'

'ēthikos' transformed into the Latin word 'ethicus,' and eventually became the modern English word 'ethic' through Old French 'ethique.'

Initially, it meant 'pertaining to character,' but over time it evolved into its current meaning of 'moral principles or values.'
