'flawless' originates from Middle English, specifically the word 'flawles,' where 'flaw' meant 'defect' and '-less' meant 'without.'

'flawles' transformed into the modern English word 'flawless' by the addition of the suffix '-ness' to form the noun 'flawlessness.'

Initially, it meant 'without defects,' and this meaning has largely remained the same in modern usage.
