'flawlessly-repaired' originates from the combination of 'flawless' and 'repaired'. 'Flawless' comes from 'flaw', which originates from Old Norse 'flaga', meaning 'slab' or 'flake', and 'less', a suffix meaning 'without'. 'Repaired' comes from Latin 'reparare', where 're-' meant 'again' and 'parare' meant 'prepare'.

'Flawless' evolved from Middle English 'flawles', and 'repaired' from Middle English 'repairen', eventually forming the modern English term 'flawlessly-repaired'.

Initially, 'flawless' meant 'without a crack or defect', and 'repaired' meant 'to restore'. Together, they evolved to mean 'restored without any defects'.
