'carefully-repaired' originates from the combination of 'carefully' and 'repaired', where 'carefully' is derived from 'care' meaning 'attention' and '-fully' meaning 'in a manner of'. 'Repaired' comes from the Latin 'reparare', where 're-' meant 'again' and 'parare' meant 'make ready'.

'carefully-repaired' changed from the Old French word 'reparer' and eventually became the modern English word 'repair', combined with 'carefully' to form the adjective.

Initially, 'repair' meant 'to make ready again', but over time it evolved into its current meaning of 'fixing something'.
