'accidentally-repaired' originates from the combination of 'accidentally' and 'repaired', where 'accidentally' means 'by chance' and 'repaired' means 'fixed or restored'.

'accidentally' comes from the Latin word 'accidentalis', and 'repaired' comes from the Old French 'reparer', which eventually became the modern English word 'repair'.

Initially, 'accidentally' meant 'by chance', and 'repaired' meant 'fixed'. The combination retains these meanings, indicating a chance restoration.
