'reconcile' originates from Latin, specifically the word 'reconciliare,' where 're-' meant 'again' and 'conciliare' meant 'to make friendly.'

'reconciliare' transformed into the Old French word 'reconcilier,' and eventually became the modern English word 'reconcile' through Middle English.

Initially, it meant 'to make friendly again,' and this meaning has largely remained the same in modern usage.
