'reconciliation' originates from Latin, specifically the word 'reconciliatio,' where 're-' meant 'again' and 'conciliatio' meant 'bringing together.'

'reconciliatio' transformed into the Old French word 'reconciliation,' and eventually became the modern English word 'reconciliation' through Middle English.

Initially, it meant 'bringing together again,' but over time it evolved into its current meaning of 'restoration of friendly relations.'
