'revocation' originates from Latin, specifically the word 'revocatio,' where 're-' meant 'back' and 'vocare' meant 'to call.'

'revocatio' transformed into the Old French word 'revocacion,' and eventually became the modern English word 'revocation' through Middle English.

Initially, it meant 'to call back or withdraw,' and over time it evolved into its current meaning of 'official cancellation.'
