'accreditee' originates from the English word 'accredit,' which comes from the Latin word 'accreditare,' where 'ad-' meant 'to' and 'creditare' meant 'to entrust.'

'accreditare' transformed into the French word 'accréditer,' and eventually became the modern English word 'accredit' through Middle English.

Initially, it meant 'to entrust or give credit to,' but over time it evolved into its current meaning of 'to officially recognize or approve.'
