'entitlement' originates from the English word 'entitle,' which comes from the Old French word 'entitler,' meaning 'to give a title or name to.'

'Entitler' transformed into the Middle English word 'entitlen,' and eventually became the modern English word 'entitle,' leading to 'entitlement.'

Initially, it meant 'to give a title or name,' but over time it evolved into its current meaning of 'having a right or claim to something.'
