'agentship' originates from the word 'agent', which comes from Latin 'agentem', the present participle of 'agere', meaning 'to do, act'.

'agentem' transformed into the Old French word 'agent', and eventually became the modern English word 'agent'.

Initially, it meant 'one who acts or does', but over time it evolved into its current meaning of 'a person who acts on behalf of another'.
