'emancipation' originates from Latin, specifically the word 'emancipatio,' where 'e-' meant 'out' and 'mancipare' meant 'to deliver.' 'Advocate' originates from Latin, specifically the word 'advocatus,' where 'ad-' meant 'to' and 'vocare' meant 'to call.'

'emancipatio' transformed into the French word 'émancipation,' and eventually became the modern English word 'emancipation.' 'Advocatus' transformed into the French word 'avocat,' and eventually became the modern English word 'advocate.'

Initially, 'emancipation' meant 'to deliver from control,' and this meaning has largely remained the same in modern usage. 'Advocate' initially meant 'one who is called to aid,' and now it means 'to support or promote.'
