'advocatrice' originates from Latin, specifically the word 'advocatrix', where 'ad-' meant 'toward' and 'vocare' meant 'to call'.

'advocatrix' transformed into the French word 'advocatrice', and eventually became the modern English word 'advocatrice'.

Initially, it meant 'a female who calls or speaks for someone', but over time it evolved into its current meaning of 'a female advocate or supporter'.
