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

'advocatus' transformed into the Old French word 'avocat,' and eventually became the modern English word 'advocate,' with 'advocatess' as a gender-specific variant.

Initially, it meant 'one who is called to aid,' but over time it evolved into its current meaning of 'a supporter or defender.'
