'discloser' originates from the Old French word 'disclos,' where 'dis-' meant 'apart' and 'clos' meant 'closed.'

'disclos' transformed into the Middle English word 'disclose,' and eventually became the modern English word 'discloser.'

Initially, it meant 'to open or uncover,' but over time it evolved into its current meaning of 'a person who reveals something.'
