'purported' originates from the Latin word 'proportare,' where 'pro-' meant 'forth' and 'portare' meant 'to carry.'

'proportare' transformed into the Old French word 'purporter,' and eventually became the modern English word 'purport' through Middle English.

Initially, it meant 'to carry forth or bring forward,' but over time it evolved into its current meaning of 'alleged or claimed.'
