'distinctiveness' originates from Latin, specifically the word 'distinctus,' where 'dis-' meant 'apart' and 'stinguere' meant 'to prick or mark.'

'distinctus' transformed into the Old French word 'distinctif,' and eventually became the modern English word 'distinctive' through Middle English.

Initially, it meant 'to mark apart,' but over time it evolved into its current meaning of 'unique or distinguishing quality.'
