'disreputable' originates from the Latin word 'reputare,' where 're-' meant 'again' and 'putare' meant 'to think.'

'reputare' transformed into the French word 'réputer,' and eventually became the modern English word 'repute,' with 'dis-' added to form 'disreputable.'

Initially, it meant 'to think again or reconsider,' but over time it evolved into its current meaning of 'not respectable.'
