'dishonest' originates from the Latin word 'dishonestus,' where 'dis-' meant 'apart' and 'honestus' meant 'honorable.'

'dishonestus' transformed into the Old French word 'deshoneste,' and eventually became the modern English word 'dishonest.'

Initially, it meant 'lacking honor,' but over time it evolved into its current meaning of 'not honest.'
