'impudent' originates from Latin, specifically the word 'impudens,' where 'in-' meant 'not' and 'pudens' meant 'ashamed.'

'impudens' transformed into the Old French word 'impudent,' and eventually became the modern English word 'impudent' through Middle English.

Initially, it meant 'not feeling shame,' but over time it evolved into its current meaning of 'not showing due respect.'
