'impolite' originates from Latin, specifically the word 'impolitus', where 'im-' meant 'not' and 'politus' meant 'polished or refined'.

'impolitus' transformed into the French word 'impoli', and eventually became the modern English word 'impolite' through Middle English.

Initially, it meant 'not polished or refined', but over time it evolved into its current meaning of 'not having or showing good manners'.
