'uncivil' originates from Latin, specifically the word 'incivilis,' where 'in-' meant 'not' and 'civilis' meant 'civil or courteous.'

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

Initially, it meant 'not civil or courteous,' and this meaning has largely remained the same in modern usage.
