'paganism' originates from Latin, specifically the word 'paganus,' where 'paganus' meant 'country dweller' or 'rustic.'

'paganus' transformed into the Old French word 'paien,' and eventually became the modern English word 'paganism' through Middle English.

Initially, it meant 'country dweller,' but over time it evolved into its current meaning of 'a belief system outside of the main world religions.'
