'nonpartisan' originates from the prefix 'non-' meaning 'not' and the word 'partisan,' which comes from the French 'partisan,' meaning 'supporter of a party.'

'partisan' changed from the French word 'partisan' and eventually became the modern English word 'partisan.' The prefix 'non-' was added to form 'nonpartisan.'

Initially, 'partisan' meant 'supporter of a party,' but with the prefix 'non-,' it evolved to mean 'not affiliated with any party.'
