'unprejudiced' originates from the prefix 'un-' meaning 'not' and the word 'prejudiced,' which comes from the Latin 'praejudicium,' meaning 'prior judgment.'

'prejudiced' changed from the Old French word 'prejudicier' and eventually became the modern English word 'prejudiced.'

Initially, it meant 'not influenced by prior judgment,' and this meaning has largely remained the same in modern usage.
