'biasedly-performed' originates from the English word 'bias,' which comes from Old French 'biais,' meaning 'oblique' or 'slanting.' The suffix '-ly' is used to form adverbs, and 'performed' is derived from the Latin 'performare,' meaning 'to form thoroughly.'

'bias' changed from the Old French word 'biais' and eventually became the modern English word 'bias.' 'Perform' evolved from the Latin 'performare' through Old French 'parfournir.'

Initially, 'bias' meant 'oblique' or 'slanting,' but over time it evolved into its current meaning of 'prejudice or inclination.'
