'biasedly-managed' originates from the English word 'bias,' which comes from the Old French word 'biais,' meaning 'slant or slope.' The suffix '-ly' is used to form adverbs, and 'managed' is the past participle of 'manage,' which comes from the Italian 'maneggiare,' meaning 'to handle.'

'bias' changed from the Old French word 'biais' and eventually became the modern English word 'bias.' 'Manage' evolved from the Italian 'maneggiare' to the modern English 'manage.'

Initially, 'bias' meant 'slant or slope,' but over time it evolved into its current meaning of 'prejudice or partiality.'
