'unfairly-assessed' originates from the combination of 'unfairly' and 'assessed', where 'unfairly' is derived from 'un-' meaning 'not' and 'fair' meaning 'just or equitable', and 'assessed' is the past participle of 'assess', which comes from Latin 'assessus', meaning 'to sit beside or assist'.

'assess' changed from the Latin word 'assessus' to the Old French 'assesser', and eventually became the modern English word 'assess'.

Initially, 'assess' meant 'to sit beside or assist', but over time it evolved into its current meaning of 'to evaluate or judge'.
