'unfairly-proclaimed' originates from the combination of 'unfairly' and 'proclaimed'. 'Unfairly' comes from 'unfair', which is derived from Old English 'unfæger', meaning 'not beautiful or pleasing'. 'Proclaimed' comes from Latin 'proclamare', where 'pro-' meant 'forth' and 'clamare' meant 'to shout'.

'unfairly-proclaimed' combines the adverb 'unfairly' with the past participle 'proclaimed', forming a modern English adjective.

Initially, 'proclaim' meant 'to shout forth', but in combination with 'unfairly', it evolved to mean 'declared in an unjust manner'.
