'unjustly-announced' originates from the combination of 'unjustly' and 'announced', where 'unjustly' is derived from 'unjust', meaning 'not just', and 'announced' from 'announce', meaning 'to make known publicly'.

'unjustly' evolved from the Old French 'injuste', and 'announce' from the Latin 'annuntiare', eventually forming the modern English compound 'unjustly-announced'.

Initially, 'unjustly' meant 'not fair', and 'announce' meant 'to declare', which together have retained their meanings in the compound form.
