'wrongfully-declared' originates from the combination of 'wrongfully' and 'declared', where 'wrongfully' means 'in a manner that is not just or fair' and 'declared' means 'announced or stated'.

'wrongfully' comes from Old English 'wrang' meaning 'wrong' and 'fully' from 'full', while 'declared' comes from Latin 'declarare', meaning 'to make clear'.

Initially, 'wrongfully' meant 'in a wrong manner', and 'declared' meant 'to announce'. Together, they evolved to mean 'announced in an unjust manner'.
