'boldly-declared' originates from the combination of 'boldly' and 'declare', where 'boldly' comes from Old English 'beald' meaning 'brave' and 'declare' from Latin 'declarare' meaning 'to make clear'.

'boldly' changed from Old English 'beald' to Middle English 'bold', and 'declare' from Latin 'declarare' to Old French 'declarer', eventually becoming the modern English 'declare'.

Initially, 'boldly' meant 'brave' and 'declare' meant 'to make clear', but over time, 'boldly-declared' evolved to mean 'confidently stated'.
