'openly-declared' originates from the combination of 'openly' and 'declare,' where 'openly' means 'without concealment' and 'declare' means 'to announce or state.'

'Openly' and 'declare' have been used in English since the Middle Ages, with 'declare' coming from the Latin 'declarare,' meaning 'to make clear.'

Initially, 'declare' meant 'to make clear,' and 'openly' meant 'without concealment.' The combination retains these meanings in modern usage.
