'deliberately-demonstrated' originates from the combination of 'deliberately' and 'demonstrated', where 'deliberately' comes from Latin 'deliberatus', meaning 'considered carefully', and 'demonstrated' from Latin 'demonstratus', meaning 'pointed out'.

'deliberately-demonstrated' combines the English words 'deliberately' and 'demonstrated', which have been used in English since the 16th and 17th centuries respectively.

Initially, 'deliberately' meant 'with careful consideration', and 'demonstrated' meant 'shown clearly'. Together, they evolved to mean 'intentionally shown'.
