'privately-shown' is a compound word formed from 'private' and 'shown'. 'Private' originates from Latin, specifically the word 'privatus', meaning 'withdrawn from public life'. 'Shown' is the past participle of 'show', which comes from Old English 'sceawian', meaning 'to look at'.

'Privatus' transformed into the Old French word 'privé', and eventually became the modern English word 'private'. 'Sceawian' evolved into the Middle English 'schewen', and eventually became 'show'.

Initially, 'private' meant 'withdrawn from public life', and 'shown' meant 'to look at'. Together, they evolved to mean 'displayed in a private setting'.
