'implicitly-shown' originates from the combination of 'implicit' and 'shown', where 'implicit' comes from Latin 'implicitus', meaning 'entangled', and 'shown' is the past participle of 'show', from Old English 'sceawian', meaning 'to look at'.

'implicitus' transformed into the English word 'implicit', and 'sceawian' evolved into 'show', eventually forming the modern English term 'implicitly-shown'.

Initially, 'implicit' meant 'entangled', but over time it evolved to mean 'implied or understood without being directly stated'.
