The term 'later-shown' is a compound word formed from 'later' and 'shown'. 'Later' originates from Old English 'lætra', meaning 'slower', and 'shown' is the past participle of 'show', which comes from Old English 'sceawian', meaning 'to look at'.

'Later' evolved from Old English 'lætra' and 'shown' from 'sceawian', eventually forming the modern English compound 'later-shown'.

Initially, 'later' meant 'slower', and 'shown' meant 'to look at', but together they evolved to mean 'revealed at a subsequent time'.
