'regularly-shown' originates from the combination of 'regularly' and 'shown', where 'regularly' comes from Latin 'regularis' meaning 'consistent' and 'shown' is the past participle of 'show', from Old English 'sceawian'.

'regularly' evolved from Middle English 'regular' and 'shown' from Old English 'sceawian', eventually forming the modern English compound adjective 'regularly-shown'.

Initially, 'regularly' meant 'in a consistent manner' and 'shown' meant 'to display', and together they have maintained the meaning of 'displayed consistently'.
