'consistently' originates from Latin, specifically the word 'consistere,' where 'con-' meant 'together' and 'sistere' meant 'to stand.' 'Shown' comes from Old English 'sceawian,' meaning 'to look at or see.'

'Consistently' evolved from the Latin 'consistere' through Old French 'consister,' and 'shown' evolved from Old English 'sceawian' to the modern English 'show.'

Initially, 'consistently' meant 'standing together,' but over time it evolved into its current meaning of 'in a regular manner.' 'Shown' has largely retained its original meaning of 'to display or demonstrate.'
