'consistently' originates from Latin, specifically the word 'consistere,' where 'con-' meant 'together' and 'sistere' meant 'to stand.' 'Design' originates from Latin, specifically the word 'designare,' where 'de-' meant 'out' and 'signare' meant 'to mark.'

'consistere' transformed into the Old French word 'consister,' and eventually became the modern English word 'consist.' 'Designare' transformed into the Italian word 'disegnare,' and eventually became the modern English word 'design.'

Initially, 'consist' meant 'to stand together,' and 'design' meant 'to mark out,' but over time they evolved into their current meanings of 'being uniform' and 'to plan or create,' respectively.
