'consistently' originates from Latin, specifically the word 'consistere,' where 'con-' meant 'together' and 'sistere' meant 'to stand.' 'Associated' comes from Latin 'associare,' where 'ad-' meant 'to' and 'sociare' meant 'to join.'

'Consistere' transformed into the Old French word 'consister,' and eventually became the modern English word 'consist.' 'Associare' transformed into the Old French word 'associer,' and eventually became the modern English word 'associate.'

Initially, 'consist' meant 'to stand together,' and 'associate' meant 'to join.' Over time, 'consistently-associated' evolved to mean 'regularly linked or connected.'
