'consistently' originates from Latin, specifically the word 'consistere,' where 'con-' meant 'together' and 'sistere' meant 'to stand.' 'Continuing' comes from Latin 'continuare,' meaning 'to join together.'

'Consistere' transformed into the Old French word 'consister,' and eventually became the modern English word 'consistent.' 'Continuare' evolved into the Old French 'continuer,' leading to the modern English 'continue.'

Initially, 'consistently' meant 'standing together,' but over time it evolved into its current meaning of 'acting in a consistent manner.' 'Continuing' has largely retained its original meaning of 'to keep going.'
