'consistently' originates from Latin, specifically the word 'consistere,' where 'con-' meant 'together' and 'sistere' meant 'to stand.' 'Done' comes from Old English 'don,' meaning 'to perform or execute.'

'consistere' transformed into the French word 'consister,' and eventually became the modern English word 'consist.' 'Don' evolved into 'done' in Middle English.

Initially, 'consistently' meant 'standing together,' but over time it evolved into its current meaning of 'in a consistent manner.' 'Done' has largely retained its original meaning of 'performed or executed.'
