'consistently' originates from Latin, specifically the word 'consistere,' where 'con-' meant 'together' and 'sistere' meant 'to stand.' 'Grown' comes from Old English 'grōwan,' meaning 'to grow or flourish.'

'consistere' transformed into the Old French word 'consister,' and eventually became the modern English word 'consistent.' 'Grōwan' evolved into the Middle English 'growen,' and eventually became 'grown.'

Initially, 'consistently' meant 'standing together,' but over time it evolved into its current meaning of 'in a consistent manner.' 'Grown' has largely retained its original meaning of 'to develop or increase in size.'
