'consistently-joined' originates from the English word 'consistent,' which comes from the Latin word 'consistere,' where 'con-' meant 'together' and 'sistere' meant 'to stand.'

'consistere' transformed into the Old French word 'consister,' and eventually became the modern English word 'consistent.' The word 'joined' comes from the Latin 'jungere,' meaning 'to join.'

Initially, 'consistent' meant 'standing together,' but over time it evolved into its current meaning of 'acting or done in the same way over time.'
