'consistently-produced' originates from the combination of 'consistent' and 'produce', where 'consistent' comes from Latin 'consistere', meaning 'to stand firm', and 'produce' from Latin 'producere', meaning 'to lead forward'.

'consistere' transformed into the Old French word 'consister', and eventually became the modern English word 'consistent'. 'Producere' transformed into the Old French word 'produire', and eventually became the modern English word 'produce'.

Initially, 'consistent' meant 'standing firm', but over time it evolved into its current meaning of 'uniform and regular'. 'Produce' initially meant 'to lead forward', evolving into 'to create or manufacture'.
