'consistently-combined' originates from the English words 'consistent' and 'combine', where 'consistent' means 'acting or done in the same way over time' and 'combine' means 'to unite or merge'.

'Consistently' and 'combined' were used separately in English before being hyphenated to form the modern term 'consistently-combined'.

Initially, it meant 'to be mixed in a regular manner', and this meaning has largely remained the same in modern usage.
