'effectively-combined' originates from the English words 'effective' and 'combine', where 'effective' meant 'producing a desired result' and 'combine' meant 'to bring together'.

'effectively' and 'combine' were used separately in Middle English and eventually merged to form the modern English term 'effectively-combined'.

Initially, it meant 'to bring together in a way that works well', and this meaning has largely remained the same in modern usage.
