'effectively-adjusted' originates from the combination of 'effectively' and 'adjusted', where 'effectively' means 'in a manner that produces a desired result' and 'adjusted' means 'altered or modified'.

'Effectively' and 'adjusted' have been used separately in English since the 14th century, and their combination into 'effectively-adjusted' is a modern usage to describe something that has been modified to achieve a specific effect.

Initially, 'effectively' meant 'in a manner that produces a desired result', and 'adjusted' meant 'altered or modified'. The combination retains these meanings to describe something that has been modified to achieve a specific effect.
