Adapt commercial according to what is morally right (6)
I believe the answer is:
adjust
'adapt' is the definition.
(I know that adapt can be written as adjust)
'commercial according to what is morally right' is the wordplay.
I cannot quite understand how this works, but
'commercial' could be 'ad' (abbreviation for advertisement) and 'ad' is present in the answer.
'right' could be 'just' (similar in meaning) and 'just' is located in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for adjust that I've seen before include "Bring small change" , "Adapt (oneself)" , "Adapt, regulate" , "Alter, adapt" , "Calibrate or regulate" .)
