Punished, as is right (9)
I believe the answer is:
corrected
'punished' is the definition.
(correcting is a kind of punishing)
'is right' is the wordplay.
I cannot quite understand how this works, but
'right' could be 'correct' (synonyms) and 'correct' is located in the answer.
The remaining letters 'ed' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'as' acts as a link.
Can you help me to learn more?
(Other definitions for corrected that I've seen before include "Removed errors" , "Amended" , "Adjusted or disciplined" .)
