Put clothes back on? Correct! (7)
I believe the answer is:
redress
'correct' is the definition.
(I know that correct can be written as redress)
'put clothes back on?' is the wordplay.
I cannot really see how this works, but
'clothes' could be 'dress' (dress is a kind of clothes) and 'dress' is found within the answer.
'on?' could be 're' ('on' can be mean 'with reference to') and 're' is found 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 redress that I've seen before include "Put right" , "set straight again" , "Get back into gear" , "Reparation" , "Set right - compensation" .)
