Put clothes back on? Correct! (7)
I believe the answer is:
redress
'correct' is the definition.
(synonyms)
'put clothes back on?' is the wordplay.
I cannot quite understand 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 located in the answer.
No letters remain.
This explanation may well be incorrect...
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" .)
