Put the bedclothes back on to get better? (7)
I believe the answer is:
recover
'get better?' is the definition.
(synonyms)
'put the bedclothes back on' is the wordplay.
I cannot really see how this works, but
'bedclothes' could be 'cover' (cover is a kind of bedclothes) and 'cover' is present in the answer.
'on' could be 're' (regarding) and 're' is found in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'to' is the link.
Can you help me to learn more?
(Other definitions for recover that I've seen before include "Rally, get better" , "Get well again" , "Bring back" , "Regain" , "Get better; retrieve" .)
