Husband again appears to make good (7)
I believe the answer is:
restore
'make good' is the definition.
'restore' can be an answer for 'make' (thesaurus). I'm not certain of the 'good' bit.
'husband again appears' is the wordplay.
I cannot really see how this works, but
'husband' could be 'store' (I've seen this in another clue) and 'store' is found within the answer.
'again' could be 're' (prefix meaning 'again') and 're' is present in the answer.
No letters remain.
This explanation may well be incorrect...
'to' acts as a link.
Can you help me to learn more?
(Other definitions for restore that I've seen before include "Bring back, reinstate" , "Bring back; renovate" , "Strengthen" , "Make good, reinstate" , "Bring back to health" .)
