Goes and fixes things (7)
I believe the answer is:
repairs
'fixes things' is the definition.
'repairs' can be an answer for 'fixes' ('repair' can be a synonym of 'fix'). I am not certain of the 'things' bit.
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for repairs that I've seen before include "makes good" , "Doctors" , "Withdraws" , "Restores" , "Mends, fixes" .)
