Went and made good (8)
I believe the answer is:
repaired
'went' is the definition.
(I've seen this before)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for repaired that I've seen before include "Fixed" , "Put right - went" , "Mended, restored" , "Retired" , "Restored to good condition" .)
