Reformed middleman patched things up (7)
I believe the answer is:
amended
'up' is the definition.
Both the answer and definition are adjectives. Perhaps you can see a link between them that I don't see?
'reformed middleman patched' is the wordplay.
'reformed middleman' becomes 'a' (I can't explain this - if you can you should believe this answer much more).
'patched' becomes 'mended' (I've seen this in another clue).
'a'+'mended'='AMENDED'
'things' is the link.
Can you help me to learn more?
(Other definitions for amended that I've seen before include "Revised or altered" , "Put right" , "Correct, improve" , "Made changes to correct" , "Edited" .)
