A decent reform carried out (7)
I believe the answer is:
enacted
'carried out' is the definition.
The answer and definition can be both to do with creating things as well as being past participle verbs.
Maybe you can see an association between them that I can't see?
'a decent reform' is the wordplay.
'reform' indicates an anagram (letters in a new form).
'a'+'decent'='adecent'
'adecent' is an anagram of 'ENACTED'.
Can you help me to learn more?
(Other definitions for enacted that I've seen before include "A decent (anag.)" , "Passed legislation" , "Made a bill into law" , "Performed as in a play, or passed into law" , "Represented" .)
