A decent revolutionary made law (7)
I believe the answer is:
enacted
'made law' is the definition.
(I've seen this before)
'a decent revolutionary' is the wordplay.
'revolutionary' indicates anagramming the letters.
'a'+'decent'='adecent'
'adecent' is an anagram of 'ENACTED'.
(Other definitions for enacted that I've seen before include "Passed legislation" , "Represented" , "Performed as in a play, or passed into law" , "Made a bill into law" , "Put into practice" .)
