Imply finer reform (5)
I believe the answer is:
infer
'imply' is the definition.
(I've seen this before)
'finer reform' is the wordplay.
'reform' indicates an anagram (letters in a new form).
'finer' anagrammed gives 'INFER'.
(Other definitions for infer that I've seen before include "Deduce logically" , "Deduce, surmise" , "Work out" , "Derive by reasoning" , "Draw a conclusion" .)
