After Disruption, find Free Church deviation (10)
I believe the answer is:
difference
'deviation' is the definition.
(synonyms)
'after disruption find free church' is the wordplay.
'after' is a charade indicator (letters next to each other).
'disruption' indicates an anagram.
'church' becomes 'CE' (abbreviation for Church of England).
'find'+'free'='findfree'
'findfree' is an anagram of 'differen'.
'differen'+'ce' is 'DIFFERENCE'.
(Other definitions for difference that I've seen before include "Variation" , "Diversity" , "Argument - dissimilarity" , "Change" , "Variance; disagreement" .)
