Sinfulness in the village (4)
I believe the answer is:
evil
'sinfulness' is the definition.
(thesaurus)
'in the village' is the wordplay.
'in' indicates the answer is hidden within the clue.
'EVIL' can be found hidden inside 'the village'.
(Other definitions for evil that I've seen before include "Extremely unpleasant" , "Profoundly immoral" , "Villainy" , "Wicked, sinful" , "Malign" .)
