Sin not recorded from the East (4)
I believe the answer is:
evil
'sin' is the definition.
(I've seen this in another clue)
'not recorded from the east' is the wordplay.
'not recorded' becomes 'live' ('live' is the opposite to 'recorded').
'from the east' shows that the letters should be reversed in order (on a map from right to left).
'live' back-to-front is 'EVIL'.
(Other definitions for evil that I've seen before include "Harmful; unlucky" , "Morally bad" , "Wicked, sinful" , "Morally corrupt" , "Malign" .)
